Three-terminal MLCC attains industry-leading capacitance in a compact package

Murata has extended its line-up of high-Q-rated MLCC. Designed for high-frequency module applications such as those used in cellular communication infrastructure, the GJM022 series expands the world’s smallest high-Q capacitor with a voltage rating of 100V.

To facilitate high-speed 5G communication, designers must include numerous high-frequency outputs and the required power amplifiers. This increased component count has emphasised the need for the modularisation of wireless communication circuits.

The company has developed the series in response to the growing necessity for compact but high-performing capacitors. It has used state-of-the-art thin-layer forming and high-precision laminating technologies to produce an advanced and miniaturised capacitor that does not compromise on performance – exhibiting the outstanding high-Q and low-loss performance required by the latest applications.

With a size of 0.4mm × 0.2mm LW, the new series allows electronic engineers to overcome packaging limitations while retaining optimal performance. The high temperature guarantee further helps with this initiative by supplying designs with greater freedom over positioning. This permits reliable long-term operation, even near hot components that radiate heat, such as power semiconductors.

The series is an excellent option for various applications, such as impedance matching and DC cutting applications within RF modules for base stations. In such implementations, the high-Q value and low ESR contribute to improving power amplifier efficiency and lowering power consumption.

“5G is represents a significant performance improvement over previous generations of cellular communications, but for engineers to take advantage of this exciting technology in their designs they require the support of high-quality passive components,” said Nakagawa Hidetoshi, general manager at Murata. “With the GJM022/100V series we have listened to the market’s technical demands and met them head on.”
