TE Connectivity GA10K4A1A NTC Thermistor, Bead, BetaCURVE Chip, 10 kΩ

The GA10K4A1A has a nominal resistance of 10 kΩ at the standard reference temperature of 25°C. This specific variant features a tolerance of ±0.5%, though the series is available in tighter tolerance options down to ±0.1°C for higher precision applications.

The Alloy 180 leads are specifically chosen for their low thermal conductivity. This design minimizes the 'stem effect,' where heat is conducted away from or towards the sensing bead along the leads, which can introduce measurement errors. This ensures more accurate readings of the ambient or fluid temperature.

This NTC thermistor is rated for continuous operation from -40°C to +125°C. It offers a fast thermal response, with a time constant (tau) of less than 1 second when immersed in a liquid, making it suitable for dynamic temperature monitoring in fluids and other media.

The NTC chip is coated with a thermally conductive epoxy for efficient heat transfer and then fully encapsulated in a robust Stycast resin. This construction protects the sensitive element from mechanical stress, moisture, and chemical exposure, ensuring long-term stability and reliability in harsh environments.
