Crystal UnitsThe Advantages of Murata's Crystal Units

Murata has been providing ceramic resonators (CERALOCK®) to the market for over forty years, to use as a reference clock in microcomputers and other devices.

In order to support devices requiring a clock with higher frequency precision than ceramic resonator's, using our unique technology, Murata and Tokyo Denpa jointly developed miniature and highly reliable crystal units.

We have started supplying products for consumer market since 2009, and for automotive market since 2013.

The products, jointly developed with Tokyo Denpa, have been adopted more as HDD/SSD/USB and other storage devices started to use small crystal units due to the increased need for speed and capacity.

Later, Murata's crystal units began to be adopted for use in NFCs with smart phone's features of personal authentication / electronic money payment sophisticated.

The adoption of small crystal units is still increasing due to the growing demand for small devices in AV/PC/automotive equipment and Wi-Fi communications equipment as well as the market growth of wearable and smart phone peripheral devices equipped with BT/BLE communication features that connect to smart phones.

Murata's crystal units use a package structure which differs from typical crystal units.
While regular crystal units use a ceramic substrate with a cavity structure, Murata's crystal units use a structure which combines a metal cap with a planar ceramic substrate, which has a ceramic resonator with a proven track record extending back many years.

Using the highly versatile planar ceramic substrate and metal cap allows us to reduce the material costs compared with conventional crystal units, achieve stable supply, and increase production.

We have an integrated system from crystal stone production, design, manufacturing with our own original equipment, to worldwide sales network.

Introducing this system to our own manufacturing leads us to open up new fields and provide new value to customers.
