FAQ

What is the operating temperature range for this thermistor?

The Aqua Rite Thermistor operates reliably from -55 °C to +150 °C, covering most industrial and consumer‑grade environments.

Can I use this thermistor in a high‑frequency switching power supply?

Yes. Its low inductance and stable resistance make it suitable for high‑frequency applications, provided the circuit is designed to accommodate its response time.

How do I determine the correct placement of the thermistor in my circuit?

Place the thermistor in series with the load you wish to protect, typically close to the power entry point. This positioning allows the thermistor to limit the inrush current before it reaches sensitive components.

Is there a warranty or guarantee for these thermistors?

Ametherm offers a one‑year limited warranty covering manufacturing defects, ensuring you receive a replacement if the product fails under normal operating conditions.

Do the thermistors require any special handling or storage?

Store them in a dry, temperature‑controlled environment away from static electricity. No special handling is required during installation beyond standard ESD precautions.
