A 1 kΩ NTC (negative temperature coefficient) thermistor in a 5 mm radial dipped-epoxy package. The resistance decreases as temperature increases, making it suitable for temperature sensing, thermal compensation, and monitoring applications. Rugged ceramic construction with tinned copper leads for reliable through-hole soldering.
Key Features
- NTC Ceramic Element – Resistance decreases with rising temperature
- 1 kΩ at 25 °C – Standard reference resistance (±10%)
- Dipped Epoxy Package – Rugged and moisture-resistant
- Through-Hole Mounting – Radial leads with 5 mm pitch
- Wide Temperature Range – −20 to +125 °C

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.
- 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.
