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.
