Additional Details:

The "PCMB053T" designates the series and package dimensions, while "3R3MS" indicates the inductance value (3.3µH) and tolerance. Saturation current and rated current are crucial parameters, and the Susumu datasheet will provide these values. Exceeding the saturation current can lead to a significant drop in inductance. The device is typically constructed with a ferrite core to provide high inductance in a small volume. Consult the official Susumu datasheet for complete specifications including dimensions, electrical characteristics, soldering recommendations, and temperature derating curves.
