NKI Series NTC EMI Protected Thermistors

Amphenol Advanced Sensors' thermistors have a built-in capacitor for RF decoupling

Image of Amphenol Advanced Sensors NKI Series NTC Noise-Canceling ThermistorsAmphenol Advanced Sensors' NKI series has a built-in capacitor for RF decoupling which provides electromagnetic interference (EMI) and self-heating protection. With increasing complexity of electric systems and density of electronic components in modern vehicles, conventional NTC thermistor sensors are vulnerable to stray EMI causing self-heating.

Thermometrics has developed a noise immune NTC thermistor with an integrated radio frequency (RF) decoupling function, providing protection from EMI at the component level over a wide frequency range.
