APPLICATIONS
• Colour televisions
• Colour monitors.
DESCRIPTION
For good picture definition, colour televisions and monitors
must be degaussed by a strong alternating magnetic field
which gradually and symmetrically decays to a small value of
residual current. This can be achieved by connecting a PTC
thermistor in the degaussing circuit.
The new generation of flat-screen, high-definition colour
televisions and monitors require an excellent picture quality
with high colour purity. This can only be achieved by a dual
PTC device housing two PTC thermistors in intimate thermal
contact, one being used to heat the other and so further
reduce the residual current.
