- Lineup of thin-film common-mode filters expanded with high cutoff frequency types
- Mass production is scheduled to start from August 2012
August 23, 2012
TDK Corporation has developed a new thin-film common-mode filter with the world’s highest cutoff frequency of 10 GHz*, enabling it to efficiently reduce high frequency noise emissions, especially in the 5 GHz band. The common-mode insertion loss peak of the new TCM0806T-060-2P filter is thus 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 Ω 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 from August 2012.
In recent years, digital electronic devices have evolved towards higher performance, multi-functionality, and higher data handling volumes. Consequently, the speed of signal transfer has increased as well. As a result the noise components generated within such a device are generally of a higher frequency as well. At the same time, space is limited and components need to be extremely small and thin for higher mounting density. Since multiple signal paths exist in close proximity in a single device, interference from one may affect the signal in another, leading to signal quality deterioration known as internal contamination.
TDK harnessed its high frequency expertise and proprietary thin-film patterning technology to create a miniature component that features extremely compact and highly precise coil patterns and is thus able to offer the performance demanded in high-speed digital devices.
- * As of August 2012, according to TDK investigations.
- Thunderbolt: A high-speed data interface that is implemented in a serial bus specification for connecting peripheral devices to computers. The maximum transfer speed is rated at 10 Gbit/s, or approximately twice as fast as USB 3.0 and 20 times faster than USB 2.0.
- High-speed interfaces (Thunderbolt, USB 3.0, S-ATA Gen III etc.) for notebook PCs, hard disk drives, solid-state drives (SSD) etc.
