NTC Type NKI Epoxy-Coated Noise Immune Thermistors 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. Thermometrics has developed 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. Applications Features EV/HEV/PHEV Markets NTC element-level EMI protection Battery Temperature Sensing Fast time response Existing Automotive - Upgrade Drop-in upgrade for existing applications Drive Systems Reduced system cost: - Retrofit to use existing housing designs HVAC - Eliminate shielded cables Air Intake / Coolant EMC-tested to GMW3097 / IS011452 Range of conformal coatings available Amphenol Advanced SensorsNoise Immune Thermistor (NKI) Specifications NKI Resistance Values B Value R25 Material Code Code Code Code Code 25/85C System R25C 1% R25C 2% R25C 3% R25C 5% R25C 10% K 500 2 3540 1% NKI 501C2*1 NKI 501C2*2 NKI 501C2*3 NKI 501C2*5 NKI 501C2*10 500 2A 3627 1% NKI 501C2A*1 NKI 501C2A*2 NKI 501C2A*3 NKI 501C2A*5 NKI 501C2A*10 500 7 3977 1% NKI 501C7*1 NKI 501C7*2 NKI 501C7*3 NKI 501C7*5 NKI 501C7*10 1000 2 3540 1% NKI 102C2*1 NKI 102C2*2 NKI 102C2*3 NKI 102C2*5 NKI 102C2*10 1000 2A 3627 1% NKI 102C2A*1 NKI 102C2A*2 NKI 102C2A*3 NKI 102C2A*5 NKI 102C2A*10 1000 7 3977 1% NKI 102C7*1 NKI 102C7*2 NKI 102C7*3 NKI 102C7*5 NKI 102C7*10 2000 2 3540 1% NKI 202C2*1 NKI 202C2*2 NKI 202C2*3 NKI 202C2*5 NKI 202C2*10 2000 2A 3627 1% NKI 202C2A*1 NKI 202C2A*2 NKI 202C2A*3 NKI 202C2A*5 NKI 202C2A*10 2000 7 3977 1% NKI 202C7*1 NKI 202C7*2 NKI 202C7*3 NKI 202C7*5 NKI 202C7*10 2700 1 3977 0.75% NKI 272C1*1 NKI 272C1*2 NKI 272C1*3 NKI 272C1*5 NKI 272C1*10 5000 4A 3435 1% NKI 502C4A*1 NKI 502C4A*2 NKI 502C4A*3 NKI 502C4A*5 NKI 502C4A*10 5000 1 3977 0.75% NKI 502C1*1 NKI 502C1*2 NKI 502C1*3 NKI 502C1*5 NKI 502C1*10 10000 4A 3435 1% NKI 103C4A*1 NKI 103C4A*2 NKI 103C4A*3 NKI 103C4A*5 NKI 103C4A*10 10000 5 3740 1% NKI 103C5*1 NKI 103C5*2 NKI 103C5*3 NKI 103C5*5 NKI 103C5*10 10000 1 3977 0.75% NKI 103C1*1 NKI 103C1*2 NKI 103C1*3 NKI 103C1*5 NKI 103C1*10 12000 5 3740 1% NKI 123C5*1 NKI 123C5*2 NKI 123C5*3 NKI 123C5*5 NKI 123C5*10 30000 8 3977 1% NKI 303C8*1 NKI 303C8*2 NKI 303C8*3 NKI 303C8*5 NKI 303C8*10 50000 8 3977 1% NKI 503C8*1 NKI 503C8*2 NKI 503C8*3 NKI 503C8*5 NKI 503C8*10 Other values available upon request.
