The electrification of automobiles is advancing toward autonomous driving, and accordingly noise countermeasures in automobiles become increasingly important. This time, we will introduce an automotive noise suppression filter MHF/MDF series that has unique features as compared to general chip beads.
The MHF series achieves a high impedance in the MF and HF bands ranging from 300 kHz to 30 MHz used in radios, etc., and has an excellent noise suppression effect. Furthermore, the MDF series is a product with excellent DC bias characteristics of impedance so that an excellent noise suppression effect can be obtained even when used in a power supply line.

TDK Corporation (TSE:6762) presents three new B8272* series of compact EPCOS SMT common-mode chokes specially developed for low-voltage applications. They sustain voltages of up to 48 V AC (50/60 Hz) and 80 V DC, and continuous currents between 1.8 A and 19 A at an ambient temperature of 40 °C. The new series cover a range of inductance values between 0.59 mH and 5.6 mH.

TDK Corporation presents a new series of current-compensated EPCOS double-ring core chokes for the suppression of common-mode interferences.

With the spread of cloud computing and smartphones and the launch of 5G in 2020, the amount of data that moves on the internet is increasing as high-volume video and game data is added to existing documents, images, and sound data.
In addition, technologies are evolving, exemplified by AI, and a digital transformation (DX) is taking place as a result of the use of big data and the internet of things (IoT). To support these advances, however, large numbers of high-performance servers that can process large volumes of data will be needed. In conjunction with the increased performance of processors and various types of ICs, higher clock speeds of power supply ICs on server boards, high current power saving, miniaturization, noise countermeasures in data lines, and surge countermeasures have become urgent issues. Here, we introduce TDK products for addressing and solving these problems including the VLBU series of ferrite power inductors compatible with the high-efficiency needs of VR13 and VR14 applications, the FS series of DC-DC converters with embedded μPOL™, solutions using the ALT series of pulse transformers and ALC series of common mode filters and chokes, and chip varistors and ceramic transient voltage suppressors used for surge protection.

Automakers are incorporating more multifunctional capabilities into automobiles as they seek to make autonomous driving a reality. Electronic control units (ECUs) for advanced driver assistance systems are consuming more power, and the latest trend is toward ECU integration—installing an ECU close to the engine room or other working part.
For these reasons, the number of electronic devices and components built into cars these days is on the rise, and the reliability of the electronic components used in the electronics is having a growing impact on the reliability of the vehicle overall.

Aggregate earth leakage currents can often cause RCDs (residual current devices) to trip at their threshold. As a result, RCDs are either not usable or only with substantial additional outlay.

TDK Corporation (TSE:6762) has extended its range of EPCOS power line chokes to include six new types. The new components are available in three different core shapes with different rated currents and inductance values, delivering great design flexibility.

TDK Corporation announces that it has reengineered and improved the EPCOS LeaXield™ active leakage current filter, a unique solution that is able to minimize earth leakage currents in converter-based drive systems.

The individual components in variable-speed drives cause earth leakage currents that cumulatively result in the tripping of the RCD. By using the upgraded EPCOS LeaXield™ active leakage current filter, these earth leakage currents be drastically reduced.
