I04-4R7-3R3-

The I04 series has been designed in collaboration with On Semiconductor to work with the NCP1207 controller as a  econd stage output filter. With multiple inductance values at popular output current levels, the I04 series provides  olutions for a range of output filtering needs. The low DCR values minimize the voltage drop across the inductor and  inimize losses due to temperature rise. The low cost designs utilize powdered iron cores from Micrometals to  liminate the risk of long term instability.

The NCP1207 is a PWM current-mode controller for free running quasi-resonant operation. Applications include  otebook and offline battery chargers, consumer electronics, set-top boxes, medical power supplies, etc.
