Product Overview
The Epoxy-Coated Noise Immune Thermistors (NTC Type NKI) from Amphenol Advanced Sensors are designed to provide reliable temperature sensing in environments with increasing electromagnetic interference (EMI). Featuring component-level EMI protection and a fast time response, these thermistors offer a drop-in upgrade for existing applications, reducing system costs by allowing the use of existing housing designs and eliminating the need for shielded cables. They are EMC-tested to GMW3097 / ISO11452 and are available with a range of conformal coatings. These thermistors are ideal for applications in EV/HEV/PHEV markets, battery temperature sensing, existing automotive upgrades, drive systems, HVAC, and air intake/coolant systems.
