Signal Transformer / Bel SFAPI Fixed Axial Power Inductors

Signal Transformer / Bel SFAPI Fixed Axial Power Inductors feature high permeability, impressive electrical resistivity, and low eddy current losses. These power inductors oppose any changes in current that pass through the coil. The SFAPI power inductors can be coupled with a capacitor to prevent sudden changes in the output voltage and current of power supplies. These fixed axial power inductors feature high current choke, wide inductance range, and high saturation ferrite core. The SFAPI power inductors operates with the -40°C to 125°C temperature range. Typical applications include switching regulators, power supplies, speaker crossover networks, and RFI suppression filters.
