Combined filter saves space

TDK-EPC presents a new common-mode filter that combines common-mode noise suppression and GSM band differential noise suppression in a single component. The TDK TCD0806B-350-2P is designed for high-speed differential transmission on MIPI lines in smartphones, conventional mobile phones and other mobile devices.

Measuring 0.85 by 0.65 by 0.40mm³, the product features proprietary thin-film technologies to handle not only conventional common mode noise but also differential mode noise. The simultaneous suppression of common-mode and differential mode noise in the GSM band is said to result in improved reception sensitivity for smartphones and other mobile phones. Moreover, manufacturers can reduce the number of components needed, thus enabling smaller mobile devices.
