B72205S0251K101 Varistor: metal-oxide; THT; 250VAC; 320VDC; 390V; 400A; -40÷105°C

The B72205S0251K101 is a robust metal-oxide varistor (MOV) designed for transient voltage surge suppression in a wide range of electronic applications. This through-hole (THT) device is specifically engineered to protect sensitive components from voltage spikes and surges, ensuring the reliability and longevity of electronic equipment. It features a maximum continuous operating voltage of 250VAC and 320VDC, making it suitable for both AC and DC circuits. The varistor voltage is 390V, providing a clamping voltage that effectively limits voltage surges. With a surge current capability of 400A, it can withstand significant transient events. The operating temperature range of -40°C to 105°C ensures reliable performance in diverse environmental conditions.

This metal-oxide varistor is designed to protect electronic circuits from voltage transients caused by lightning strikes, inductive load switching, and electrostatic discharge (ESD). When a voltage surge exceeds the varistor voltage (390V), the varistor rapidly decreases its resistance, diverting the excess current away from sensitive components. This clamping action prevents damage to downstream circuitry, ensuring the continued operation of the equipment. The 400A surge current capability allows it to handle substantial transient events, providing robust protection against voltage surges. The through-hole mounting configuration simplifies installation and ensures a secure connection to the circuit board.
