PM105SB-221K-RC is a shielded surface-mount power inductor from the PM1065B series designed for input/output filtering in DC/DC converters and power supplies. It features an inductance of 220 µH at 100 kHz with ±10% tolerance, a maximum DC resistance of 0.78 O, and a rated DC current of 0.47 A. The inductor has a self-resonant frequency of 5 MHz, a quality factor of 27 at the test frequency of 0.796 MHz, and operates reliably over a temperature range of -40°C to +125°C. With a compact height of 2.9 mm and ferrite core construction, it is ideal for portable communication equipment, camcorders, LCD TVs, and other compact power management applications requiring efficient energy storage and filtering.
