TDK Corporation (TSE: 6762) has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V coils with a power consumption of 6 W.

TDK Corporation (TSE: 6762) presents with the B40640B* and B40740B* series hybrid polymer capacitors with a very high ripple current capability increased by up to 29 per cent compared to preceding types. The ripple current capability is now up to 35 A (20 kHz, 125 °C). The new types are designed for a rated voltage of 63 V, cover a capacitance range from 390 µF to 720 µF, and offer an extremely low ESR value. For example, with a cup size of 16 mm x 30 mm (D x H) and an ambient temperature of 20 °C, an ESR of 3.9 mΩ at 20 kHz can be achieved. Even at an operating temperature of -40 °C, the ESR is just 5.4 mΩ.

In e-mobility, the temperature of all system units needs to be constantly monitored. The high currents result in losses with a corresponding generation of heat arising, in particular, at contacts. TDK has now developed a special-purpose high-voltage resistant temperature sensor for connectors.

In the automotive field, CPUs and FPGAs for systems that require advanced image processing, such as onboard ADAS ECUs and autonomous ECUs, need to operate at high speed and require high drive current in conjunction with the increasing performance and functionality of systems. Also, in the ICT field, power supply configurations that support higher current required for devices that need huge amounts of power such as servers. There is a trend towards higher operating speeds and higher currents in the power supply lines of systems with increased performance and functions as described above. At the same time, power supply structures that maintain the nominal voltage within narrow tolerance ranges, which have decreased in conjunction with processor miniaturization, are also required.

TDK's transparent conductive silver [Ag] alloy film (FleClear®) is a versatile material that has numerous use cases. Many of these uses require making direct electrical contact to the film's low resistance conductive surface in order to adequately perform the targeted applications. The following Application Note provides an overview of FleClear®, a step-by-step procedure of attaching an metal electrode, a list of needed equipment, along with the recommended materials to attach copper bus bars to the conductive surface. Additionally, where important, the suppliers and the respective numbers, are also listed..

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.
