The SPM3015-330M with 520mA 33uH ±20% 1.26A SMD,3x3x1.5mm Power Inductors ROHS from KOHER is an electronic component primarily used for inductance. It is a formally approved type of inductor that has a DC resistance rating of 0.18 ohms. This inductor has low DC resistance for low loss applications. It also has a wide range of high current rating up to 1.26 amps and allows for a high saturation current up to 1.46A. The inductor is also a surface-mount device (SMD) with dimensions of 3x3x1.5 mm and is compliant with RoHS-certified standards. The inductance tolerance is ±20%, with a rated inductance of 33 µH (at 520 mA DC). Finally, this inductor is an excellent choice for use in power line filtering applications, like power supplies, chargers, adapters, and the like.
