Introduction
With its new range of surface-mount coil formers, Philips
Components offers a real solution to circuit designers
wishing to take maximum advantage of surface-mount
technology in their designs.
The trend toward full surface-mount technology has been
hampered by the problems of introducing inductive
components (inductors and transformers for example) in
surface-mount execution.
These devices, consisting of cores, coil-formers and
windings held together by clips, were not easily converted
to surface-mount versions, and former designs, based on
"gull-wing" terminations (see Fig.1) have not been entirely
satisfactory.
Disadvantages of "gull-wing" pins
In particular, tensions introduced by the winding wire,
which is wrapped around the upper part of the gull-wing
terminations, can severely degrade the coplanarity of the
solder pads. The use of thin wire windings is a partial
solution to this problem but this introduces limitations on
coil design. Furthermore, during soldering of the winding
wire to the termination, spillage of solder onto the solder
pad can further degrade coplanarity. However, for very
small coil formers gull-wing pins are the only possible
design due to space limitations. For small to medium sized
coil formers there is a better solution: U-pins.
