Vishay BCcomponents NTC Thermistors, Glass Encapsulated Miniature Bead Document Number: 29061 For technical questions contact: nlr.europe@vishay.com www.vishay.com Revision: 10-Oct-03 121 QUICK REFERENCE DATA 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. PARAMETER VALUE Resistance value at 25 °C1 kΩ to 1 MΩ Tolerance on R25-value ±5%; ±10% B25/85-value 2075 to 4100 K Tolerance on B25/85-value ±5% Maximum dissipation at 55 °C 100 mW Dissipation factor ≈1.2 mW/K Response time; note 1 ≈1 s Thermal time constant ≈10 s Operating temperature range: at zero dissipation −55 to +200 °C or −55 to +300 °C at maximum dissipation 0 to 55 °C Dielectric withstanding voltage (RMS) between terminals and glass envelope min. 1 500 V Insulation resistance between terminals and glass envelope at 100 V min. 100 MΩ Mass ≈0.27 g MARKING The thermistors are marked with four colored dots on the glass envelope; see Component Outline drawing and Electrical Data and Ordering Information table. MOUNTING By soldering in any position. PACKAGING The thermistors are packed in cardboard boxes; the smallest packaging quantity is 100 units. FEATURES • Small diameter • Quick response to changes in temperature • High stability over long time periods • High temperature operation • Resistant to aggressive environments • High degree of isolation between tip and environment APPLICATIONS Temperature measurement and control. Bead thermistor with negative temperature coefficient, in a glass envelope with two tinned durnet (CuNiFe) leads. The device is non-flammable. ELECTRICAL DATA AND ORDERING INFORMATION Note 1. Dependent upon R25-tolerance, the dot IV is coloured as follows: a) for R25 ±5%, dot IV is coloured gold; b) for R25 ±10%, dot IV is coloured silver. 2. R25-values, temperature coefficients, catalog numbers and coding. 3. The thermistors have a 12-digit catalog number starting with 2322 626 1. The subsequent 4 digits indicate the resistance and tolerance. R25 (kΩ Ω Ω Ω) B25/85-VALUE TC (%/K) MAX. TEMPERATURE (°C) CATALOG NUMBER 2322 626 1....
