In contrast to traditional heating elements for conventional 12V onboard power supplies, TDK's recently-released EPCOS PTC heating elements are designed for the considerably higher voltages found in EV batteries. The rated voltages of these heating elements range from 200 to 500V, producing surface temperatures of up to 250°C. Depending on design, these heating elements are suitable for safe operation at up to 1000V.

  Suitable for deposition processes, ROVs, ATE systems and general laboratory and industrial use, 600W programmable DC power supplies have been released by TDK. The devices, which expand the company’s Z+ series, are offered with output voltages of up to 160, 320 or 650VDC. 

A fully revised data book on EPCOS aluminium electrolytic capacitors with crew terminal, snap-in, axial and single-ended connections, has been released by TDK. The B43704/B43724 and B43705/B43725 series of screw-terminal capacitors, which feature a significantly improved current capability, are included within the book.

Two series of leaded MLCCs, which are halogen-free according to IEC 61249-2-21, have been released by TDK. The FG series consists of commercial-grade devices, while the FA series consists of automotive-grade devices. To support the design of environmentally friendly applications, the MLCCs do not use halogen as a flame retardant in the external resin coating.

TDK has released a multilayer low-pass filter for LTE and other next-gen high-speed wireless communication systems. Thanks to thinner ceramic layers, finer conductor lines and an optimised internal electrode design, the DEA071910LT-4003B1 achieves a miniaturised footprint of 0.65x0.5mm and a slimmer insertion height of just 0.3mm (form factor 06505).

The UK Intellectual Property Office has approved TDK-Lambda UK’s power supply heatsink arrangement patent application. To dissipate heat, power supply designers utilise a variety of components, including surface mount and leaded parts. These components, however, require different cooling arrangements.

The UK Intellectual Property Office has approved TDK-Lambda UK’s power supply PFC controller patent application. The requirement for industrial power supplies to limit harmonic currents has existed for many years, and in Europe the standard is defined by EN 61000-3-2.

Designed for use in automotive electronics, the CLF6045NI-D series of wirewound SMD power inductors has been released by TDK.
