Additional Details:

The SCDS105R-820M-N features an inductance value of 82μH with a tolerance of ±20%. The high saturation current, typically around 1.1A, enables the inductor to handle significant current loads without a drastic reduction in inductance. The low DC resistance minimizes power losses due to the inductor's internal resistance. The shielded construction is vital for reducing EMI and ensuring stable performance in sensitive electronic circuits.

The 'R' in the part number indicates RoHS compliance, and the 'N' signifies suitability for lead-free soldering processes. The self-resonant frequency (SRF) is approximately 3.5 MHz. This inductor is intended for surface mount assembly and is compatible with standard reflow soldering profiles.
