NTC thermistors
4 September 2013
Passive Components
New from TDK are two series of narrowly toleranced EPCOS NTC thermistors in EIA 0402 and 0603 SMD case sizes. The components feature a rated resistance of 10 kΩ in tolerance classes ±1%, ±3% and ±5%. These narrow tolerances were made possible thanks to a new production technology and a rugged glass passivation, which also ensures high reliability and degradation stability.
The slope of the characteristic curve (B value: 3455 K) has a narrow tolerance of ±1% across the board. Therefore, and thanks to a short response time, the parts enable fast and precise temperature measurement across a wide range.
The new NTC thermistors are offered in two series: the automotive series, which is qualified to AEC-Q200 and is suitable for applications up to +150°C, and the standard series for applications up to +125°C. They are suitable for use in automotive electronics, such as in electronic control units and air conditioning systems, as well as for the temperature monitoring of batteries and charging systems.
The temperature management of high-performance LEDs, which are increasingly replacing conventional halogen and xenon headlights, is also a fast-growing application area. There are also diverse applications in communications equipment. These include the charge monitoring of batteries in mobile devices and the temperature monitoring of LCDs, amplifiers, hard disks and digital cameras.
