TDK Corporation (TSE:6762) presents the new B78302A* series of compact EPCOS transformers with innovative E5 cores for ultrasonic applications. It comprises three types with transformation ratios between 1:1:10.8 and 1:1:15.3. Depending on the type, the new transformers in SMD design offer inductance values between 2 mH and 4 mH and are suitable for frequencies from 50 kHz to 300 kHz. The AEC-Q200 qualified components have very compact dimensions of only 8.1 x 7.0 x 7.0 mm and are shielded by a counter-winding for better interference suppression. The permissible temperature range is between -40 °C and +125 °C.

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. This article introduces the structure, features, and application of these products, and other information that helps you in an easy-to-understand way.

TDK has a lineup of multilayer chip varistors that protect equipment for malfunction and failure due to ESD (electrostatic discharge), and we have long contributed to solving customer ESD problems.
Recently, however, although multilayer chip varistors have been effective in the past, they have been unable to provide sufficient protection as customer devices have become smaller, lighter, and more sophisticated.
To investigate the cause of this problem, we conducted ESD tests assuming the miniaturization of customer equipment.

The TFM series of power inductors consists of compact, thin inductors developed with the skillful application of the thin-film processing techniques acquired by TDK throughout its past. By using metallic magnetic materials with high saturation magnetic flux densities, these products have furthermore achieved the outstanding DC superimposition characteristics required of power inductors. This article clearly describes and explains valuable information for our customers related to the products in the TFM series, including their structures, features, and uses.

TDK Corporation (TSE:6762) presents the B3271*H* series, new EPCOS film capacitors for DC link applications that feature high energy and power density. The capacitors are rated for voltages from 500 V DC to 1600 V DC, offer capacitance values from 0.47 µF to 170 µF and are suitable for a maximum operating temperature of up to 105 °C. At a rated voltage and operating temperature of 70 °C, the typical life of the rugged, self-healing and RoHS-compliant capacitors is 95,000 hours.

TDK Corporation (TSE:6762) presents the new B58101A0109A* (HP100) series of heat pump sensors for measuring the refrigerant temperature indirectly via the pipes' surface temperature. The NTC-based sensors are specifically designed to meet automotive requirements. Standard for pipe diameters of 12.8 mm, this clip-on design can operate in harsh environments from -40 °C to +150 °C and is water immersion resistant for up to 500 hours. The response time is less than 7 s. The new AEC-Q200 qualified sensors offer a high dielectric strength of 1250 V AC for 10 s, an important criterion for use in EVs. A low temperature tolerance of ±0.3 K at a nominal temperature of 85 °C ensures high control accuracy.

TDK Corporation (TSE:6762) presents the EPCOS E13EMHV series of compact SMT transformers with high dielectric strength for a wide range of DC-DC converter topologies. The isolation distances comply with IEC 60664-1, 61558-2-16 standard, achieving a high working voltage of 1000 V DC. Transient overvoltages of up to 2500 Vpeak are permitted. The high dielectric strength between the primary and secondary sides is 3000 V AC (50 Hz, 60 seconds).

High energy, reliable and volumetric efficient inverters are essential to reducing emissions of vehicles based on 48 V technology. DC-link capacitors can significantly contribute to this target by reducing parasitic losses and increasing thermal efficiency. High inverter powers can be theoretically achieved with multiple capacitor connections. However, a high number of parallel-connected parts also increase the complexity of the system stability. In the field of Aluminum Electrolytic Capacitors, the Hybrid Polymer technology offers higher ripple current densities by a factor of, e.g., 5x compared to standard Liquid Electrolyte technology. By applying the Hybrid Polymer technology to the large axial capacitor can sizes, with solid mechanical construction and special thermal dissipation feature, a compact DC-link solution with a reduced amount of capacitor and minimized thermal escalation risk through stable and efficient thermal design can be achieved.

TDK, a world leader in material technologies, manufacturing and electronic components, has recently developed and released a state-of-the-art, Qi compliant planar wireless power coil utilizing a unique copper patterning technology that provides multiple end-user benefits. The Wireless Power Consortium [WPC] has designated this new coil as MP-A28, while the corresponding TDK part number is WCT38466-N0E0SST01. TDK’s “pattern coil” technology allows for intricate coil patterns that cannot be duplicated by the use of discrete wires and yields tight trace width and gap control normally associated with the finest etching processes and technologies. Also unique to TDK’s technology, is the ease and flexibility to accurately change the copper trace thickness, depending on the application requirements, which is not available by traditional copper coil techniques.
