F1B1 Unshielded Power Inductors

Signal Transformer / Bel F1B1 Unshielded Power Inductors feature a low profile, -40°C to +105°C operating temperature range, and a maximum inductance rating of 56µH. These inductors come in nine series with dimensions ranging from 3.0mm x 3.0mm to 4.6mm x 4.6mm. Unshielded power inductors offer a higher current carry capacity compared to shielded construction, and they are suitable for uncritical use in low-power circuits, general-purpose power chokes, and power supply applications. Additional features include a surface-mount design, copper base with DR core, and a wide saturation current range. Signal Transformer / Bel F1B1 Inductors are ideal for mobile phones, digital equipment, EMI noise filters, and various power supply environments.
