Metallized Polypropylene Film Capacitors
For example, consider two of the main purposes of capacitors in electric vehicles: to prevent ripple currents from reaching back to the power source, and to smooth out DC bus voltage variations. Capacitors are also vital in protecting semiconductors – originally thyristors, but now usually IGBTs.
TDK Corporation (TSE: 6762) presents ModCap™ − a modular capacitor concept for DC link applications. The newly developed power capacitors are available for rated voltages of 1100 V to 2300 V and cover a 365 µF to 2525 µF capacitance range. The rated currents between 105 A and 180 A are type-conditioned with all types designed for 5 kA recurrent pulse currents. The maximum permitted hot spot temperature is 90 °C.
Fast oxidisation is a common issue related to high temperatures and the presence of oxygen during the convection reflow or wave soldering processes. The oxidisation may induce some degradation of metal surface and its environmental robustness, thus impacting the components and the electronic hardware lifetime.
TDK Corporation (TSE:6762) announces the development of a miniaturized thin-film power inductor in an IEC 2012 case size that can handle higher currents compared to conventional products. The low-profile TFM201208ALD power inductor measures in at 2.0 x 1.25 x 0.8 mm and is available with a rated inductance of 1.0 µH.
Inside the presentation, we will cover mainly 2 topics:
1st one will consist to address packaging material, I mean Ceramic versus Organic packages,
2nd one will address relevant Quality standards with NX proposal Quality flows and pricing level versus Quantity.
