Inrush Current Limiting Thermistors

Inrush current limiting thermistors are used for protecting the circuit against occasional current spikes significantly higher than normal operating current, which could otherwise damage the equipment. At Rhopoint Components we offer a range of current limiting resistors from industry-leading manufacturer Ametherm, with various sizes, resistance and maximum steady-state current options available. The Ametherm thermistors compare favourably with traditional inrush current limiters, offering lower current density, faster reset time, wider temperature range and virtually no derating.

Please be advised that due to the ongoing supply issues with raw materials affecting the global electronics industry, as well as an increase in orders received by our manufacturing partners, a large number of products are facing increased lead times in recent months. For the latest lead time and stock availability, please contact one of our engineers who will be happy to discuss lead times further and the potential for alternative parts.
