Inrush Current Limiters (ICL)
Inrush Current Limiters (ICL) are circuit protection components used to reduce high startup current when electronic equipment is first powered on. They help protect power supplies, rectifiers, capacitors, switches and downstream circuits from excessive current stress. They are widely used in power adapters, industrial power supplies, motor drives, chargers, LED lighting, consumer electronics, automation equipment and embedded systems.
This category includes NTC inrush current limiters, thermistor-based ICL components, power supply inrush limiters, motor startup current limiters and related overcurrent protection devices. These components are commonly selected based on resistance value, maximum steady-state current, energy rating, operating temperature, response behavior, package type and application requirements.
TomatoElec supplies original Inrush Current Limiters from recognized manufacturers such as TDK, EPCOS, Vishay, Murata, Amphenol, Ametherm, Littelfuse, Bourns, Panasonic and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
