3.3uH, 21.5A SMD Shielded Dual Winding Power Inductors

This dual winding inductor is a cost-effective and small solution of dual inductors with two windings (8mm height), with 3.3uH and 21.5A of saturate current. With magnetically shielded construction provide low emi emission and leakage flux. Due to our advanced winding technology, this dual winding shielded common mode choke have excellent coupling factor and low stray inductance. The two windings can be connected in series or parallel, it offering a board range of inductance value and current ratings. That means it could categorized to inductor mode (boost and coupled inductor) / transformer mode(flyback transformer or SEPIC). Coilmaster is fully understand that the stable quality is the most important point, hence most of the production process for this series is semi / full automated. All of the product will test characteristic 100%.

Customization

Except for the standard characteristic of our series specification, Coilmaster Electronics also offer the customization product with low minimum order quantity (MOQ). Because our engineer team has a solid background at ferrite powder territory, we could modify the core powder, design and produce the most suitable product to fit customer's applications.

Leadtime

Coilmaster’s standard lead time is 6~8 weeks, in urgent case, the fast delivery program is available. For specific product series, we could send out the goods within 10 or 20 working days.
