Magnetically compensated chokes, used for RFI suppres-

sion in equipment with relatively high asymmetric interfe-

rence. Due to its current compensation characteristic, this

type of choke presents an active broad-band series impe-

dance.

This range of chokes enables vertical mounting, thus reducing the area of

PC board used. Finest quality core materials allow the highest electrical

performance with minimum component volume. Good design with easy

assembly allows good cost/performance ratio.

powersupplies, chopperamplifiers, DCdrivesandsteppermotorcontrols.

Environmental ratings:

Magnetically compensated chokes can only be

used when current is compensated. The cur-

rent flowing into the choke on one (•) -side

must flow 100% out of the choke from the

other (•) side (see examples). Under different

conditions the choke will be saturated by the

lowest currents and the attenuation efficiency

is lost.
