2322 633 0/1.... Vishay BCcomponents NTC Thermistors, Glass Encapsulated Miniature Bead FEATURES • Small diameter • Quick response to changes in temperature • Very high long term stability • High temperature operation APPLICATIONS Temperature measurement, level and flow sensing. Bead thermistor with negative temperature coefficient, having two solid platinum-iridium leads in axial or radial configuration. The device is non-flammable. QUICK REFERENCE DATA PARAMETER VALUE Resistance value at 25 °C Tolerance on R25-value B25/85-value 1 kΩ to 1 MΩ MOUNTING ±5%; ±10% Spot weld the leads to conducting wires or other supports. 2075 to 4100 K Tolerance on B25/85-value Maximum dissipation at 55 °C ±5% PACKAGING 100 mW Response time; note 1 The thermistors are packed in cardboard boxes; the smallest packaging quantity is 100 units. ≈0.5 s Operating temperature range: at zero dissipation −55 to +200 °C Mass ≈33 mg Note 1. Response time in silicone oil MS200/50. 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.
