Murata Manufacturing Co., Ltd.

Murata Manufacturing Co., Ltd.- Audio

Murata Manufacturing Co., Ltd., founded in 1944, is a global leader in the design and manufacture of electronic components, with its headquarters in Nagaokakyo, Kyoto Prefecture, Japan. The company's core business revolves around advanced ceramic materials and their applications, including capacitors, inductors, filters, sensors, and wireless communication modules. Murata's product portfolio is anchored by its world-renowned multilayer ceramic capacitors (MLCCs), with series such as the GRM and GCM families, which are essential in virtually all electronic devices. In addition, the company offers a broad range of inductors (LQM, LQH series), EMI suppression filters, and noise suppression components. Murata is a major supplier of connectivity solutions, including Type 1YN and Type 1DX Wi-Fi/Bluetooth modules, enabling IoT and automotive applications. Its timing devices, such as crystal oscillators and ceramic resonators (e.g., CSTCE series), provide precise frequency control. The company also produces MEMS-based sensors, including gyroscopes (SCC2000 series) and accelerometers, for automotive safety and industrial systems. Power supply modules and DC-DC converters further expand its footprint in energy-efficient designs. Murata holds the number-one global market share in MLCCs, estimated at around 40%, and is a top-three player in SAW filters and connectivity modules. Renowned for its vertical integration and proprietary ceramic material science, Murata continuously pushes miniaturization and performance boundaries, serving industries from smartphones to electric vehicles.
