Signal Transformer is introducing the beginning of a new family of low-profile shielded surface mount power inductors with the release of the second of three series, F1A2-3838. Height profiles of 1.2 mm to 1.8 mm, small footprints of 3.8 mm x 3.8 mm and broad range of inductance and current ratings, make them idea 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. Perfect as power chokes eliminating noise in power supplies for automotive, commercial, industrial, and high-reliability designs. They are primarily used in electrical power and electronic devices for these major purposes: Choking, blocking, attenuating, or filtering high frequency noise in electrical circuits. Storing energy in power converters (DC-DC or AC-DC) or inverters (DC-AC).
