SRR1210-331M is a shielded SMD power inductor from the SRR1210 series designed for DC/DC converter input/output filtering and power supply applications. The device features an inductance of 330 µH at 1 kHz with ±20% tolerance, a self-resonant frequency of 1.8 MHz, and a maximum DC resistance of 1.4 mO. It is rated for 1.2 A RMS continuous current with a saturation current of 4 A, operates over a temperature range of -40°C to +125°C, and exhibits a typical temperature rise of 40°C at rated current. The inductor is constructed with a ferrite core (DR & RI materials) and enameled copper wire with matte tin terminal coating, making it ideal for portable communication equipment, camcorders, LCD TVs, and other compact power management applications requiring high current density and low profile performance.
