Selecting the appropriate varistor for a specific application requires careful consideration of various factors. Varistors, also known as voltage-dependent resistors (VDRs), are essential components for protecting electronic circuits from voltage surges and transients.
Understanding the operating voltage, peak current, energy absorption capability, response time, and temperature range of the varistor is crucial. Additionally, considering the mounting method, package size, and environmental conditions ensures optimal performance and longevity.
