Bel F1A1 Shielded SMT Power Inductors

Bel F1A1 Shielded SMT Power Inductors are available in a small footprint with a wide range of inductance and current ratings, making them ideal for a variety of applications. The inductors feature an overall height profile of 1.2mm to 1.8mm and three footprint options: 3mm x 3mm, 3.8mm x 3.8mm, and 4.6mm x 4.6mm. These magnetically shielded inductors minimize electromagnetic interference (EMI) while balancing a small size with high current ratings and low DC resistance (DCR). Bel F1A1 Shielded SMT Power Inductors are RoHS and REACH compliant and operate in a -40°C to +105°C temperature range (including coil self-temperature rise). The F1A1 devices are ideal as power chokes and for eliminating noise in power supplies in automotive, industrial, commercial, and high-reliability applications.
