Additional Details:

The SLF6028T series utilizes a ferrite core material, contributing to both high inductance and low core loss characteristics. The inductance value for the SLF6028T-1R0M2R7-PF is 1.0µH (1R0M), with a tolerance to accommodate slight variations. The rated current is approximately 2.7A (2R7), representing the maximum current 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 for reflow soldering, a common technique in SMT assembly. The typical operating temperature range is from -40°C to +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's performance is diminished.
