2322 640 5.... Vishay BCcomponents NTC Thermistors, Accuracy Line FEATURES • Accurate over a wide temperature range (tolerance on B-value between 2.5% and 0.5%) • Good stability over a long life • Excellent price/performance ratio • Flexible leads • Low heat conductivity through 0.4 mm diameter Ni-leads APPLICATIONS QUICK REFERENCE DATA PARAMETER • Temperature sensing and control. VALUE Resistance value at 25 °C Tolerance on R25-value Tolerance on B25/85-value Maximum dissipation Dissipation factor δ Response time; note 1 Thermal time constant τ Operating temperature range at: zero dissipation (continuously) zero dissipation (for short maximum dissipation (100 mW) Climatic category Mass 2 to 470 kΩ ±5%; ±3%; ±2%; ±1% ±2.5 to 0.5% 100 mW 2.2 mW/K ≈1.7 s 13 s These thermistors have a negative temperature coefficient. The device consists of a chip with two tinned nickel leads and is colour coded. PACKAGING The thermistors are packed in cardboard boxes; the smallest packing quantity is 500 units. −40 to +125 °C ≤150 °C 0 to +55 °C 40/125/56 ≈0.11 g MARKING The thermistors are marked with coloured bands; see Dimentions and “Electrical data and ordering information” Notes 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. MOUNTING By soldering in any position. 2. Valid for all types with the exception of 2322 640 5.474.
