Nippon Chemi-Con has developed the “FX Series”, a common mode choke coil that improves magnetic permeability at 100kHz by 145% compared to the previous model (FW Series). This product reduces size/weight and improves performance as a noise filter for switching power supplies, inverters, and automotive equipment.
Most electronic devices generate noise that need to be filtered and suppressed. As electronic equipment become increasingly dense on the circuit board, there is a need to reduce the size of noise filters so they can be installed in a limited space.
The FX Series has achieved a high permeability of 45,000µ (which is unique amongst nanocrystalline material cores) and high impedance characteristics in high frequency ranges. Both are very effective for downsizing and improving countermeasures for noise regulations. In other words, the FX Series can offer noise filters with the same performance but in a smaller size than conventional products.
Coil Dimensions [mm]：Outer Diameter 31×Width 18～ Outer Diameter 60×Width 39
Coil Specifications(Sample）：Rated Voltage 250V～1000V、Rated Current 5.5A～39A
Inductance(10kHz）3.5mH～38mH、(100kHz)1.0mH～11.5mH
Samples of the “FX Series” are already available, with mass production scheduled for June 2025 onwards. Production will take place at Chemi-Con East Japan Corp. Iwate Plant (a wholly owned subsidiary of Nippon Chemi-Con).
