Current electronic control units (ECUs) in automobiles use mainly differential signal communications with twisted-pair wires to simplify and reduce the weight of vehicle wiring harnesses.
Among these, the CAN (Controller Area Network) communication system is used for communications that require extremely high reliability such as driving, turning, and stopping.

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 Corporation (TSE: 6762) presents the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics. There are four models in the series, with basic winding insulation of a working voltage of 500 VRMS and reinforced insulation of 300 VRMS. The turns ratio is between 1:0.76 and 4:1, depending on the model.

TDK Corporation (TSE: 6762) has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types. The inductance values of the new B82559B*A016 series, which replaces the former B82559A*A016 series, extend from 1.0 µH to 30 µH, and their saturation currents range from 10.3 A DC to 40.4 A DC at 25 °C.

NFC is an abbreviation of Near Field Communication; it is a type of short-range wireless communications.
NFC is a function that can perform data communications and authentication when two NFC-compatible devices are brought close together, and adoption in smart phones has been growing rapidly in recent years.
Increased use in peripheral devices including wearable terminals, such as smart watches, has also been observed.
NFC is used in many situations including cashless payment and authentication of connections with peripheral devices, and it is expected to be used for even more diverse applications as we move towards a touchless society.
This article introduces the main components used in NFC circuits: NFC antenna, magnetic sheet, LC filter inductor, single-end circuit balun, and electric double-layer capacitor (EDLC/supercapacitor).

TDK Corporation (TSE: 6762) presents two new series of ThermoFuse® varistors, which are equipped with monitor outputs and integrated thermal protective components for overvoltage protection.
The MT25 series (B72225M*) currently covers a voltage range from 150 VRMS to 385 VRMS, and its maximum surge current capability is 20 kA at a pulse form of 8/20 µs, according to IEC 61643-11. With dimensions of 25 x 28 x 14 mm, the completely encapsulated protective components feature a particularly compact design. Their monitor outputs are optionally available with or without electrical isolation.

TDK Corporation presents a new range of Open Mode chip varistors for electronic automotive assemblies that are directly connected to the battery. The new chip varistors offer reliable protection against transient surge voltages according to ISO 7637-2, and meet the failsafe requirements according to the VW standard VW 80808. Even when subject to excessive bending stress, short-circuits are avoided, which is particularly important for unswitched battery terminals (e.g. terminal 30).

TDK Corporation presents the new B58703M1103A* temperature sensor − specially developed for demanding E-mobility applications, which call for high long-term stability. The NTC sensor is designed for a temperature range of -40°C to +150°C, whereby a temporary load of up to 200°C is permitted. At 25°C the rated resistance is 10 kΩ with a B25/100 value of 3625 K and a tolerance of ±1 percent.

In electric vehicles, temperature monitoring of all power components is a basic requirement for ensuring the safety, reliability and longevity of the entire system. Robust TDK and EPCOS NTC temperature sensors available in a wide range of different designs are key components for this task.

TDK Corporation has extended its product range of hybrid-polymer aluminum electrolytic capacitors, and now offers two series with an axial design. The B40600* / B40700* series is designed for rated voltages of 25 V and 35 V. These cover a capacitance range from 780 µF to 2200 µF. Capacitors in the 63 V voltage class, with capacitance values from 390 µF to 720 µF, are available with the B40640* / B40740* series.
