For on-board sensing or accurate remote sensing DESCRIPTION These thermistors are made of NTC ceramic material. The device consists of a chip with two tinned nickel leads. The parts are coated and color band marked. Tape and reel versions available on request. s PACKAGING g The thermistors are packed in cardboard boxes; the smallest packing quantity is 500 units. 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. Thermal time constant by cooling from electrically pre-heated body (2) Valid for all types with the exception of the R 25 values 12 kΩ, 22 kΩ and 470 kΩ DESIGN-IN SUPPORT For complete curve computation, please visit: www.vishay.com/thermistors/ntc-curve-list/. MARKING The thermistors are marked with color bands on a grey epoxy base coating; see Dimensions and “Electrical Data and Ordering Information”. MOUNTING By soldering in any position. Not intended for potting. ELECTRICAL DATA AND ORDERING INFORMATION R25 (Ω) UL CODING SAP MATERIAL NUMBER SAP MATERIAL NUMBER R25-TOL. B25/85 B25/85-TOL.
