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.

QUICK REFERENCE DATA

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

C in oil.

2. Valid for all types with the exception of 2322 640 5.474.
