Common-mode Coils
Common-mode coil is a small-type, high-performance differential mode choke coil for line noise filter. These coils are endowed with unique characteristics and ensure excellent performance, compared with the conventional differential mode choke coils employing ferrite cores. 1. FEATURES: 1)  Has high inductance, compared with the conventional fifferential mode choke coil to the same size over five times higher at 10KHz and approximately twice higher at 100KHz. 2)  Highly effective in reducing impulse noise due to a hihg maximumn flux density of 0.9T. 3)  Has High impedance in a wider frequency band , due to a smaller Q-value compared with that of differential mode choke coils imploying ferrite cores. 4)  Due to a high Curie temperatrue of 570℃, the Common-mode coil manifests stable magnetic characteristics at a higher temperatrue range, compared with the differential mode choke coils employing Co-based amorphous cores, and its inductance does not drop as dramatically as that of differential mode chokd coils employing ferrite cores at a lower temperature range. 2.APPLICATIONS: Computers, peripheral terminals, copiers, telecommunications equipment ,UPS, inverters, NC machines, automatic vending machines, car electronics, high-vision TVs, projection TVs, broadcasting equipment, medical equipment ,etc. 3.STANDARD SPECIFICATIONS: NO.
