3.9uH, 0.555A color ring inductor | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics
3.9uH, 0.555A color ring inductor with dimension 3.0x7.0mm. Utilize the high performance ferrite core and treated epoxy resin coating to achieve the high Q factor and SRF (self-resonant frequencies). The epoxy resin coating not only provide the better protection for high inductance value of this axial leaded power inductor, better resistance to humidity resistance and ensure long life. The epoxy conformal coated power inductor featur with wide range of inductance value and light weight. Coilmaster Electronics is a high-current 3.9uH, 0.555A color ring inductor, 3.9uH, 0.555A axial leaded color coated inductor manufacturer from Taiwan since 1995. Coilmaster is a professional manufacturer for inductor, common mode choke, chip beads and transformer. Our vision is “Creating high-performance inductors, reducing energy loss, and contributing to sustainable” To achieve this, our engineer team is keen to design the power inductor to have better efficiency. With more than 20 years of experience in magnetic territory, Coilmaster Electronics is specialized in the production of SMD power inductors, common mode choke, high frequency transformers.
