| 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 Resistance value at 25 C Tolerance on R25-value B25/85-value Tolerance on B25/85-value Maximum dissipation at 55 C Dissipation factor Response time; note 1 Thermal time constant Operating temperature range: at zero dissipation at maximum dissipation Dielectric withstanding voltage (RMS) between terminals and glass envelope Insulation resistance between terminals and glass envelope at 10 V (DC) Mass 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. -55 to +200 C or -55 to +300 C 0 to 55 C min. 100 V min. 10 M VALUE 1 k to 1 M 5%; 10% 2075 to 4100 K 5% 100 mW 0.8 mW/K 1 s 7.5 s Temperature measurement and control up to 300 C. Bead thermistor with negative temperature coefficient, in a glass envelope with two tinned durnet (CuNiFe) leads. The device is non-flammable. MOUNTING By soldering in any position. PACKAGING The thermistors are packed in cardboard boxes; the smallest packaging quantity is 100 units. 33 mg ELECTRICAL DATA AND ORDERING INFORMATION R25 (k) 1 2.2 4.7 10 22 47 100 220 470 1000 Note 1. R25-values, temperature coefficients and catalog numbers. 2. The thermisters have a 12-digit catalog number starting with 2322 626 2. The subsequent 4 digits indicate the resistance value and tolerance.
