3 Pin Transistor Outline Hermetic Resistor Network
The three pin TO-18 package is suitable for single resistor
hermetic packaging with case and lid grounded for electrical
isolation. This unique package may also be used to provide a
voltage divider, but the user is cautioned that the center tap must
go to ground.
Review data sheet "7 Technical Reasons to Specify Bulk
Metal Foil Resistor Networks."
3 pins on a 0.100" pin circle pin 3 case grounded.

NOTES:
1. These networks utilize Vishay Bulk Metal
Foil resistor
chips V5X5 and V15X5 or VTF15X10 Thin Film chips.
2. The V5X5 and V15X5 chips have maximum resistance
values of 10K and 33K respectively in Bulk Metal
Foil
and 500K in VTF15X5 Thin Film chips.
