Revision: 10-Oct-03 105

FEATURES

•

Accurate over a wide temperature range

•

High stability (tolerance on B-value between

2.5% and

0.75%) over a long life

•

Excellent price/performance ratio

•

For mechanical fixing in a housing or soldering directly to

‘non-standard’ leads

APPLICATIONS

•

Temperature sensing and control.

DESCRIPTION

These thermistors have a negative temperature coefficient.

The device consists of a silver metallized square chip.

PACKAGING

The naked chips are placed in sealed polythene bags and

packed in cardboard boxes. The smallest packaging quantity

is 5000 units.
