The B57234S0220M000 is a inrush current limiter NTC thermistor manufactured by TDK. It is a self-regulating, solid-state device that limits rapid increases in current flow at startup. It provides stable startup power, protecting the system from momentary overloads and greatly reducing hot starts, motor hum, and wear and tear on mechanical and electrical components. This thermistor contains a resistance value of 234/22 ohms at 25°C, has a resistance tolerance of ±10%, and a maximum rated power of 0.2 watts. It has a M-type construction, made of a highly heat-resistant, ceramic material that ensures exceptional insulation and reliability.
