Recommended Inductors Manufacturer Part Number Mitsumi C13-FR Series, Type # GA 102 API Delevan 4590-105K J.W. Miller 5900-102 2. Specifications for Inductor We recommend an inductor with these specifications: an inductance of 1mH, rated current of at least 500mA, and good performance with DC superimposition. Please note there must be no magnetic saturation in the inductor. The following waveforms illustrate good versus bad inductor for this application. They are output ripple voltage waves taken with the oscilloscope on AC coupling. GOOD INDUCTOR 50.0mV/div 4 50.0µsec/div BAD INDUCTOR 50.0mV/div 50.0µsec/div
