2322 626 2.... Vishay BCc NTC Thermistors, Glass Encapsulated Miniature Bead FEATURES • Small diameter • Quick response to changes in temperature • Very high long term stability • High temperature operation • Resistant to aggressive environments APPLICATIONS QUICK REFERENCE DATA PARAMETER Temperature measurement and control up to 300 °C. VALUE Resistance value at 25 °C Tolerance on R25-value B25/85-value 1 kΩ to 1 MΩ ±5%; ±10% 2075 to 4100 K Tolerance on B25/85-value Maximum dissipation at 55 °C Dissipation factor ±5% 100 mW ≈0.8 mW/K Response time; note 1 ≈1 s Thermal time constant ≈7.5 s −55 to +200 °C or −55 to +300 °C at maximum dissipation By soldering in any position. The thermistors are packed in cardboard boxes; the smallest packaging quantity is 100 units. 0 to 55 °C Dielectric withstanding voltage (RMS) between terminals and glass envelope min. 100 V Insulation resistance between terminals and glass envelope at 10 V (DC) min. 10 MΩ Mass MOUNTING PACKAGING Operating temperature range: at zero dissipation Bead thermistor with negative temperature coefficient, in a glass envelope with two tinned durnet (CuNiFe) leads. The device is non-flammable. ≈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.
