🔧 NTC 5D-15 Thermistor – High Quality Inrush Current Limiter
The NTC 5D-15 Thermistor is a high-performance, temperature-dependent resistor designed to protect electrical circuits by limiting inrush current. This component is widely used in AC and DC power supply systems, SMPS circuits, LED drivers, chargers, and transformer-based equipment. Rafiq Electronics brings you the original and reliable 5D-15 thermistor suitable for DIY projects, repairs, and professional use.
📌 What is NTC 5D-15?
NTC stands for Negative Temperature Coefficient, meaning its resistance decreases as temperature increases.
The 5D-15 model indicates:
-
5Ω cold resistance
-
15mm disc diameter
This makes it ideal for medium-power devices where surge protection is necessary.
