Additional Details:

The SLF6020T series incorporates a ferrite core material, which enhances its high inductance and minimizes core loss. The inductance of the SLF6020T-220MR67-PF is 22µH (220M), with a tolerance range to allow for minor deviations. The rated current is approximately 0.67A (R67), signifying the highest current that the inductor can handle without significant degradation in performance. Its dimensions are roughly 6.0mm x 6.0mm x 2.0mm. This inductor is designed for use with reflow soldering techniques, which are standard in SMT assembly. The typical operating temperature spans from -40°C to +125°C, accommodating a broad range of operational environments. The self-resonant frequency (SRF) is a crucial metric, indicating the frequency at which the inductor's behavior shifts from inductive to capacitive, effectively limiting its usefulness beyond this point.
