820uH, 0.35A High Current Shielded Coupled Inductor
SDS74BQ-821M-LF
820uH, 0.35A Dual winding shielded common mode choke
Dual winding inductors(1:1 turns ratio) that can be used as either a single inductor, or in coupled inductor / transformer applications. This shielded dual winding inductor utilize the ferrite drum core features with space saving (7.5x7.5x4.45mm) with 820uH and high saturate current 0.35A, cost effective and high k factor. The two windings can be connected in series or parallel, offering a broad range of inductance and current ratings. This shielded common mode choke inductor also could design for different turn ratio to meet various requirement, the function is like the transformer. Furthermore, the isolation between windings could up to 200 Vac and have excellent operating temperature up to +125 °C.
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.
