Capable of handling up to 3A, SPR Series of power chokes offers inductance values of 1 to 10,000 µH and are auto-insertable. Current ratings are 50 mA to 3A with current handling and inductance in inverse relationship. DCR maximums are 0.007 ohms for 3A SPR-1ROK to 26.5 ohms for the 50 mA SPR-103K. The chokes are flow and reflow solderable, and all cores are composed of ferrite material-the cores are bonded to carriers. Operating temperature range is -45°C to 125°C.
