Murata has increased the lineup of its industry-leading chip thermistor family by adding a new automotive grade series of compact NTC (negative temperature coefficient) chip thermistors. The NCP****0S** series features operating temperature between -40 and +150 degC and will be used in high temperature environments such as engine control circuitry.
The NCP****0S** series features wide resistance value and size ranges to maximise design flexibility. The automotive grade parts are available in two case sizes. The NCP15**0S* series is in 0402 case size, including 22 different resistance values between 1.5kOhm and 470kOhm. The NCP18**0S* series is in 0603 case size and features extended resistance range with 21 available values between 100 Ohm and 470 kOhm.

NCP****0S** series thermistors are suitable for use in practically every part of an automotive electronics system. For example, monitoring temperature to protect ICs and devices such as power MOSFETs in the engine control unit (ECU), ABS, EPS (electric power steering) and alternator control systems. Temperature monitoring is also required for normal operation of devices such as LCDs, DC-DC converters, DVD drives and fiber optic transmitters for MOST. Further examples include temperature-compensation circuitry for various sensors, or monitoring the temperature inside the inverter (ballast) unit in the headlamps.
