BETATHERM NTC Thermistor, 10K3A542I, 10kΩ

The BETATHERM 10K3A542I is a high-precision BetaCurve interchangeable NTC thermistor, engineered for accurate temperature measurement and sensing. This bead-type thermistor is soldered to 30AWG Kynar insulated wire, providing reliable electrical connection, and the entire unit is coated with a protective layer of black Stycast 2850FT epoxy for durability and environmental resilience.

Designed for stability, it offers a nominal resistance of 10kΩ at +25°C. The device maintains a tight tolerance of ±0.2°C across the 0°C to +70°C range, ensuring consistent and reliable readings in critical applications. Its thermal characteristics include a Beta value (25/85) of 3976K and a dissipation constant of approximately 2.0mW/°C.

A key feature is its rapid response time, with a thermal time constant in liquid of just 1.3 seconds when moving from +25°C to +75°C. This makes it ideal for applications requiring fast and accurate temperature detection. The operating temperature range is extensive, from -40°C to +125°C, allowing for deployment in both harsh and controlled environments.
