Краткое описание:
MOV VARISTOR STANDARD
Дополнительная информация
High-energy radial-leaded metal oxide varistor provides transient voltage suppression for surge protection circuits. The device is based on an 18 mm E-series disc with straight leads and is rated for continuous operation at 120 Vac or 160 Vdc. Its varistor voltage range is 170 V to 207 V at the classification test current, and it clamps to 320 V at a 75 A 8/20 µs pulse. Surge ratings are 9000 A for a single 8/20 µs pulse and 6000 A for two pulses, with 70 J energy handling and typical 1600 pF capacitance at 1 kHz.
