3.9uH, 5.7A Low profile SMD choke coils
SDR0705K-3R9M-LF
3.9uH, 5.7A Surface mount wirewound miniature inductors
3.9uH, 5.7A Low profile SMD choke coils, design wiht compact size 7.8x2.6x5.3mm. Various high power inductors are superior to be high saturation for surface mounting and offer various dimension. Mainly used by power supply for VRT,OA equipment Digital camera, LCD television set notebook PC, portable communication equipment, DC/DC converters, etc.This miniature wirewound SMD power inductor produce by fully automated winding / soldering / testing and packing machine. 100% check before each shipment, the testing included the characteristic inductance value, DC resistance, Isat current and layer isolation. This offer customer reliable quality and stable (short) delivery date (urgent case, the delivery date could be 2~3 weeks only). This silver plated SMD wirewound power inductor is suitable for low cost design and the adjacent component is not affected by the magnetic flux outside core influence. Compare to the same dimension shielded or semi-shielded product, the unshielded SMD power inductor could carry high saturate and rated current.
Customization
Due to the solid background of our engineer team at ferrite powder territory, we could modify the core powder, design and produce the most suitable product to fit customer's applications. Except for the standard characteristic of our series specification, Coilmaster Electronics also offer the customization product with low minimum order quantity (MOQ), tighter tolerance, different inductance and frequency 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.
