Series of Surge Resistors for PCB mounting are manufactured from a carefully
selected mixture of clays, alumina and carbon. After blending, the material
is pressed to the required shape and then fired, in a controlled atmosphere,
at high temperature.
size and with high surge energy rating, the modular SR Series is designed to
provide the optimum solution to many Power Electronics applications; notably
soft starting the DC link capacitors in Switch Mode Power Supplies.
Inherently non-inductive and capable of withstanding transient high voltage
impulses, the SR Series is similarly effective with respect to overvoltage
protection and crowbar discharge applications.
