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.

Notes
1. All peak-to-peak currents are measured at typical resistance of the coil, at 50 Hz (AC), at 25ºC and at 220 Vrms for the 276V types, and 110Vrms for the 145V types.
2. The indicated resistance value is the parallel combination of two degaussing PTCs.
3. Decay time is the time from the moment of maximum peak current until the half of the maximum peak inrush current.
4. Alpha maximum is the maximum decrease in current expressed in percent between two successive peaks.
5. Inrush currents and decay times at other voltage coil combinations can be derived from Figures 8 to 14 in the section,
“Introduction, PTC thermistors for degaussing”.
6. LT = low tolerance; LD = long decay.
