Additional Details:

The SLF6020T series utilizes a ferrite core material, which contributes to its high inductance and low core loss. The inductance value for the SLF6020T-680MR40-PF is 68µH (680M), with a tolerance to allow for slight variations. The rated current is approximately 0.40A (R40), representing the maximum current the inductor can handle without significant performance degradation. The component's dimensions are approximately 6.0mm x 6.0mm x 2.0mm. This inductor is designed for reflow soldering processes common in SMT assembly. Its operating temperature range is typically between -40°C and +125°C, making it suitable for a variety of environmental conditions. The self-resonant frequency (SRF) is an important parameter indicating the frequency at which the inductor's behavior transitions from inductive to capacitive; above this frequency, the inductor is no longer effective.
