The MBFS7045 Series is a robust, magnetically shielded SMD Shielded Power Inductor in a 7.0 mm × 7.0 mm footprint with a 4.5mm profile. This model is engineered for higher power efficiency and superior EMI suppression across a broad inductance spectrum.
This series is distinguished by its exceptionally wide inductance range, offering values from 1.0µH all the way up to 1000µH. Its closed magnetic circuit design reduces leakage flux, providing a higher current capability inductor than conventional types. The MBFS7045 is a highly versatile, space-saving smd high current power inductor solution for demanding automotive, server, and notebook power supplies.

Notes:
Test Conditions: All test data is referenced to 25°C ambient.
Operating Temperature Range: -40°C to +125°C (ambient plus self-temperature rise).
Idc (Heating Current): DC current (A) that will cause an approximate ΔT of 30°C.
Isat (Saturation Current): Based on $\Delta L / L_0 = 10\%$ typ. (for 1R0M~221M); Base on $\Delta L / L_0 = 25\%$ typ. (for 271M~102M).
Temperature Limit: The part temperature (ambient + temp rise) should not exceed 125°C under worst-case operating conditions.
