Network Interferference Suppression
The proven asymmetrical interference suppression components from SUMIDA AG are mainly found in the interference suppression of switch mode power supplies. For damping common mode interference, so-called “current compensating chokes” are required – these inductivities are primarily based on higher permeable cores with two identical windings. SUMIDA AG ensures that for relatively small sizes in designs, windings with a smaller self-capacitance are used, which results in higher resonance frequencies. Due to the fact that symmetrical interference can also occur in circuits, the SUMIDA AG portfolio encompasses – alongside the classical interference suppression components – self-designed interference suppression chokes in the RK17S, RK23S and DPF14S series.
