TDK introduces resin electrodes with C0G characteristics for laminated ceramic capacitors

     TDK mass-produces and sells a new series of resin electrodes with C0G characteristics for laminated ceramic capacitors and Mega Caps with metal terminals. As the last powerful means to prevent warping cracks and welding cracks on the substrate, resin electrode series products and stacked products with metal terminals are widely used in the automotive industry and other uses that attach importance to product reliability. For the high permittivity series of X5R, X7R, X8R characteristics, etc., the production corresponding has been made, but the C0G low permittivity series has not been made. Through the promotion of resin electrode series products and overlapping products with metal terminals, C0G characteristics will also be applied in a wider range of fields.

     C0G almost does not cause capacity changes due to temperature changes, nor does it cause capacity reduction due to DC bias, and has very excellent electrical characteristics. But on the other hand, due to the low permittivity, it is difficult to produce capacitors with high electrostatic capacity. TDK combines its expertise in the microrefinement of dielectric materials with thin-layer, multilayer technology to expand rated voltage and electrostatic capacity and achieve the industry's top product lineup.

     Electric vehicles (EVs) are gradually becoming popular. Among them, it is essential to improve the infrastructure of charging equipment and extend the driving distance. It can be said that one of the typical standards for improving infrastructure is contactless power supply. In order to carry out high-power contactless charging efficiently in a short time, it is necessary to lay high-precision resonant circuits under high withstand voltage. With the introduction of TDK's C0G characteristic resin electrode products or volume-based products with metal terminals, effective power transmission and cell miniaturization are achieved simultaneously, thus meeting the high reliability required for on-board devices.

     In addition, in order to use the plug-in mode of electric vehicles to effectively charge on-board chargers (OBCs), the use of LLC harmonic circuit mode has increased, and the high-precision resonant C0G characteristics have attracted much attention. In addition to expanding vehicle-related uses, it is also effective for various circuits and dissimilar capacitors that require high reliability.
