Vishay BCcomponents Document Number: 29065 For technical questions contact: nlr.europe@vishay.com www.vishay.com Revision: 10-Oct-03 129 FEATURES • Easy mounting • Rugged construction APPLICATIONS Suitable for many applications, especially when a good insulation and/or a good thermal contact with the chassis is required. Thermistor with negative temperature coefficient and two solid tinned copper leads. The device is mounted in the head of aluminium screws size M4. PACKAGING The thermistors are packed in cardboard boxes; the smallest packaging quantity is 100 units. QUICK REFERENCE DATA Note 1. Measured with screw mounted on an aluminium heatsink of 100 cm2, thickness 1.5 mm, in still air at Tamb = +25 °C. 2. Other R25 values based on 640 0 series are available upon request. 3. Other tolerances on R25 are available upon request. PARAMETER VALUE Resistance value at 25 °C 2.2 kΩ to 470 kΩ Tolerance on R25-value ±5% B25/85-value 3740 to 4570 K Dissipation factor; note 1 ≈23 mW/K Thermal time constant; note 1 ≈7.5 s Operating temperature range at: zero dissipation −40 to +100 °C maximum dissipation 0 to +55 °C Mass ≈1.5 g MARKING The last 4 digits of the catalog number are printed on the stud in accordance with the information in Electrical Data and Ordering Information Table. MOUNTING By means of a washer and M4 nut supplied with the device. Applied torque shall not exceed 1.2 Nm. Leads to be soldered. ELECTRICAL DATA AND ORDERING INFORMATION Note R25-values, temperature coefficients and catalog numbers. The thermistors have a 12-digit catalog number starting with 2322 640 7. The subsequent 4 digits indicate the resistance value and tolerance. R25 (kΩ Ω Ω Ω) B25/85-VALUE TC (%/K) CATALOG NUMBER 2322 640 7....
