Signal Transformer

Shielded SMD Power Inductors – F1A1 Series

Signal Transformer's inductors help to store energy, reduce signal losses, and filter EMI noise and ripple currents

Image of Signal Transformer's Shielded SMT Power Inductors - F1A1 SeriesSignal Transformer’s low-profile, shielded, surface-mount power inductors feature height profiles of 1.2 mm to 1.8 mm and a broad range of inductance and current ratings, making them ideal for a wide range of applications. Power inductors are an essential component in the voltage regulator topology. Virtually every circuit that regulates power in automobiles, electronics, and DC/DC converters requires an inductor. Magnetically shielded inductors minimize EMI while balancing small size with low DCR and high current ratings. They are perfect as power chokes and for eliminating noise in power supplies in automotive, commercial, industrial, and high-reliability designs.
