Temperature Rerating Curve
Wave Soldering
260°C, 10 seconds max.
Note:
1. Rerating depicted in this curve is in addition to the standard rerating of 25% for
continuous operation.
Example:
For continuous operation at 70 degrees celsius, the fuse should be rerated as follows:
I = (0.75)(0.80)I
RAT = (0.60)IRAT
2. The temperature derating curve represents the nominal conditions. For questions
