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.
PACKAGING
The thermistors are packed in cardboard boxes; the
smallest packing quantity is 500 units.
DESIGN-IN SUPPORT
For complete curve computation, please visit:
www.vishay.com/en/thermistors/ntc-rt-calculator/.
MARKING
The thermistors are marked with color bands on a gray
epoxy base coating; see Dimensions 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. 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
CAUTIONS AND WARNINGS ON MOUNTING
AND HANDLING
Please read the special instructions:
see www.vishay.com/doc?29222.
By soldering in any position. Not intended for potting.
