KN- Series

KN Series: Vertical and Horizontal Mount Nanocrystalline Common Mode Choke and Amorphous Common Mode Choke
- Current Rating of 13 Amps to 40 Amps, Inductance from 4.6mH to 48 mH and DCR from 1.3 milli-ohms to 17 milli-ohms.
- Suitable for high and low ambient temperatures. Operating Temperature of 200 deg C.
- UL 94VO compliant and meets 3mm creepage spacing for UL, CSA, TUV and IEC specifications
- Exhibit excellent frequency response from 50 Hz to 10 Mhz

APPLICATION: Switch Mode Power Supplies, Power Line Filtering, Filters contact noise, Solar Inverters, Frequency Converters, EMC filters, Welding equipments, Wind generators, Automotive applications, Uninterruptible Power Supplies, Inductive heating, etc.

USEFUL TIPS: The SRF is where the peak impedance or the peak insertion loss occurs. Engineer should select the parts where the SRF coincides with the frequencies that have the highest noise amplitudes.
