TDK to Showcase Innovations in Power Technologies at APEC 2019

TDK Corporation (TSE: 6762) will present its latest power solutions in booth 811, APEC 2019, March 18-20, in the Anaheim Convention Center, Anaheim, California.

TDK’s suite of products for engineers includes a variety of solutions to meet the growing and diverse demand for power technologies in the automotive, mobile, robotics and industrial equipment industries and beyond. The offerings complement the company’s existing roster of leading electronic components.

The exhibition will showcase TDK, EPCOS and TDK-Lambda products, including:

Ceramic capacitor series in modular flex-assembly technology: Proven CeraLink^® has extended their product offering to include modular flex-assembly (FA) technology. This space-saving CeraLink FA series connects two, three or ten identical capacitors in parallel over the same terminals in order to increase the capacitance. Due to their low parasitic effects, CeraLink capacitors are ideally suited for converter topologies on the basis of fast-switching semiconductors such as GaN or SiC. Voltage overshoots when switching are significantly lower than with conventional capacitor technologies.

Stacked MLCCs with high capacitance and low ESR: The CA series of vertically stacked MEGACAP MLCCs combine high capacitance and low ESR. The capacitors are suitable for the resonant circuits of wireless and plug-in charging systems, for example, for industrial vehicles and robots. They can also be used in smoothing and decoupling applications in industrial equipment.

Soft-termination MLCCs with low ESR: The CN series features terminal electrodes with a conductive resin layer that provides high mechanical robustness to protect against board flexure. At the same time, the MLCCs offer a low ESR that is comparable to that of conventional MLCCs. Soft-termination MLCCs, which are able to withstand the stress from board flexure, are an effective way to prevent short circuits when used in battery lines. TDK has achieved the low terminal resistance values by applying the conductive resin layer only where the terminal electrode comes into contact with the PCB. These MLCCs are suitable for battery lines in automotive and industrial robot applications, where they help to improve system reliability.

Extremely robust rugged AC filter capacitors with extended range: The B32754* to B32758* series of EPCOS AC filter capacitors cover a range of voltages from 250 V AC to 400 V AC and offer capacitances of between 1 µF and 70 µF. The capacitors comply with IEC 61071: 2007 and are extremely robust, even at high humidity. The capacitors are suitable for demanding applications in industrial electronics. These include output filtering for power supplies, frequency converters for drives and renewable energy, or UPS systems.

High-voltage contactors with current capabilities up to 500 A: The HVC series of high-voltage contactors has been expanded with the new HVC300 and HVC500 types with current capabilities of 300 A and 500 A, respectively. Their gas-filled switching chamber ensures that arcs are safely and quickly extinguished when the current is switched off. The HVC series is especially suitable for use in battery management systems and DC charging stations in e-mobility applications. Further applications include DC traction systems, photovoltaic, energy storage systems, and uninterruptable power supplies (UPS). These applications require fast and reliable disconnecting from the DC source.

Compact fuse-protected overvoltage protection varistors: The EPCOS ThermoFuse™ family of overvoltage protection varistors has been extended with the compact NT14 and NT20 series. These new components feature a footprint that fits into existing circuit board layouts. ThermoFuse varistors are uniquely designed disk varistors that are connected in series with a thermally coupled fuse and are therefore intrinsically safe. If the varistor overheats, the patented thermal fuse trips and isolates the varistor from the grid with unrivalled dependability. This prevents any potential damage on the PCB or to components located near the varistor and increases the reliability of the equipment to be protected.

High-current SMD power inductors with superior DC bias characteristic: The SPM series power inductors are the metal composite type wire-wound inductors that have the coils integrally molded with metallic magnetic powder. Compared to ferrite-base wire-wound inductors, the SPM series inductors realize larger current, lower Rdc, smaller size and superior DC bias characteristic. In addition, they ensure low magnetic flux leakage and are effective as a means to suppress acoustic noise of the coil.

Miniaturized thin-film metal power inductors suitable for ADAS applications: The TFM252012ALVA thin-film metal power inductors can be connected directly to a 12 V car battery while maintaining small dimensions. In today’s automobiles, electronic control units are increasingly being installed to electrify various control functions and to implement in-vehicle information communication, autonomous driving, and other functions. The number of automotive ECUs necessary for implementing ADAS and thereby the number of inductors for power circuits used in these units have been increased. However, because the number of parts has been increasing while mounting space is limited, there is a growing demand for small-size electronic parts featuring high performance and reliability.

Effective noise countermeasure components for use with Class-D amplifiers: Class-D amplifiers, which are used in devices such as smartphones and audio equipment, have the advantages of being compact and highly efficient, but crucially require countermeasures against noise generated by their high-speed switching. TDK has an extensive lineup of noise suppression filters, inductors for LPFs and chip varistors, which provide effective noise countermeasures while ensuring high sound quality and without affecting signals.

30W wireless charging coils with superior performance efficiency: TDK has partnered with a wireless power system solution provider to provide 30W power delivery solutions up to 30 mm of non-metallic building material. The solution uses TDK Rx & Tx coils, and offer an unique power delivery system which is not affected by low-E glass coatings. With a superior performance efficiency greater than 80%, these products support one-to-one charging and power delivery. Applications include telecom, 5G FWA, residential and enterprise CPE, security cameras, factory automation, and more.

Compact, conduction cooled 504W rated AC-DC power modules: The conduction cooled TDK-Lambda PFH500F-28 AC-DC power modules are ideal for a variety of applications including COTS (Commercial-Off-The-Shelf), power amplifiers, LED displays and test equipment. The PFH500F-28 series utilizes GaN semiconductors, bridgeless power factor correction, synchronous rectification and digital control, enabling efficiencies of up to 92%.

Faraday Semi, a TDK group company, will also exhibit its recent innovations in micro DC-DC converters at TDK’s APEC 2019 booth.
