Signal Transformer is introducing the beginning of a new family of low-profile unshielded surface mount power inductors with the release of the first of three series, F1B1-303010/303012/303015. Height profiles of 1.0 mm to 1.5 mm, small footprints of 3.0 mm x 3.0 mm and broad range of inductance and current ratings, make 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. Compared to the shielded construction (in the same dimension, inductance value), the unshielded power inductor has a higher current carry capacity (higher saturation current rating) and suitable for price-sensitive or uncritical applications for low power circuits, general purpose power choke or power supply applications. Unshielded power inductors are used in electrical power and electronic devices for these major purposes: Choking, blocking, attenuating, or filtering/smoothing high frequency noise in electrical circuits. Storing and transferring energy in power converters (DC-DC or AC-DC).
