3.9uH, 4.5A SMT unshielded power inductor | Magnetic components | Transformer, Inductor, Choke Manufacturer | Coilmaster Electronics
3.9uH, 4.5A SMT unshielded power inductor with dimension 10.0x10.0x4.6mm. SDB series were designed for different applications features low DC resistance and increased allowable current. Especially in DC-DC converters and power supplies, the performance of the power components directly affects the overall efficiency of the supply ,so it is of paramount importance. Due to the magnetically unshielded construction and special winding design, the product have higher saturate current and excellent self resonant frequency value. Coilmaster Electronics is a high-current 3.9uH, 4.5A SMT unshielded power inductor, 3.9uH, 4.5A SMD high self resonant frequency 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.
