the change in measured value per unit change in temperature. The higher the temperature coefficient the more sensitive the device is to temperature changes.
The ratio of the speeds of a chemical reaction at two temperatures differing by 10°C. It varies with different materials but is generally near 2 (i.e., the reaction rate doubles for each rise of temperature by 10°C), especially for reactions involving water vapor. This value may be connected with the fact that equilibrium vapor pressure nearly (but not quite) doubles for a rise of temperature by 10°C. The temperature coefficient for bacterial action is also near 2.
The effect of ambient temperature changes upon output voltage regulation, expressed as a percentage change per degree of temperature.
The average output voltage change expressed as a percent per degree centigrade of ambient temperature change. This is usually specified for a pre-determined temperature range.
The amount of change of resistance in a material per unit change in temperature.
The average percent change in output voltage per degree Centigrade change in ambient temperature over a specified temperature range.
The amount of drift, in percent of full scale output, that might result from a 1°C change in ambient temperature.
The temperature coefficient is determined by the average percent of change in output voltage per temperature degree change while the input voltage and load levels remain the same.
The rate at which a parameter varies versus change in temperature.
The change of value or function corresponding with a change in temperature. This is often expressed as a percentage of reading per degree or in PPM (parts per million) per degree.
The average percent of change in output voltage per degree change in temperature with load and input voltage held constant.
The average percentage variation in the output voltage of a SMPS due to temperature variation (specified as parts per million per degree Centigrade, over a specified temperature range).
(1) The ratio of the speeds of a chemical reaction at two temperatures differing by 10°C. (2) A factor relating the response characteristics of a device with changes in the ambient temperature.
A factor, which describes the change in a magnetic property with change in temperature. Expressed as percent change per unit of temperature.
A change in reading (or sourced value) with a change in temperature. It is expressed as a percentage of reading (or sourced value), plus a number of counts per degree change in temperature.
The ratio of a quantity change of an electrical parameter, such as resistance or capacitance, of an electronic component to the original value when temperature changes, expressed in %/ºC or ppm/ºC.
A ratio by which the changes in power supply output voltage caused by temperature changes can be calculated. Usually output decreases as ambient temperature rises.
A constant specifying the amount of change in the value of a quantity for a given chage in temperature.
The amount that the voltage, current, and/or power output of a solar cell changes due to a change in the cell temperature.
The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K (kelvin).
