MOV-20DxxxK Series - Metal Oxide Varistor
*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.
Specifications are subject to change without notice.
The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.
Users should verify actual device performance in their specific applications.
Industry Standard Compliance
Standard UL 1449
File Number E313168
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. The metal oxide varistors offer a choice of varistor voltages from
18 V to 1800 V and V
rms
voltages from 11 V to 1100 V.
The devices have a high current handling, high energy absorption capability
and fast response times to protect against transient faults up to rated limits.
