Metal Oxide Varistor Datasheet

Varistors are voltage dependent nonlinear devices which have electrical characteristics similar to back to back zener diodes.

Metal oxide varistor datasheet.

Cautions and warnings general 1. They are intended for use in a variety of applications from low voltage dc to off line board level protection. When a high current passes through a mov its resistance value decreases and acts as a short. The metal oxide varistor or mov is.

A metal oxide varistor mov is a protection component used in power supply circuits that is powered directly from ac mains it is used to protect the circuit from high voltage spikes by varying its resistance. Specifications are subject to change without notice. The devices have a high current handling high energy absorption capability and fast response. A metal oxide varistor or mov is the blue or orange colored circular component that you can commonly spot on the ac input side of any power supply circuit the metal oxide varistor can be considered as another type of variable resistor that can vary its resistance based on the applied voltage across it.

Typical leakage at 25ºc 25µa maximum leakage 100µa at v m dc. General information the mov 20dxxxk series of 20 mm radial leaded varistor devices protects against overvoltage transients such as lightning power contact and power induction. Metal oxide varistors movs 2020 littelfuse inc. 02 21 20 surface mount multilayer varistors mlvs.

Metal oxide varistors are similar to resistors and has only two leads. L suffix is a low capacitance and energy version. They are composed primarily of z n o with small additions of other metal oxides such as bismuth cobalt magnese and others. Metal oxide varistors movs surface mount varistors ch series ch varistor series rohs description ch series transient surge suppressors are small metal oxide varistors movs manufactured in leadless chip form.

Metal oxide varistors and multi layered varistors. Metal oxide varistors movs surface mount multilayer varistors mlvs mla series notes. The metal oxide varistors offer a choice of varistor voltages from 18 v to 1800 v and vrms voltages from 11 v to 1100 v. 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.

Metal oxide varistor b72230m m401 thermal protective varistor mt30 ppd var pd 2020 01 10 please read cautions and warnings and page 7 of 10 important notes at the end of this document. Tdk electronics metal oxide varistors are designed for specific applications and should not be used for. There is no polarity for these leads and hence can be connected in both directions.
