■ Features
| • |
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 Ωmin) |
| • |
Stable for repeated discharge test conditions and environmental
fluctuation. |
| • |
No polarity. |
| • |
No dark effect. |
| • |
This series is recognized under UL 1414, UL1449, CSA and
T ÜV. |
Typical applications
• AC Adaptor.
• Antenna-circuit of TV, VCR.
• Communication line. (If T, R~GND AC withstanding test is required.)
