Metal Oxide Varistors (MOVs) use zinc oxide that has been heat treated and formed into a disc.  The zinc oxide disc acts as a non-linear resistor, clamping the voltage at a given level.
Mos

Electrostatic Discharge (ESD) Devices protect against the discharge of electrostatic energy using an array of miniature Transient Voltage Suppressors.  ESD surges are typically small, so the p

Positive Thermal Coefficient devices, also known as ¡®re-settable fuses¡¯, provide over-current protection for electrical and electronic devices. They function using conducting strips of metal imbedd

Thryistor Surge Suppressors (TSS) are one kind of semi-conductor surge absorbers.
They feature:
 • Precise control over break-down voltages (VBR), offering superior tolerance
