HEL-14D330K 14mm Metal Oxide Varistor (MOV) 33V 1kA Surge Protection

The HEL-14D330K is a 14mm Metal Oxide Varistor (MOV) designed to guard low-voltage DC and AC circuits against dangerous voltage spikes, surges, and transients. With a 1kA maximum surge current rating and a clamping voltage of just 65V at 10A, it acts as a fast-responding voltage clamp that absorbs transient energy before it can damage sensitive downstream components — making it an essential protection device in SMPS, consumer electronics, automotive circuits, and microcontroller-based boards.
