Murata commences mass production of Hybrid Crystal Resonator

Murata Manufacturing Co., Ltd. has commercialized and commenced mass production of "Hybrid Crystal Resonator," quartz crystal unit, jointly developed with Tokyo Denpa Co., Ltd.

Murata has combined Tokyo Denpa's high quality quartz crystal element technology and their production technology to jointly develop quartz crystal units "Hybrid Crystal Resonators" as a timing device responding to the market demands.

The market for this device is latest HDD with new bus interface such as SATA and USB. Here the expensive crystal oscillator is replaced by this low cost but of nearly same precision hybrid crystal resonator

Murata said it has already has strong hold of ceramic resonators market in automotive and consumer applications, now its aiming to expand into HDD market where relatively high precision is required.

As per joint deal, Tokyo Denpa provides quartz crystal elements, and Murata handles production and sales of quartz crystal units.

Key advantages, and features of Hybrid Crystal Resonator series called XRCGA series are,

More inexpensive compared with quartz crystal units
Higher precision compared with ceramic resonators, while the initial frequency precision for ceramic resonators ranges between a few hundred to a few thousand ppm, that of a Hybrid Crystal Resonator is approximately 100 ppm.
Complies to RoHS directive, being lead-free
Accommodates lead-free solder mounting

Specifications:
Nominal frequency: 24 to 48 MHz
Initial frequency deviation: ±100 ppm
Temperature characteristics: ±50 ppm
Operational temperature range: -30 to 85 Deg C
