The resistance of a AOLITTEL PPTC device under specified conditions (eg: at 20°C), before connection into a circuit. Devices of a particular type will be delivered with a range of resistances; therefore, a minimum value (Rmin), and/or a maximum value (Rmax) are often given. The maximum resistance of a AOLITTEL PPTC device at room temperature one hour after being tripped or after reflow soldering is R1max.
