Type USG Ultra-Stable Precision High Voltage Resistors

Lowest TC High Voltage Resistor, 10 ppm/

C from -40

C to +85

C reference to +25

0.10% Tolerance, Three body sizes providing voltage ratings of 5KV, 10KV, and 15KV

The very highest performance high voltage applications require

the best possible temperature coefficient and long term stability

from the high voltage resistors that are used in these applications.

To meet these demanding requirements Caddock introduces the

Type USG Ultra-Stable Precision High Voltage Resistors. Utilizing

our proven Tetrinox

resistance film system, these Type USG

resistors were developed to optimize low temperature coefficient

performance and long term stability performance. By utilizing

specific ceramic core materials with optimum Tetrinox

processing

we are able to control, very tightly in manufacturing, the important

ultra-stable performance parameters in operating temperatures

from -40C to +85C. This unique process is offered in specific

resistance values in three body sizes. The extraordinary operating

stability of the Type USG resistors will improve the performance

of your high voltage system.

The performance features of the Type USG Ultra Stable

Precision High Voltage Resistors are:

· Temperature Coefficient: 10 ppm/C from -40C to +85C.

· Tolerance: 0.10%

· Typical Load Life Stability of 0.025% per 1,000 hours

at +85C, 0.05% per 1000 hrs. maximum.

· Three body sizes provide continuous voltage ratings of 5KV,

10KV, and 15KV.

· The specific resistances that are offered in each body size,

have been selected for produceability of optimum performance.

· The Ultra Low Temperature Coefficient minimizes self

heating (warm-up) drift following the application of high

voltage or resulting from a change in the applied high voltage.

· Custom Low TC HV Strings are available: 50KV, 100KV, etc.

Precise Voltage Division Ratio performance can be formed using Type USG

Ultra-Stable High Voltage Resistors together with Caddock's Type USF

Ultra-Stable Precision Film Resistors or "matched" with selected Type TK Low

TC Precision Radial-Lead Resistors. Consult Caddock Applications

Engineering to optimize voltage division ratio performance for your

application. The Low TC of the Type USG resistors minimizes temperature

related drift due to temperature gradients that may exist due to the

placement of the resistor components in the high voltage

assembly.

Now with Extended Resistance Range to 10,000 Megohms and Additional Models

Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.

Caddock's Micronox

resistance films are the source of

the Type MG Precision High Voltage Resistors' outstanding

combination of performance features:

Single-resistor values as high as 10,000 Megohms.

Maximum continuous operating voltages as high as

48,000 volts ("-15" ratings).

Overvoltage capabilities of 150% of standard working

voltages for all models and values, (except "-15" ratings).

Resistance Tolerances from ±1.0% to ±0.1%.

Temperature Coefficient, for standard resistance range, of

80 ppm/°C in combination with resistance tolerances as

tight as ±0.1%.

Type MG resistors have demonstrated stability of 0.01%

per 1,000 hours in extended load life testing of standard

resistance range values.

This exceptional performance has been proven through

many years of use in equipment that demands the highest

reliability and stability, including TWT amplifiers, X-ray

systems, geophysical instruments, and medical electronics.

Preconditioning for Power and Voltage Ratings

All power ratings and maximum operating voltage ratings

are for continuous duty. These ratings are based on pre-

stress voltage levels applied during the manufacturing

process to provide for stable resistor performance even

under momentary overload conditions.

Maximum operating voltages 60% higher than the values

listed in the table may be specified by adding "-15" to the

model number (Example: MG750-15). Note that overload

and overvoltage ratings do not apply to the "-15" resistors.

Resistance ranges for "-15" resistors shown in the table are

from "-15 Min." to "Standard Max."

Non-Inductive Performance

Most models are manufactured with Caddock's

Non-Inductive Design which uses a serpentine resistive

pattern that provides for neighboring lines to carry current in

opposite directions, thereby achieving maximum cancellation

of flux fields over the entire length of the resistor. This

efficient non-inductive construction is accomplished without

derating of any performance advantages.

