NTC Thermistors, Glass Encapsulated Miniature Bead

FEATURES

• Small diameter

• Quick response to changes in temperature

• Very high long term stability

• High temperature operation

• Resistant to agressive environments

APPLICATIONS

Temperature measurement.

QUICK REFERENCE DATA

PARAMETER

VALUE

PACKAGING

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.

The thermistors are packed in cardboard boxes; the smallest

packaging quantity is 100 units.

Note

1. Dependent upon R₂₅-tolerance, the dot IV is coloured as follows:

a) for R₂₅±5%, dot IV is coloured gold;

b) for R₂₅±10%, dot IV is coloured silver.

2. R₂₅-values, temperature coefficients, catalog numbers and coding.

3. The thermisters have a 12-digit catalog number starting with 2322 633 2. The subsequent 4 digits indicate the resistance value and tolerance.
