Small Radial inductor DR6*8 1.5mH±5% 235 turns inductance value up to 500mH Leaded inductor with ferrite core
DR radial inductor
The DR inductor is a small electric component which occupies a small area on PCB. The four models of our DR inductor mainly differ in appearance. The two pins of the PK model are on the same side, while the VC model put the pins on separated sides. Different models may have different overall sizes, pin lengths, pin diameters, or pin intervals. Our production process is very precise so that the difference in pin length is less than 2mm, and the difference in pin intervals is less than 0.3mm.
