Harnessing its proprietary thin-film patterning technology, TDK created a miniature component that features extremely compact and highly precise coil patterns and is able to offer the performance demanded in high-speed digital devices.
The common-mode insertion loss peak of the TCM0806T-060-2P filter is much higher than that of existing common-mode filters, which achieve their best noise suppression in the range from several hundred MHz to 2.5 GHz. The high cutoff frequency of the new filter ensures that no signal degradation occurs when the filter is used in communication circuits for high-speed interfaces such as Thunderbolt, USB 3.0, and Serial-ATA (Gen III), making the thin-film common-mode filter suitable for sophisticated electronic devices with high signal transfer speeds.
The new component, which offers a typical impedance of 6 � at 100 MHz, measures in at 0.85 x 0.65 x 0.40 mm3 (EIA case size 0806). Mass production is scheduled to start this month.
