TDK Corp.’s two new series of narrowly toleranced EPCOS NTC (negative temperature coefficient) thermistors in EIA 0402 and 0603 surface-mounted device (SMD) case sizes feature a rated resistance of 10 kΩ in tolerance classes ±1%, ±3%, and ±5%. Applications for the components include electronic control units, air-conditioning systems, and temperature monitoring of batteries and charging systems. According to the company, the narrow tolerances were achieved with a new production technology and rugged glass passivation, which also ensures high reliability and degradation stability. With their short response time, the new NTC thermistors enable fast and precise temperature measurement across a wide range, claims the company. The devices are available in two series: the automotive series, which is qualified to AEC-Q200 and suitable for applications up to +150°C (+302°F); and the standard series, which is suitable for applications up to +125°C (+257°F).
