Additional Details

The SCDR104-150M features an inductance value of 15 μH (microhenries), as indicated by the '150' marking, where '150' typically signifies 15 x 10^0 μH. The 'M' at the end usually denotes the inductance tolerance (e.g., ±20%). Consult the Yageo datasheet for the precise tolerance value and other specific parameters.

Key technical specifications include the saturation current (Isat), which represents the current level at which the inductance value drops by a certain percentage (e.g., 10% or 20%), and the rated current (Irms), indicating the maximum continuous current the inductor can handle without exceeding a defined temperature rise. The operating temperature range and DC resistance are also crucial parameters found in the product datasheet.

The inductor's shielded construction involves a ferrite core that confines the magnetic field and minimizes EMI. The specific core material and winding configuration influence its performance characteristics, such as the Q-factor (a measure of efficiency) and the self-resonant frequency (SRF).

The SCDR104-150M from Yageo is a high-performance, shielded power inductor designed for a wide range of power management applications. Its compact size, shielded design, and high current handling capabilities make it a preferred component for modern electronic devices requiring efficient and reliable power conversion and filtering.
