Current compensated chokes (DUS-9,8 type) wound on UU type core.

Current compensated chokes wound on UU core with split section bobbins. Current compensated chokes are used as a line filters, because of wide range of prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines. DUS type current compensated choke, even at its compact size, offers large inductance and keeps the high impedance levels required in high frequency ranges. Current compensated chokes are widely used in measuring equipment and system equipment.
