Fuse Selection Guide
The purpose of this reference guide is to assist engineers to select fuses that will provide effective circuit protection for designated electronic components or equipment.
Factors to consider
1) Select the proper fuse size according to the available circuit space.
2) Select the proper fuse shape according to the mounting method of the circuit.
3) Select the proper fuse according to the product’s required safety certification standards: C-UL, VDE, SEMKO, PSE, CCC, KC, BSI.
4) Determine the proper fuse voltage rating according to the applied voltage of the circuit.
5) Select the appropriate fuse current rating (In) according to the maximum normal working current of the circuit.
- Considered the fuse decaying factors.
- Considered the derating of fuse based on the ambient temperature.
6) Consider the current pulse
- Calculate the circuit’s maximum current pulse I2t value.
- Calculate the required I2t value of fuse.
Time-lag fuse typically is recommended when distinctive current pulse is specified.
7) Select the fuse type.
8) Test run the selected fuse in the circuit/product.
