Information
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.

Information
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.
