DM Dust Choke Coils

Chemi-Con DM Dust Choke Coils offer a 3A to 10A maximum DC current range, 760µH maximum inductance, and a DC resistance of 25mΩ to 72mΩ. These coils exhibit excellent DC superimposition characteristics and achieve significant miniaturization. DM coils feature a great reduction of core loss, enabling low temperature rise at high frequencies. Chemi-Con DM Dust Choke Coils are ideal for power factor correction (PFC) use in switching-mode power supplies.
