Additional Details:

The "PCMB061H" designation refers to the series and physical dimensions of the inductor. "3R3MS" indicates the inductance value (3.3 µH) and the tolerance. The molded construction offers excellent resistance to moisture and physical damage. The saturation current and rated current are critical parameters specified in the Susumu datasheet; operating the inductor above these limits can lead to performance degradation. The inductor is designed for surface mount assembly, which simplifies manufacturing. For detailed specifications, including dimensions, electrical characteristics, soldering guidelines, and temperature derating curves, refer to the official Susumu datasheet.
