The Principles of Varistor Selection
Written By: Teddy Won
Abstract:
A varistor is an electronic component used to suppress transient voltages to protect electronic circuits. The behavior of varistors in a circuit is similar to TVS diodes, but they are entirely different in design, materials, and construction. There are many kinds of varistors on the market suitable for various applications, making choosing the right one to protect a given circuit challenging.
KYOCERA AVX multilayer varistors, with a unique high-energy multilayer construction, provide state-of-the-art overvoltage circuit protection and protection from voltage transients caused by ESD, inductive switching, automotive-related transients, NEMP, lighting, etc. KYOCERA AVX multilayer varistors also provide EMI/RFI filtering in the off-state, which can replace the need for additional EMC capacitors in the system.
