## Description

A 47 kΩ NTC (Negative Temperature Coefficient) thermistor in a compact 5 mm radial package. NTC thermistors decrease in resistance as temperature rises, making them ideal for temperature sensing, thermal protection, and compensation circuits. Dipped in epoxy for durability, this through-hole component features tinned copper leads with 5 mm pitch for easy breadboard and PCB mounting. Key Features NTC Ceramic Element – Resistance decreases predictably with rising temperature Epoxy-Dipped Radial Package – Rugged and reliable for long-term use Through-Hole Mounting – 5 mm lead pitch, tinned copper legs Wide Application Range – Temperature sensing, thermal runaway protection, compensation circuits Specifications Resistance at 25 °C – 47 kΩ ±10% Diameter – 5 mm Temperature Coefficient – Negative (NTC) Operating Temperature – From −20 °C Thermal Dissipation – 6 mW/°C Maximum Power – 500 mW DC Current Rating – 20 mA Lead Pitch – 5 mm Mounting – Through-hole, solder legs Ideal For Temperature measurement and monitoring circuits Thermal protection for transistor amplifier stages Temperature compensation in analogue circuits Arduino and microcontroller temperature sensing projects Package Contents 1× NTC Thermistor 47 kΩ (5 mm radial)
