Overvoltage Suppression Fast Response VDR 25mm Zinc Oxide Varistor Resistor 25D101K 100V For Surge Protection
Description
The 25D 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 18KA (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
■ Wide operating voltage (V1mA) range from 18V to 1800V
■ Symmetrical V-1 characteristics (Non Polarity)
■ Fast responding to transient over-voltage
■ Large absorbing transient energy capability
■ Low clamping ratio and no follow-on current
■ Meets MSL level 1, per J-STD-020
■ Operating Temperature:-40 ~ +85 ℃
■ Storage Temperature:-40 ~ +125 ℃
Applications
■ Transistor, diode, IC, thyristor or triac semiconductor protection
■ Surge protection in consumer electronics
■ Surge protection in industrial electronics
■ Surge protection in electronic home appliances, gas and petroleum appliances
■ Relay and electromagnetic valve surge absorption
General Characteristics
No Radioactive Material
Body: Nickel Plated
Leads: Surface-mount, Axial Devices: Tin Plated
Devices with No Leads: Nickel Plated
