MOV-14D121K Description

Short technical summary and product information.

The Bourns MOV-14D121K is a 14mm radial leaded metal oxide varistor (MOV) designed for overvoltage transient protection. It offers a typical varistor voltage of 120V at 1mA DC, with a voltage tolerance of ±10%. The device can handle a maximum peak current of 4.5kA (8/20µs) and absorbs up to 32J of energy.

 

Key electrical specifications include a maximum clamping voltage of 200V at 50A peak (8/20µs), maximum continuous AC voltage of 75V, and maximum continuous DC voltage of 100V. The varistor has a typical capacitance of 2040pF at 1kHz and a fast response time of 10ns to 25ns.

 

The MOV-14D121K is housed in a Disc 14mm package with through-hole mounting. It is RoHS compliant per Directive 2015/863. This varistor is suitable for protecting sensitive electronic equipment from voltage transients caused by lightning, power contact, or power induction.
