Additional Details

The FCI3216-4R7K has an inductance value of 4.7 µH with a tolerance typically around 10%. Its Self-Resonant Frequency (SRF) will vary depending on the specific design but it is an important parameter for high-frequency applications. The component's DC Resistance (DCR) is a key characteristic to consider for power efficiency; lower DCR generally translates to lower losses. It is crucial to consult the manufacturer's datasheet for the most accurate and detailed specifications, including the saturation current rating. This rating indicates the maximum current the inductor can handle before its inductance value significantly drops. The component's reliability is determined by factors such as its operating temperature range and its ability to withstand mechanical stress during assembly and operation.
