Sumida has developed a series of surface-mounted power inductors for resin-filled coils. The product size range is wide. This series includes CD3015MB/DS(3.2*3.2*1.5mm Max.), CD4012MB/DS(4.2*4.2*1.2mm Max.), CD4018MB/DS(4.2*4.2*1.8mm Max.), CD4030MB/DS(4.2*4.2*3.0mm Max.), CD5020MB/DS(5.2*5.2*2.0mm Max.), CD5040MB/DS(5.2*5.2*4.0mm Max.), CD6020MB/DS(6.2*6.2*2.0mm Max.) and CD6028MB/DS(6.2*6.2*2.8mm Max.).

By filling the winding wire with resin containing magnetic material, the magnetic shield effect and the mechanical impact strength is significant.
