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.
