Murata’s MEMS resonators are piezoelectric elements that function as mechanical resonators to generate a constant frequency.

MEMS technology was used to realize the world’s smallest size resonator with very low ESR characteristics that is currently unachievable by quartz crystal resonators. Murata’s MEMS resonators achieves excellent frequency accuracy and stable temperature characteristics without the use of active elements to correct the initial frequency and frequency shift by temperature. This helps customers reduce both power consumption and mounting space.

MEMS resonators are well suited for use in medical patch type devices, smart cards, modules with communication functions, wearable devices, wireless earphones and other small and low-profile devices, and embedding in ICs such as microcomputers and real-time clocks.

Murata Icon X Three Main Features

  • Space saving
This product realizes an ultra-compact chip scale package (CSP) that incorporates the necessary load capacitance for the oscillation circuit. This enables a reduction in the total oscillation circuit space needed, which helps to reduce the final set size.

In addition, the open space can also be used to increase the battery size or add other functions.

Ceramic Resonator

  • Embedding supported  
The wafer level chip scale package (WLCSP) uses silicon materials that have high affinity when mounting with a semiconductor IC chip made of the same material. This enables embedding in the IC.
Transfer molding and wire bond mounting can also be supported. 
 



  • Low power consumption
The low ESR characteristics can be utilized to lower the IC gain.
This enables a reduction in the current consumption of the oscillation circuit and the power consumption of the overall set.
