TDK Corporation has announced the development of its TCM06U series of small thin film common mode filters designed for noise reduction in high-speed differential transmission. These filters, measuring just 0.65 x 0.5 x 0.3 mm, began mass production in August 2024.
As digital devices like laptops, tablets, and game consoles continue to offer greater expandability with higher display resolution and increased functionality, their transmission signals have become faster and larger in capacity. This has led to a rise in electromagnetic interference (EMI) from these devices, necessitating measures to mitigate the impact on other devices and prevent the degradation of transmission signal quality. TDK’s new common mode filter addresses this need, offering an effective solution for high-speed differential transmission at high frequencies, supporting the ongoing miniaturization, thinning, and weight reduction of electronic devices.
The TCM06U series is compatible with 20 Gbps high-speed signals, with a cutoff frequency of 20 GHz or higher. It achieves common mode attenuation of 30 dB or more at 10 GHz, effectively controlling high-frequency noise. Additionally, impedance matching within the range of 85 to 90 Ω helps to minimize reflections in high-speed USB lines. The internal coil conductor pattern is crafted using TDK’s proprietary fine patterning technology, which has been refined through the development of the company’s magnetic heads and thin-film production methods.
TDK plans to continue developing small thin-film common mode filters to address the increasing speed of differential transmission lines and contribute to the enhancement of transmission signal quality. These filters are particularly suitable for USB terminals in laptops, tablets, smartphones, STBs, AR/VR/MR devices, game consoles, and other high-speed applications.

Automotive Ethernet filter achieves class IV parasitic capacitance https://www.powerelectronictips.com/automotive-ethernet-filter-achieves-class-iv-parasitic-capacitance/ https://www.powerelectronictips.com/automotive-ethernet-filter-achieves-class-iv-parasitic-capacitance/#respond Wed, 10 Jul 2024 17:41:28 +0000 https://www.powerelectronictips.com/?p=23141 TDK Corporation announces that it has expanded its lineup of the ACT1210E Series (3.2 x 2.5 x 2.5 mm – L x W x T) of common mode filters for automotive Ethernet communication 10BASE-T1S.

TDK Corporation announces that it has expanded its lineup of the ACT1210E Series (3.2 x 2.5 x 2.5 mm – L x W x T) of common mode filters for automotive Ethernet communication 10BASE-T1S. Mass production of this new common mode filter began this month, July 2024.

The new ACT1210E-131-2P-TL00 filter lowers the line-to-line capacitance by approximately 30% compared to conventional products. In the OPEN Alliance EMC test specification for common mode chokes, the part achieves Class IV status with the lowest parasitic capacitance – an industry first. The common mode inductance at 100 kHz is 130 µH, and the rated current is 70 mA.

The communication circuit of 10BASE-T1S has PHY, ESD suppression devices and other electronic components in addition to common mode filters, each of which has its own capacitance. As total capacity increases so does signal wave shape turbulence, which leads to disruptions in normal telecommunications. For this reason, engineers need to select components geared to low capacitance.

To achieve high S-parameters, the new product employs TDK’s proprietary design structure and optimized materials to reduce the impact of signal distortions caused by capacitance and effectively dampen common mode noise. Additionally, the original high-precision automatic winding technology ensures stable quality and high reliability.

TDK has an extensive lineup of common mode filters for automotive applications, including not only filters that are compliant with the currently mainstream CAN, CAN FD, and FlexRay protocols but also compliant with Ethernet protocols, such as 100BASE-T1 and 1000BASE-T1 for telecommunication speeds of 100 Mbps and 1 Gbps respectively. Moving forward, TDK will continue meeting the demands of customers by providing comprehensive product services for common-mode filters for automotive communication.
