Thermometrics Epoxy-Coated Type NKI of Noise Immune Thermistors are newly developed, consisting of a noise immune NTC thermistor with an integrated radio frequency (RF) decoupling function, providing protection from electromagnetic interference (EMI) at the component level over a wide frequency range.
With increasing complexity of electric systems and density of electronic components in modern vehicles, conventional NTC thermistor sensors are vulnerable to stray electromagnetic interference causing self-heating.
Applications
- EV/HEV/PHEV Markets
- Battery Temperature Sensing
- Existing Automotive - Upgrade
- Drive Systems
- HVAC
- Air Intake / Coolant
Features
- NTC element-level EMI protection
- Fast time response
- Drop-in upgrade for existing applications
- Reduced system cost:
- Retrofit to use existing housing designs
- Eliminate shielded cables
- EMC-tested to GMW3097 / IS011452
- Range of conformal coatings available
