## Description

An epoxy-coated precision NTC thermistor with a 10kΩ resistance at 25°C and ±1% accuracy. The resistance decreases as temperature rises and increases as it cools, making it straightforward to measure temperature with a simple voltage divider circuit. The epoxy coating allows the thermistor to be used in damp environments such as air conditioners, water lines, and outdoor weather stations. The PVC-coated leads are rated up to 105°C. An additional 1% 10kΩ resistor is included for use as a voltage divider partner or calibration reference. Key Features 10kΩ at 25°C, ±1% – Precision NTC thermistor for accurate temperature measurement B-Constant 3950 – Well-characterised response curve Epoxy Coated – Sealed for use in damp and wet environments PVC-Coated Leads – Rated up to 105°C Includes 10kΩ Resistor – Ready to build a voltage divider circuit Specifications Resistance at 25°C – 10kΩ ±1% B-Constant – 3950 Type – NTC (Negative Temperature Coefficient) Coating – Epoxy Lead Insulation – PVC, rated to 105°C Ideal For Arduino and CircuitPython temperature sensing projects Weather stations and environmental monitoring Water temperature measurement HVAC and air conditioning systems Package Contents 1× 10kΩ NTC thermistor (epoxy coated) 1× 10kΩ 1% resistor Resources Temperature-to-resistance lookup table (PDF) Thermistor tutorial – Arduino & CircuitPython
