A modern range of surface mount high

current power chokes, suited to a

range of industrial applications. Low

cost, twelve convenient sizes and large

area terminals providing excellent

solder flow connections, are key

design advantages of the 3621 series.

Current ratings up to 20 Amps (Isat)

can be achieved.
