Three Step Inductor

Arco three step inductor is a heavy duty fixed inductor, which is available via. 4 mm safety termils. In this inductor, copper emeled wire is wound over an insulated spool and covered with two plastic side covers. The side covers of the inductor are made of Acrylo Nitrile Butadiene Styrene (ABS) material. The front plates are made of milky white acrylic sheet. There is facility in the side cover to easily carry it. One can easily change the inductor value of the instrument on just inserting a soft iron core of diameter 30 mm inside the bobbin. The coil consists of 4 layers of 200 turns each. This produces 4 coils with coils numbering. The output inductors are available in the following pattern. No. of turns Inductor Resistance 200 0.3mH 0.6? 400 1.2mH 1.2 ? 800 5mH 2.6 ?
