PTC thermistors, general technical information

5.1.2 Rated resistance RR The rated resistance RR is the resistance value at temperature TR.PTC thermistors are classified according to this resistance value. The temperature TR is 25 °C, unless otherwise specified. 5.1.3 Minimum resistance Rmin The beginning of the temperature range with a positive temperature coefficient is specified by the

variety of dielectrics, each with different behavior over temper - ature and applied voltage. Capacitors must have a dielectric adequate to ensure that the minimum capacitance is provided over the working temperature range and dc bias conditions. X5R or X7R dielectrics with a voltage rating of 6.3 V or 10 V are recommended for 5 V applications.
