DSS-302M has received recognition to EN132400 through T
V. Report No J9750615.
High DC spark-over voltage in spite of compact size (2types; 2700, 3000V) .
DSS-272M and DSS-302M each correspond to 1200volts rms 3seconds or
1000volts rms 1minute and 1500volts rms 1minute AC withstanding voltage
tests respectively.
Quick response for surge voltage and low limiting voltage.
Small capacitance and excellent insulation resistance (100M
min)
Stable for repeated electrostatic test conditions and environmental fluctu-
ation.
No polarity.
No dark effect.
This series is recognized under UL 1414, UL1449, CSA and TV.
AC Adaptor.
Antenna-circuit of TV, VCR.
Communication line. (If T, R~GND AC withstanding test is required.)
The first two digits are significant,
and the third is number of zeros.
