NTC Thermistors, Special Accuracy
FEATURES
* Excellent accuracy between 25 C and 85 C * High stability over a long life.
APPLICATIONS
* Temperature sensing and control.
QUICK REFERENCE DATA
PARAMETER Resistance at 25 C; note 1 Temperature measurement accuracy (between 25 C and 85 C) Climatic category Maximum dissipation Dissipation factor (for information only) Response time (for information only); note 2 Thermal time constant (for information only) Operating temperature range: at zero dissipation (continuously) at maximum dissipation Mass Notes 1. For values of nominal resistance value and tolerance at intermediate temperatures; see resistance values tables. 2. Response time in silicone oil MS 200/50. This is the time needed for the sensor to reach 63.2% of the total temperature difference when subjected to a temperature change from 25 C in air to 85 C in oil. -40 to +125 C 0 to +55 C 0.22 g VALUE 4.7 to 100 k 0.5 C 40/125/56 250 mW 7 mW/K 1.2 s 11 s
DESCRIPTION
These thermistors have a negative temperature coefficient. The device consists of a chip with two tin-plated copper leads. It is grey lacquered and not insulated. These thermistors are very accurate (0.5 C) over a trajectory from 25 C to 85 C.
PACKAGING
The thermistors are packed in cardboard boxes, each box contains 500 units.
MARKING
Grey lacquered body.
MOUNTING
By soldering in any position.
