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.
(2)
Valid for all types with the exception of the R25 values 12 k,
22 k and 470 k.
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
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
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.
PACKAGING
The thermistors are packed in cardboard boxes; the
smallest packing quantity is 500 units.

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.
