Vishay BCcomponents
FEATURES
Accurate over a wide temperature range (tolerance on
B-value between 2.5% and 0.5%)
Good stability over a long life
Excellent price/performance ratio
Flexible leads
Low heat conductivity through 0.4 mm diameter Ni-leads
APPLICATIONS
Temperature sensing and control.
These thermistors have a negative temperature coefficient.
The device consists of a chip with two tinned nickel leads and
is colour coded.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packing quantity is 500 units.
