FEATURES
• Accuracy over a wide temperature range
• High stability over a long life
• Excellent price/performance ratio
APPLICATIONS
• Temperature sensing and control
These thermistors have a negative temperature coefficient.
The device consists of a chip with two tinned solid
copper-plated leads. It is grey lacquered and colour coded,
but not insulated.
PACKAGING
The thermistors are packed in bulk or tape on reel;
see code numbers and relevant packaging quantities.
