Main Benefits of Metal-Oxide Varistors (MOV Varistors)

Wide Voltage Range: Metal-oxide varistors (MOVs) handle a broad spectrum of voltages, making them versatile for various applications.
High Surge Capacity: MOV varistors can absorb significant energy levels, providing robust protection against high transient currents.
Extended Lifespan: With proper use, metal-oxide varistors offer reliable, long-term protection.
Cost-Effective Protection: MOV varistors provide an economical solution for safeguarding sensitive electronics from voltage surges.

Key Features of MOV Varistor

Working Principle

High Resistance at Normal Voltages: Metal-oxide varistor maintain high resistance under normal operating conditions, allowing the circuit to function without interference.
Rapid Drop to Low Resistance During Surges: When the voltage exceeds the breakdown level, the MOV varistor quickly drops to low resistance within nanoseconds, clamping the surge effectively.
Absorption and Dissipation of Transient Energy: Metal-oxide varistors absorb and convert excess voltage into heat, protecting connected components from damaging.

By clamping transient voltages and diverting harmful currents, MOV varistor safeguards sensitive electronic devices from lightning strikes, power surges, and other voltage spikes. Their ability to switch between high and low resistance based on voltage makes metal-oxide varistors highly effective circuit protection components.
