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.

[Application Note]
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.

[Product Overview]
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.
