TDK Product Features
A typical application for switching PTCs is the preheating of electrodes in energy-saving lamps of fluorescent lamps. A full range of standard devices is available and custom-engineered samples can be rapidly created. Switching PTCs can also be used as a power resistor for loading capacitors for example in power supplies or in control units of production equipment. Housed PTCs are recommended in case of a large number of switching cycles.
