RCT models have a metal alloy, wire wound, ceramic core element connected to a
thermal fuse.  This system is housed in a thermally conductive ceramic case and
then sealed and insulated with inorganic filler.  These models exhibit excellent surge
handling capability, high stability and quick response to overload and temperature
conditions.  Applications include:  PDP power supplies and circuits preventing current
inrush to switching regulators.
