ductance. One of the chokes has a two-layer winding and the other is randomly wound. The choke
with random windings has a considerably higher first resonance frequency. The spurious resonanc-
es are very much higher than 10 MHz. The impedance at frequencies above the first resonance fre-
quency is approximately five times higher. This leads to better interference suppression at high
frequencies.

The RF characteristics of all chokes supplied by EPCOS are within the specifications and reproduc-
ible, as the winding processes which we have developed for single-layer, multilayer and random
winding ensure that the characteristics of the inductors produced display very little variation.
The reproducibility of electrical characteristics of chokes is mainly determined by the production
technique used. At EPCOS, coils are wound mainly by automatic machines (either fully or semi-au-
tomated). This permits even complicated winding patterns to be produced in large production runs
with very little variation in product characteristics. In
chokes, some wound manually and some by machine, are shown for comparison. With the random
winding used in this comparison, the advantages of machine winding are clearly noticeable.
