Description

The GA10K3A1A is part of TE Connectivity’s BetaCURVE series of Negative Temperature Coefficient (NTC) thermistors. Its bead element is soldered to 32AWG alloy leads and encapsulated in a thermally conductive Stycast epoxy resin, which provides mechanical protection, environmental sealing, and excellent thermal coupling for fast response times. The alloy lead wires are specifically chosen to minimize thermal conductivity errors, enhancing measurement accuracy.

This thermistor is engineered for high-reliability applications requiring precise temperature tracking. Its tight tolerance and stable Beta constant make it suitable for direct integration into temperature compensation circuits, custom probe assemblies, and precision instrumentation where consistent performance over the -40°C to 125°C range is critical. The through-hole radial package is ideal for robust, permanent installations on printed circuit boards.

Key Features

  • Precision Interchangeability: ±0.1% resistance tolerance at 25°C allows for direct replacement without individual calibration.
  • High Stability Beta Value: A Beta constant (B25/85) of 3976K ensures predictable and repeatable resistance-temperature characteristics.
  • Durable Epoxy Encapsulation: The bead is protected by a thermally conductive Stycast epoxy coating, offering mechanical robustness and environmental sealing.
  • Optimized Thermal Design: Alloy lead wires reduce parasitic thermal conduction, improving measurement accuracy of the sensed environment.
  • Proven Reliability: Designed for long-term stability and rapid thermal time response in demanding applications.
  • Versatile Integration: Radial through-hole leads facilitate straightforward PCB mounting for permanent installations.

Applications

Frequently Asked Questions

What is the tolerance of the GA10K3A1A thermistor's resistance at 25°C?

The GA10K3A1A offers a tight interchangeability tolerance of ±0.1% for its 10 kΩ nominal resistance at 25°C. This precision allows for direct replacement in circuits without requiring individual calibration, making it suitable for high-accuracy instrumentation.

How do I interface this NTC thermistor with a microcontroller like an Arduino?

Interface is straightforward using a voltage divider circuit. Connect the thermistor in series with a precision reference resistor (e.g., 10 kΩ) between your microcontroller's supply voltage (3.3V or 5V) and ground. Measure the voltage at the midpoint with an analog input pin. Use the Steinhart-Hart equation or a lookup table with the provided Beta value (3976K) to convert the reading to temperature.

What is the Beta (B) value, and how is it used?

The Beta value (B25/85 = 3976K) is a material constant that characterizes the resistance-temperature relationship of the NTC thermistor. It is used in simplified equations or lookup tables to calculate temperature from a measured resistance, providing accurate results over the specified operating range without requiring full Steinhart-Hart coefficients.

Can this thermistor be used for surface temperature sensing, or does it need a probe?

While its epoxy-coated bead and alloy leads are designed for reduced thermal shunting, for optimal surface temperature measurement, it is recommended to integrate the GA10K3A1A into a custom probe assembly. This ensures good thermal contact and isolates the bead from the PCB's thermal mass, improving response time and accuracy.
