As the safety and comfort of automobiles increases, more electronic devices are being used in vehicles. Electronic circuits have signal lines and power supply lines, and both require noise countermeasures. TDK’s common-mode filters are characterized by a diverse lineup of products for specific applications including product groups that pursue compact size or a low profile and product groups that adopt an independent terminal structure to meet the harsh environmental conditions of automotive applications. This chapter introduces common-mode filters for power supply lines.

The CUR 4000 is a single-axis contactless magnetic-field sensor for galvanically isolated DC and AC current measurements.
This article clearly describes and explains information valuable for our customers related to the features of TDK's CUR 4000 current sensor.

TDK Corporation (TSE:6762) has extended its range of coupled inductors to include the new EPCOS series B82472D6*. The nine series types cover an inductance range of 2 x 2.2 µH to 2 x 47 µH and are designed for maximum rated currents of 1.1 A to 4.3 A. The RoHS-compliant chokes are certified in line with AEC-Q200 and feature high saturation currents of up to 7.95 A. The magnetically shielded inductors have dimensions of just 7.3 x 7.3 x 4.8 mm and are designed for a wide temperature range of between -55 °C and +150 °C. Depending on the type, the chokes offer very high coupling factors of the two windings, from 97 to 99 percent.

TDK Corporation (TSE:6762) presents the EPCOS aluminum electrolytic capacitors B43706* and B43726* series with screw terminals. The new components are designed for rated voltages between 400 V DC and 500 V DC and cover a capacitance range of 820 µF to 15,000 µF.

TDK Corporation (TSE:6762) has extended its range of TVS (transient voltage suppression) diodes characterized by their extremely low capacitance values for bidirectional overvoltage protection to include the ULC series (Ultra Low Clamping & Capacitance).

TDK Corporation (TSE:6762) presents its new B32320I* series of compact cylindrical DC-link capacitors for mounting on PCBs. They are designed for voltages of 450 V DC to 1300 V DC and cover a capacitance range of 6.5 µF to 260 µF.

ThermoFuse® Varistors are used for overvoltage protection with an additional thermal element as safety feature.
Over the last years the fail safe functions got more popular and as a result the variety of thermally protect varistors increased on the market which resulted in many designs for different sizes and surge capabilities.
This article will show the benefits and features of TDK ThermoFuse® Varistor vs Standard Varistors.

In conjunction with advances in automotive technology, it is become necessary to quickly convey large volumes of data, and increasing the speeds of automotive networks has become increasingly important. And in conjunction with increases in the communication speeds of automotive networks, signal quality and EMCcountermeasures have become increasingly important.As a result, it is necessary to select common mode filters/chokesthat comply with the OPEN Alliance standards.This document describes TDK's ACT1210L series of common mode filter/choke for automotive Ethernet use.

TDK presents a new series of EPCOS power capacitors for DC link applications. The new capacitors are available for rated voltages of 700 V DC to 2000 V DC.

TDK Corporation has released tiny high-power TVS diodes for ESD protection, extending its portfolio of components for bidirectional overvoltage protection of I/O interfaces.
