High voltage DSP


•Very small size yet very high DC spark-over voltage
(1000, 1500, 2700, and 3000V)
•The DSP-272M passes 1200VAC - 3sec and the 1000VAC - 1minute test; the DSP-302M passes 1500VAC - 1min withstanding voltage test.
•Quick response for static surge and low limiting voltage.
•Small capacitance and excellent insulation resistance (100M Ω min)
•Stable for repeated static tests and in many environments.
•No polarity.
•No dark effect.
