TDK B57153S Disc NTC Thermistor, 4.7Ω, 3A

The TDK B57153S Disc NTC Thermistor is a high-quality electronic component designed for precise temperature sensing and inrush current limiting applications. This negative temperature coefficient (NTC) thermistor features a robust 8.5mm disc construction, offering reliable performance in a compact form factor.

With a nominal resistance of 4.7Ω at 25°C, this thermistor is engineered to handle a maximum steady-state current of 3A. Its primary function is to protect circuits by presenting a high initial resistance that decreases as its temperature rises, effectively limiting inrush current to sensitive components like motors, transformers, and power supplies during startup.

Crafted from advanced semiconductor materials, the TDK B57153S series is renowned for its stability, fast response time, and durability. The component's compact dimensions make it suitable for integration into densely populated printed circuit boards (PCBs) across a wide range of industrial and consumer electronics.

Key Applications

This thermistor is an essential part of power management and protection circuits. It is commonly used for temperature compensation, temperature measurement, and as a critical safety device to prevent damage from sudden current surges.
