SRR1208-220ML is a shielded high-power inductor from Bourns' SRR1208 series designed for input/output filtering in DC/DC converters and power supply applications. The device features a 22 µH inductance at 1 kHz with a tolerance of ±20%, a quality factor (Q) of 23 at 2.52 MHz test frequency, and a maximum DC resistance of 0.043 O. It is rated for 3.5 A RMS maximum current with a saturation current of 4.0 A, operates with a self-resonant frequency of 7.0 MHz, and maintains a temperature rise of 40°C maximum at rated current. The inductor is constructed with a ferrite core, enameled copper wire, and LCP base with Cu/Ni/Sn terminals, housed in a compact form factor with a unit height of 8.5 mm and RoHS-compliant construction. It is commonly used in portable communication equipment, camcorders, LCD TVs, and other power conversion applications requiring reliable high-frequency filtering and energy storage.
