MOV 20D511 Metal Oxide Varistor

MOV 20D511 Metal oxide Varistor for circuit protection against voltage spike

MOV 20D511 is a 20 mm radial leaded varistor devices protects against over voltage transients such as lightning, power contact and power induction. 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, also known as MOVs are one of the most common types of varistors. They are voltage dependent, nonlinear devices that provide transient suppression.

A Metal Oxide Varistor (MOV) is used in power supply circuits as a protection component. MOV are similar to resistors and has only two leads, there is no polarity and can be connected in both directions. MOV is basically used to protect the circuit from high voltage spikes.

MOV have a high current handling, high energy absorption capability and fast response times to protect against transient faults up to rated limits.

DNA Solutions deal in retail as well as in bulk quantity. For bulk quantity feel free to contact us. DNA Solutions has large collection of various values of Metal Oxide Variastors (MOV). Check our complete collection of MOV.
