Radial Lead Metal Oxide Varistor (MOV)
14D Series
Description
The 14D series radial leaded varistors provides an ideal circuit
protection solution for lower DC voltage applications by
offering higher surge ratings than ever before available in such
small discs.
The maximum peak surge current rating can reach up to 6KA
(8/20
μs
pulse) to protect against high peak surges, including
indirect
lightning
strike
interference,
system
switching
transients and abnormal fast transients from the power
source.
Features
u
u
u
u
u
Wide operating voltage (V1mA) range from 18V to 1800V
Fast responding to transient over-voltage
Large absorbing transient energy capability
Low clamping ratio and no following-on current
Meets MSL level 1, per J-STD-020
Applications
u
Transistor, diode, IC, thyristor or triac semiconductor
protection
u
u
u
Surge protection in consumer electronics
Surge protection in industrial electronics
Surge protection in electronic home appliances, gas and
petroleum appliances
