| 2322 640 90042 Vishay BCcomponents NTC Thermistors, Steel Capped Sensors FEATURES * High mechanical strength * AMP connectors for easy connection * Excellent accuracy over a wide temperature range APPLICATIONS * Sensors for water temperature control in, for example: - washing machines - dish washers - heat pumps QUICK REFERENCE DATA PARAMETER Resistance value at: 0 C 25 C 85 C 100 C B25/85-value Temperature coefficient Maximum dissipation Dissipation factor: in still air (for information only); note 1 in still water (for information only); note 1 Thermal time constant (t) in still air; note 1 Response time; note 2 Temperature gradient; note 3 Operating temperature range: at zero power; continuously at zero power; peak at maximum power Minimum dielectric withstanding voltage (RMS) between terminals and capsule during: 1 minute 10 seconds Minimum insulation resistance between terminals and capsule at 100 V (DC) Mass Notes 1. Measured with AMP connectors in still air with solid copper wires of 1 mm diameter. 2. The response time is the time necessary to change 63.2% of the total difference between the initial and the final body temperature, when subjected to a step function change in ambient temperature. Step change: a) initial temperature: air at 25 C b) final temperature: water at 100 C. 3. The temperature gradient is the difference per degree Celsius between the true temperature of the liquid (water) and the temperature measured by the sensor. VALUE 35875 7% 12000 4% 1475 3% 963 4.2% 3730 K -4.2%/K 250 mW 7.5 mW/K 18 mW/K 285 s 13 to 16 s 0.02 K/K -25 to +110 C 130 C 0 to +55 C - electric boilers. These thermistors have a negative temperature coefficient. The device consists of a ceramic material which is mounted in a capsule of stainless steel and provided with two 6.3 mm tinned bronze spade connectors. The device is non-flammable and the housing is stainless steel in accordance with "DIN 1.4301" (x 5 CrNi 18 9). MOUNTING Connect to two FASTONS 6.3 x 0.8 or equivalent. PACKAGING The thermistors are packed in cardboard boxes; the smallest packaging quantity is 50 units.
