Radial Lead Varistor (MOV)
The UNS3220- 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 1KA
(8/20μs pulse) to protect against high peak surges, including
indirect lightning strike interference, system switching
transients and abnormal fast transients from the power
source.
Wide operating voltages ranging from 11Vrms to
460Vrms
Operating Temperature: -55℃~ +125℃
Storage Temperature: -55℃~ +150℃
Electric strength: ≥2.5kVRMS
Fast response time of less than 25ns, instantly clamping
the transient over voltage.
Insulation Resistance: > 100MΩ
High surge current handling capability.
High energy absorption capability.
Low clamping voltages, providing better surge protection
White package design without shadow in LED lighting
application
SMD mountable disk varistors, suitable for lead-free
reflow / wave soldering
Power supplies for telecommunication systems
Surge protection in industrial electronics.
Protection for LED circuits
Relay and electromagnetic valve surge absorption.
