The stray inductance L
both coils when a current-compensated choke is short-circuited at one end. This affects symmetri-
cal interference.

The inductance decrease L / L
inductance L
crease is caused by the magnetization of the core material, which is a function of the field strength,
as induced by the operating current. Generally the decrease is less than 10 % .
7.10
The dc resistance is the resistance of a line as measured using direct current at a temperature of
20 C, whereby the measuring current must be kept well below the rated current.

Parasitic capacitances ( C
the component geometry. These capacitances may affect the two lines mutually (symmetrically) as
well as the line-to-ground circuit (asymmetrically). The design of all EMC components supplied by
EPCOS minimizes the parasitic effects. Due to this, these components have excellent interference
suppression characteristics right up to high frequencies.

The quality factor Q is the quotient of the imaginary component of the impedance divided by the real
component.
