PPTC device having resistive component
A PPTC assembly may include a PPTC component, having a trip temperature, and further comprising a first temperature coefficient of resistance, in a low temperature range below the trip temperature. The PPTC assembly may include a resistive component, disposed in electrical contact with the PPTC component on a first side of the PPTC component, the resistive component comprising an electrical conductor, and having a second temperature coefficient of resistance in the low temperature range, less than the first temperature coefficient of resistance. The PPTC component may include a first electrode, electrically coupled to the first side of the PPTC component, and a second electrode, electrically coupled to the second side of the PPTC component, where the PPTC component and the resistive component are arranged in electrical series between the first electrode and the second electrode.
