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

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- Temperature compensation
- Temperature compensation is when a sensor or instrument adjusts its readings to reduce errors caused by changes in temperature. This matters because a sensor's raw output often drifts as conditions warm or cool, so compensation keeps readings more consistent and accurate over time.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
