Timing Devices (MEMS Resonator / Crystal Unit / Ceramic Resonator / Oscillator)Ceramic Resonators for Electric Vehicle (EV/PHEV) Devices

What is currently happening in electric vehicle (EV/PHEV) development?

The "CASE" Technological Innovation

"CASE" is the keyword representing the latest trend in the automotive industry. It stands for the technology that is reshaping the automotive industry in a wave that is being called a "once-in-100-years automotive innovation." These four technological developments are proceeding in the automotive industry, and the market is expected to grow further in the future.

Additional functions due to electrification

With the spread of electric vehicles, demand has increased for vehicle-mounted battery management systems (BMS), on-board chargers (OBC), water pumps (WP), and DC-DC converters in the car.

Demand for timing device parts

Demand is increasing for timing device related components in EV/PHEV functions.

Why should you choose Murata's automotive ceramic resonators (CERALOCK)?

Murata's CERALOCK includes built-in load capacitors, which simplify the oscillation circuit design. The built-in load capacitors also assist in reducing PCB board space utilization by incorporating one component as opposed to three.
We have contributed to the safety and security of our customers for decades by meeting the highest reliability requirements for automotive devices.

Compact size and low profile, and reducing number of parts in your design

Designing without external capacitors reduces the board space used by approximately 48% (compared to the 3225 oscillator) allowing for more component implementation.

Contributing to higher reliability for vehicle-mounted devices

Supporting temperatures up to 150°C in compliance with AEC-Q200, CERALOCK has electrical characteristics compatible with CAN and other high-precision communication. Designed for high-temperature environments, it is suitable for use near the engine, battery, and similar locations.

Contributing to safety and reliability

Murata has a proven track record in the global market for automotive applications and has performed IC matching for more than 40,000 cases.
