Manufacturers

Looking for Inrush Current Limiting Thermistors?

The below manufacturers are all of our authorised partners that produce Inrush Current Limiting Thermistors or related products.

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.
