| 2381 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 * Old part number was 2322 640 90042 * Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC APPLICATIONS * Sensors for water temperature control in, for example: - washing machines - dish washers - heat pumps - 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). 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.
