The SCK13104MSY with NTC Thermistors Through Hole RoHS is an electronic component manufactured by TKS. It is designed as an inrush current limiter to protect circuit breakers and other electrical systems from high inrush currents and transients. It consists of an NTC thermistor encapsulated within a metalized polyester sleeve. The thermistor is designed to heat up quickly during an inrush current, and then cools over several milliseconds afterwards. This helps regulate the flow of current and prevents circuit components from being overloaded, and helps to maintain consistent power flow. The component is RoHS compliant, and is designed to be used in through-hole applications.
