Murata hits record inductance value in 0402 size inductor

Murata has recently developed a film-type high-frequency chip inductor which boasts the world's largest inductance value of 39nH.

The use of the ultra-miniature0402-size components is gaining momentum due to the increasing number of components used in smartphones and other compact mobile devices. The company has mass-produced the conventional LQP02TN series and also the LQP02TQ series that has high Q value characteristics, as high-frequency inductors of ultra-miniature size.

The company recently added four items between 22nH and 39nH to the line-up of its 0.220nH conventional LQP02TN series. By further developing their unique fine-forming technology that is the most significant feature of the LQP series, they have realised the world's largest inductance value of 39nH in the 0402 size. As a result of this addition to the line-up of the LQP02TN series, the current line-up covers the range between 0.2nH and 39nH and consists of 59 items, a world record in which we take pride. Regarding the deviation of the inductance value as well, we can cope with narrow deviations of 0.1nH (0.24.2nH) and 3per cent (4.339nH).

Murata's extensive line-up and ability to provide inductance values with narrow deviations improve the number of degrees of freedom in circuit design employing the ultra-miniature 0402 size and also contribute to further miniaturisation and functional enhancement of electronic devices such as smartphones. Going forward, we will strive to further widen the available range of inductance values, improve the Q characteristics, and promote the development of further miniaturisation.
