Additional Details

The MSRH5D18-100MT inductor typically features a ferrite core. The inductance value is nominally 10µH, but this should be confirmed on the datasheet for this specific part number. Key specifications include the saturation current (Isat), which indicates the current level at which the inductance begins to drop significantly, and the rated current (Irms), which indicates the maximum continuous current the inductor can handle without exceeding its temperature limit. The DC resistance (DCR) is typically very low, in the milliohm range. The shielded construction helps to minimize electromagnetic interference, which is crucial in sensitive electronic circuits. When selecting an inductor for a specific application, it is essential to consider the operating frequency, current requirements, and desired inductance value. This series is often used where a low profile and high current handling are needed. Make sure to check the manufacturer's datasheet for complete specifications before use.
