TDK S236 Inrush Current Limiters

TDK S236 Inrush Current Limiters (ICLs) are leaded and coated thermistors that feature kinked tinned copper wires and flame-retardant coating material compliant with UL 94 V-0. These current limiters come with highly stable electrical characteristics and offer rated resistance values from 2.2Ω to 120Ω and a maximum power rating of 2.1W at 25°C. The S236 limiters support maximum current ratings from 1A to 6A, with component dimensions of up to 11.5mm in width, 5.0mm in thickness, and 16.0mm in height. These thermistors include a resistance tolerance of ±20% and are designed for inrush current limiting in switch-mode power supplies and soft-start motors.
