MEMS Resonator

Ceramic Resonator
Frequency:32.768kHz

Size (LxWxT):0.9 x 0.6 x 0.3(in mm)

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.

When considering replacement from a crystal resonator, note that the load capacitance value differs for crystal resonators and MEMS resonators.

Murata Icon X Main Feature

  • High reliability under high temperatures
The device supports high reliability especially in high temperature conditions because it does NOT utilize organic adhesives inside of the package.
For this reason, this device can be used in applications where good high-temperature performance is required, such as in industrial equipment and lighting.

*High Accelerated Stress Test
**Pressure Cooker Test


  • 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.
