Abstract
A PTC circuit protection device to protect electronic devices against excessive temperatures and electrical currents. The device comprises a polymeric resistor element, a first electrode, and a second electrode. The polymeric resistor element changes resistance in response to temperature changes. The resistor element has an upper surface and a lower surface. The first electrode is in electrical contact with both the upper surface and the lower surface. The second electrode is in electrical contact with both the upper surface and the lower surface. The circuit protection device has a first effective area of resistance and a second effective area of resistance that is electrically in parallel with the first effective area.
