NTC thermistors tout precise temperature measurement
TDK Corporation announces two new series of narrowly toleranced EPCOS NTC thermistors in EIA 0402 and 0603 SMD case sizes. These components have a rated resistance of 10 kΩ in tolerance classes ±1 percent, ±3 percent and ±5 percent. The narrow tolerances were achieved with a new production technology and 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 percent across the board. With their short response time, the new NTC thermistors enable fast and precise temperature measurement across a wide range. These SMD NTC thermistors are available in two series: the automotive series, qualified to AEC-Q200 and suitable for applications up to +150oC; and the standard series for applications up to +125° C. Applications include electronic control units, air conditioning systems, and temperature monitoring of batteries and charging systems. In addition, the temperature management of high-performance LEDs, which are rapidly replacing conventional halogen and xenon headlights, is also a growing area. Other diverse applications are found in communications equipment, including charge monitoring of batteries in mobile devices and temperature monitoring of LCDs, amplifiers, hard disks and digital cameras.
