WebbA PTC thermistor is a thermally sensitive resistor for which the resistance increases significantly with increasing temperature. Characteristics of PTC Thermistors. Silistors … WebbTo better understand how thermal resistance is used, lets look at the following example: Power dissipated: 2W. RθJC = 4°C/W. RθCH = 0.25°C/W. RθHA = 6°C/W. TA = 25°C. Starting with the thermal equivalent of Ohm's Law: We want to solve for our junction temperature rise , so T becomes T J. Our power dissipated, P, is 2W.

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance. • (Absolute) thermal resistance R in kelvins per watt (K/W) is a property of a particular component. For example, a characteristic of a heat sink. WebbWhat are RTD temperature sensors? RTDs - or Resistance Temperature Detectors - are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The most popular RTD is the Pt100.
