TDK S236 Inrush Current Limiters

TDK S236 Inrush Current Limiters (ICLs) comprise leaded and coated NTC thermistors with kinked tinned copper wires, flame-retardant coating compliant with UL 94 V-0, and stable electrical characteristics. These thermistors offer resistance values from 2.2Ω to 120 Ω, with a maximum power rating of 2.1 W at 25°C and ±20% resistance tolerance. The S236 current limiters are used to control high initial current flow in electrical circuits, helping limit inrush current in switch-mode power supplies and soft-start motors.
