Protect vulnerable downstream filter capacitors and power semiconductors from destructive startup surges with premium NTC Current Limiters from Al-Hekmh Electronics. These specialized negative temperature coefficient thermistors present a high electrical resistance when cold, safely absorbing and suppressing the massive initial inrush currents that occur during equipment turn-on.
As current flows through the device, its internal temperature rises, causing its resistance to drop to a negligible level for efficient, low-loss steady-state operation. They provide an indispensable, cost-effective safety shield for switch-mode power supplies (SMPS), industrial motor starters, heavy transformers, and consumer electronics mainlines.
