PTC THERMISTOR
FOR DEGAUSSING
PTH451/632 Series
The PTH451/632 are degaussing elements used to
automatically degauss color TV’s and color monitors
on startup.
FEATURES
s
No noise is emitted.
s
Long life characteristic since part does not have
relay contacts.
s
Winding of degaussing coil can be reduced since rush
current is large.
s
Degauss operation can be performed in a simple circuit.
s
Degauss operation can be performed shortly after
shutdown due to a quick return to normal resistance.
