Murata launches ultra compact crystal unit for automotive applications

Murata Manufacturing Co., Ltd.

President/Statutory Representative Director: Tsuneo Murata

Murata Manufacturing Co., Ltd. today announced line-up additions to its XRC family of hybrid crystal timing device specifically for automotive applications. The new products are approximately 40% smaller than the industry norm and measure just 2.5 x 2.0 mm. The XRC series is available with nominal frequencies in the range of 12-24 MHz, and provide a highly accurate high quality clock that is required for automotive electronic control units (ECUs) . Typically used for in-vehicle networks such as CAN*1 and FlexRay*2, the XRC series incorporates a crystal element within a ceramic resonator package structure.

Frequency tolerance is typically ±100pm at 25 degrees C. Operating temperature range is - 40 to + 125 degrees C. The ESR is 30 -50% lower than similar devices available currently on the market in spite of the small package.

This timing device has been developed in conjunction with Murata's new wholly owned subsidiary TEW (Tokyo Denpa) .

Murata will be exhibiting this innovative chip ferrite beads at their booth in "CEATEC JAPAN 2013", which will be held from October 1.

Terminology

*1 CAN: Abbreviation for Controller Area Network. A type of network communications used in automobiles. Currently widely used as a standard on many vehicles.
*2 FlexRay: A type of network communications used in automobiles. Features high communication speeds and real-time responsiveness, making it suitable for use in direct vehicle control (brakes, steering, etc.) .

Applications

  • Engine ECUs
  • Brake ECUs (ABS/ESC)
  • Electric power steering ECUs (EPS) , etc.

*ECU: Electric Control Unit

Parts number

  • XRCHA-F-A series
    ex: XRCHA16M000F0A01R0 (16MHz)
    XRCHA20M000F0A01R0 (20MHz)
