Technical Specifications: The D03316P-223 typically features an inductance value of 22µH. It has a saturation current rating which specifies the maximum DC current the inductor can handle before its inductance drops significantly (typically around 10-20% drop). The DC resistance (DCR) is very low, usually in the milliohm range, minimizing power losses. The operating temperature range is wide, typically from -40°C to +125°C, making it suitable for harsh environments. The specific dimensions can be found in the Coilcraft datasheet, but it's generally a small, surface-mount component.

In summary, the Coilcraft D03316P-223 is a reliable and efficient shielded power inductor ideal for a wide range of power supply and filtering applications. Its high current handling, low DCR, and compact size make it a suitable choice for modern electronic designs where efficiency, compactness, and EMI performance are crucial.
