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)
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Temperature compensation
- Temperature compensation means the sensor adjusts its readings to reduce errors caused by changes in water temperature. This matters for field monitoring because ponds, rivers, and tanks can vary in temperature throughout the day and across seasons.
