Film Capacitors for xEV
We independently develop and manufacture “DC Link Capacitors”, “Filter Capacitors”, “Snubber Capacitors” and “Noise Filter Capacitors” for xEV motor drive inverters from the basic raw material of metalized film. In particular, our film capacitor modules used in power inverter modules have excellent high-frequency characteristics and current-performance resistance, and they are long lasting, highly reliable, and very safe. In addition, they can be flexibly coinfigured to match the required shapes, and hence they are highly rated by domestic and overseas automotive companies. We are currently working on strengthening our supply system in order to meet the increasing demand of these products.

<Test conditions>
Ambient temperature: room temperature Voltage application time: 1 minute for each step
* In this test, the test power supply is shut off by detecting the short mode with the overcurrent, but there is a possibility of burning or fire if it is not shut off.

Product development by simulation
We use our own database, created based on past results, to carry out simulations such as thermal analysis, inductance analysis, and vibration analysis. With this, we increase the speed of development and reduce the number of prototypes.
