High-Q chip inductor

22 August 2012 Passive Components

The new HKQ0603W from Taiyo Yuden is a high-frequency multilayer chip inductor (0,6 x 0,3 x 0,3 mm) series, which achieves the very high Q value. It is designed for impedance matching applications in the high-frequency circuits of small mobile devices such as smartphones for which the adoption of LTE next-generation communications standards is progressing and multiband capabilities are increasing.

With a typical Q value of 48 for the HKQ0603W 2N7 in the 1,8 GHz frequency range, compared to the company’s conventional product, the HKQ0603U 2N7 (with a typical Q value of 41), it has been possible to achieve an improvement of 15% or more.
