Metal oxide varistors movs 2020 littelfuse inc.
Metal oxide varistor datasheet.
When a high current passes through a mov its resistance value decreases and acts as a short.
02 21 20 surface mount multilayer varistors mlvs.
Typical leakage at 25ºc 25µa maximum leakage 100µa at v m dc.
There is no polarity for these leads and hence can be connected in both directions.
They are intended for use in a variety of applications from low voltage dc to off line board level protection.
Metal oxide varistors movs radial lead varistors la varistor series should transients occur in rapid succession the average power dissipation is the energy watt seconds per pulse times the number of pulses per second.
Specifications are subject to change without notice.
Metal oxide varistors mov data sheet features wide operating voltage v 1ma range from 18v to 1100v fast responding to transient over voltage large absorbing transient energy capability low clamping ratio and no follow on current meets msl level 1 per j std 020 operating temperature 40 105.
