NTC 4.7D2-13 Thermistor
The NTC 4.7D2-13 is a Negative Temperature Coefficient (NTC) thermistor designed primarily for inrush current suppression in AC and DC power circuits. When power is first applied, the thermistor presents a relatively high resistance that limits the initial surge current flowing into capacitors and other components. As current passes through the device, it heats up and its resistance decreases significantly, allowing normal circuit operation with minimal power loss.
This thermistor is widely used in switching power supplies, LED drivers, industrial control systems, battery chargers, UPS systems, and consumer electronics. Its compact design, reliable performance, and simple installation make it an effective solution for extending component life and protecting circuits from damage caused by excessive startup current.
