PM105-121K-RC is an SMD power inductor from the PM105 series featuring a 120 µH inductance at 1 kHz with ±10% tolerance. This compact component measures 9.8 mm maximum diameter and is RoHS compliant, making it suitable for modern electronic applications. The inductor exhibits a DC resistance of 0.40 O, a maximum RMS current rating of 0.89 A, and a typical saturation current of 1.50 A, with a self-resonant frequency of 5.0 MHz. It is commonly used in input/output filtering of DC/DC converters and power supplies for portable communication equipment, camcorders, and LCD TVs, where its small form factor and reliable performance provide significant advantages in space-constrained designs.
