PTC THERMISTOR
FOR DEGAUSSING
www.DataSheet4U.com
PTH451/632 Series
The PTH451/632 are degaussing elements used to
automatically degauss color TV’s and color monitors
on startup.
FEATURES
I No noise is emitted.
I Long life characteristic since part does not have
relay contacts.
I Winding of degaussing coil can be reduced since rush
current is large.
I Degauss operation can be performed in a simple circuit.
I Degauss operation can be performed shortly after
shutdown due to a quick return to normal resistance.
