TDK-EPC has released a common-mode filter that is claimed to combine common-mode noise suppression and GSM band differential noise suppression in a single component. The TCD0806B-350-2P filter is designed for high-speed differential transmission on mobile industry processor interface lines in smartphones, and conventional mobile phones. The filter measures 0.85x0.65x0.40mm3 and features the company's proprietary thin-film circuit and materials technologies. According to the company, the simultaneous suppression of common-mode and differential-mode noise in the GSM band of 800MHz results in better reception sensitivity for smartphones and other mobile phones. The cutoff frequency of the filter is 3GHz. The typical common-mode impedance is 35Ω and rated current capability is 100mA.
