NTC Thermistors, Radial Leaded, Accuracy Line
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 R25 values 12 kΩ,
22 kΩ and 470 kΩ
FEATURES
• Accurate over a wide temperature range
(tolerance on B-value down to 0.5 %)
• Good stability over a long life
• Excellent price/performance ratio
• Low heat conductivity through 0.4 mm Ni-leads
• UL recognized, file E148885
• RoHS compliant, available with or without
exemption
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Temperature measurement, sensing and control in
industrial, consumer and telecom applications. 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.
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/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.
