103 NTC Thermistor Temperature Sensor Code: 19032618

An NTC 103 thermistor is a negative temperature coefficient resistor with a nominal resistance of 10k Ohms at 25°C (where “10” is the base value and “3” represents three trailing zeros multiplier). Its electrical resistance goes down as the surrounding temperature goes up.

Key Specifications

• Nominal Resistance:10kΩ at 25°C
• Temperature Range:-55°C to +125°C (varies slightly by package type like MF52 or MF11)
• B-Value (Beta Constant):Typically 3435K to 3950K (depending on the exact material mix)
• Tolerance:Usually ±1%, ±5%, or up to ±20%
• Response Type:Non-linear resistance-to-temperature curve

Common Uses

• Temperature measurement and compensation in digital multimeters and appliances
• Thermal protection in power supplies and battery packs
• DIY electronics projects using Arduinoor Raspberry Pi controllers
