Available with R25 resistance values of 225\u03a9 or 250\u03a9, it provides precise temperature-to-resistance conversion with tight B-value tolerance. AEC-Q200 qualified for automotive applications, it features Ni-barrier termination for excellent solderability, high long-term stability, and operation from -40\u00b0C to +125\u00b0C.","working_principle":"The NCSA170CT NTC thermistor uses a metal oxide ceramic material whose resistance decreases exponentially with increasing temperature. The relationship follows the Steinhart-Hart equation or simplified B-value equation: R(T) = R0 \u00d7 exp(B \u00d7 (1\/T - 1\/T0)). With a B-value of approximately 4300K, the device provides high sensitivity around room temperature. The small thermal mass of the 0402 chip enables fast thermal response for real-time temperature monitoring.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>Term 1<\/td><td>Bidirectional<\/td><td>Thermistor terminal 1<\/td><\/tr><tr><td>2<\/td><td>Term 2<\/td><td>Bidirectional<\/td><td>Thermistor terminal 2<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Automotive battery temperature monitoring<\/li><li>LED module thermal protection<\/li><li>Motor winding temperature sensing<\/li><li>Industrial temperature compensation circuits<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>NCP15XH223J03RC<\/td><td>Murata<\/td><td>22k\u03a9 0402 NTC alternative<\/td><\/tr><tr><td>NTCG164BH223JT1<\/td><td>TDK<\/td><td>22k\u03a9 0603 NTC<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/11160","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=11160"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/11160\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=11160"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=11160"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=11160"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=11160"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
