Additional Details:

The SLF6028T series incorporates a ferrite core material, which is instrumental in achieving high inductance and low core loss. The inductance value for the SLF6028T-100M1R3-PF is 10µH (100M), with a tolerance to accommodate minor variations. The rated current is approximately 1.3A (1R3), indicating the maximum current that the inductor can handle without significant performance degradation. The dimensions of the component are approximately 6.0mm x 6.0mm x 2.8mm. This inductor is designed to be used with reflow soldering processes, which are standard in SMT assembly. The typical operating temperature range spans from -40°C to +125°C, making it suitable for a wide range of environmental conditions. The self-resonant frequency (SRF) is a crucial parameter, representing the frequency at which the inductor's behavior transitions from inductive to capacitive, effectively limiting its usefulness beyond this point.
