Inrush Current Limiters (ICL) : 422 - Page 22

Inrush Current Limiters (ICL) are essential for managing high initial currents that occur when electrical devices are first powered on. These components protect circuits by temporarily limiting the current flow, preventing potential damage to components such as capacitors and transformers.

ICLs are commonly used in power supplies, motor drives, and battery chargers, where they help to extend the lifespan of both the power source and the device itself. These devices typically feature positive temperature coefficient (PTC) thermistors, which increase resistance as they heat up, thus limiting the inrush current.

Notable manufacturers like Ametherm, EPCOS, and Murata offer a wide range of ICLs designed for various applications, ensuring reliability and efficiency. By integrating ICLs into your design, you can enhance system stability and longevity, making them invaluable components in modern electronic designs.
