TDK Co., Ltd. (President: Ishiguro Nao) has released a series of ceramic electrode products and a new series of Mega Caps with metal terminals that will be mass-produced and sold in December 2016. . As a last resort to prevent substrate warpage cracks and weld cracks, resin electrode series products and laminated products with metal terminals are widely used in the automotive industry and other applications that emphasize product reliability. For the high-capacitance series of X5R, X7R, and X8R characteristics, mass production has been made, but the C0G low-capacitance series has not been matched. Through the advancement of resin electrode series products and laminated products with metal terminals, C0G characteristics will also be applied in a wider range of fields.
C0G hardly causes capacity change due to temperature changes, and does not cause capacity drop due to DC offset, and has excellent electrical characteristics. On the other hand, it is difficult to produce a capacitor having a high electrostatic capacity due to a low permittivity. TDK combines the fine-grained technology of dielectric materials with thin-layer and multi-layer technology to expand the rated voltage and electrostatic capacity and achieve the industry's top product lineup.
Electric vehicles (EVs) are beginning to gain popularity. Among them, it is essential to improve the infrastructure of charging equipment and extend the cruising range. It can be said that one of the typical standards for improving infrastructure is non-contact power supply. In order to efficiently perform high-power non-contact charging in a short time, it is required to arrange a high-accuracy resonant circuit at a high withstand voltage. The introduction of TDK's C0G-featured resin electrode products or stacked products with metal terminals simultaneously realizes efficient transmission and miniaturization of the unit, thus meeting the high reliability required for on-vehicle devices.
In addition, in order to effectively charge the on-board charger (OBC) by the plug-in method of the electric vehicle, the adoption of the LLC resonant circuit method has increased, and the high-precision resonant C0G characteristic has attracted attention. In addition to the expansion of the vehicle-related use, it is also effective for replacing various circuits and different types of capacitors with high reliability.
Term set· Resin electrode series: In the normal product, the terminal electrode layer is composed of three layers of copper (Cu), nickel (Ni), and tin (Sn). The resin electrode product is a terminal electrode of a four-layer structure in which a resin layer is interposed between a copper and a nickel layer.
· Overlapping products with metal terminals: A structure in which the terminal electrodes of the MLCC have metal terminals at both ends. There are 1 and 2 sections of laminate.
· C0G characteristics: Within the range of -55 to 125 °C, only the capacity change within 0.3%
The main purpose· Non-contact power supply unit such as electric and plug-in hybrid, LLC resonant circuit of car charger
· Various circuits requiring high reliability (time constant circuit, filter circuit, resonance circuit, oscillation circuit, buffer circuit), etc.
Main features and advantagesThe resin electrode series has extremely high reliability for preventing warpage cracks, thermal shock welding cracks and vibrations of the substrate due to the stress absorption effect of the terminal electrode layer. The laminated product with a metal terminal has a reliability exceeding the resin electrode product for preventing the substrate from warping cracks, thermal shock welding cracks and vibrations due to the stress absorbing effect of the metal terminals. In addition, the 2-segment laminate can achieve 2 times the electrostatic capacity.