Insulation Resistance: 10,000 Megohms, min.

Overload/Overvoltage: 5 times rated power

with applied voltage not to exceed 1.5 times max-

imum continuous operating voltage for 5 seconds

Temperature Coefficient as tight as 80 ppm/°C, Combined with Excellent Long-Term Stability and Precision Tolerances.

Caddock's Micronox

resistance films are the source of

the Type MG Precision High Voltage Resistors' outstanding

combination of performance features:

Single-resistor values as high as 10,000 Megohms.

Maximum continuous operating voltages as high as

48,000 volts ("-15" ratings).

Overvoltage capabilities of 150% of standard working

voltages for all models and values, (except "-15" ratings).

Resistance Tolerances from ±1.0% to ±0.1%.

Temperature Coefficient, for standard resistance range, of

80 ppm/°C in combination with resistance tolerances as

tight as ±0.1%.

Type MG resistors have demonstrated stability of 0.01%

per 1,000 hours in extended load life testing of standard

resistance range values.

This exceptional performance has been proven through

many years of use in equipment that demands the highest

reliability and stability, including TWT amplifiers, X-ray

systems, geophysical instruments, and medical electronics.

Preconditioning for Power and Voltage Ratings

All power ratings and maximum operating voltage ratings

are for continuous duty. These ratings are based on pre-

stress voltage levels applied during the manufacturing

process to provide for stable resistor performance even

under momentary overload conditions.

Maximum operating voltages 60% higher than the values

listed in the table may be specified by adding "-15" to the

model number (Example: MG750-15). Note that overload

and overvoltage ratings do not apply to the "-15" resistors.

Resistance ranges for "-15" resistors shown in the table are

from "-15 Min." to "Standard Max."

Non-Inductive Performance

Most models are manufactured with Caddock's

Non-Inductive Design which uses a serpentine resistive

pattern that provides for neighboring lines to carry current in

opposite directions, thereby achieving maximum cancellation

of flux fields over the entire length of the resistor. This

efficient non-inductive construction is accomplished without

derating of any performance advantages.

Insulation Resistance: 10,000 Megohms, min.

Overload/Overvoltage: 5 times rated power

with applied voltage not to exceed 1.5 times max-

imum continuous operating voltage for 5 seconds

Single-resistor values as high as 10,000 Megohms.

Maximum continuous operating voltages as high as

48,000 volts ("-15" ratings).

Overvoltage capabilities of 150% of standard working

voltages for all models and values, (except "-15" ratings).

Resistance Tolerances from ±1.0% to ±0.1%.

Temperature Coefficient, for standard resistance range, of

80 ppm/°C in combination with resistance tolerances as

tight as ±0.1%.

Type MG resistors have demonstrated stability of 0.01%

per 1,000 hours in extended load life testing of standard

resistance range values.

This exceptional performance has been proven through

many years of use in equipment that demands the highest

reliability and stability, including TWT amplifiers, X-ray

systems, geophysical instruments, and medical electronics.

Preconditioning for Power and Voltage Ratings

All power ratings and maximum operating voltage ratings

are for continuous duty. These ratings are based on pre-

stress voltage levels applied during the manufacturing

process to provide for stable resistor performance even

under momentary overload conditions.

Maximum operating voltages 60% higher than the values

listed in the table may be specified by adding "-15" to the

model number (Example: MG750-15). Note that overload

and overvoltage ratings do not apply to the "-15" resistors.

Resistance ranges for "-15" resistors shown in the table are

from "-15 Min." to "Standard Max."

Non-Inductive Performance

Most models are manufactured with Caddock's

Non-Inductive Design which uses a serpentine resistive

pattern that provides for neighboring lines to carry current in

opposite directions, thereby achieving maximum cancellation

of flux fields over the entire length of the resistor. This

efficient non-inductive construction is accomplished without

derating of any performance advantages.

Insulation Resistance: 10,000 Megohms, min.

Overload/Overvoltage: 5 times rated power

with applied voltage not to exceed 1.5 times max-

imum continuous operating voltage for 5 seconds
