Additional Details

The D01608C-222MLC inductor features an inductance value of 2.2µH (2.2 microhenries). The “MLC” suffix may relate to a specific tolerance range, packaging or termination style. The component typically consists of a ferrite core, wound with high-quality copper wire, and fully shielded. Critical parameters to consider when selecting this inductor include the saturation current, DCR, self-resonant frequency (SRF), and operating temperature range, all of which are detailed in the manufacturer's datasheet. Proper thermal management is crucial to ensure reliable operation, especially at high currents. Automated pick-and-place compatibility simplifies the manufacturing process. Engineers should carefully consult the datasheet to ensure proper application and avoid exceeding maximum ratings, which could lead to component failure or performance degradation.
