a. Dual or double mono PTC degaussing.

APPLICATIONS

handbook, halfpage

• 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.

CCB442

b. Mono PTC degaussing.

Fig.1 Component outlines.

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.
