Varistors are voltage-dependent resistors designed to protect electronic circuits from voltage spikes and surges. Commonly used in power supplies, consumer electronics, automotive systems, and industrial equipment, varistors clamp transient voltages to safe levels, safeguarding sensitive components. This category includes metal oxide varistors (MOVs) in various sizes and ratings for AC and DC applications. Amar Radio Corporation offers a wide range of reliable varistor solutions from trusted manufacturers, supporting circuit protection across multiple industries and applications.
