Murata WMRAG series MEMS resonator

Murata has developed the world’s smallest 32.768kHz MEMS resonator

Murata IMG-CB Series CO2 Sensors

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.



  • Compact package reduces size applications
  • Low power consumption; 13% less compared to conventional 32,768 kHz resonators
  • Supports embedding into IC's
  • Build-in load capacitance
  • Silicon wafer level package
  • Low ESR 



  • Medical patches
  • Wearables
  • Smart cards
  • Small package modules
