FUSETRONIC RESETTABLE SELECTION GUIDE-
For all FUSETRONIC polymeric PTC resettable fuse product, use
the following steps to select a product for the circuit to be protected:
- Based on the application and circuit, select product construction
type: Radial Leaded, Axial Leaded or Surface Mount.
- Determine Operating Voltage, Operating Current, Maximum
Operating Voltage, Maximum Interrupt Current and Maximum
Ambient Temperature for the circuit to be protected.
- According to the circuit's Operating Current, Operating
Voltage and Maximum Ambient Temperature refer to resettable
fuse's Electrical Characteristics table and Thermal Derating
Curve to select an appropriate product (series and part
number).
- Ensure the Maximum Operating Voltage and Maximum Operating
Current of the selected resettable fuse exceed the circuit's.
- Verify that the Time-To-Trip curve to make sure that
the selected resettable fuse is able to protect the circuit "in
time".
- Make sure that physical dimension of the selected resettable
fuse fits into the circuit space.
- Test and evaluate the selected resettable fuse; and determine
the suitability of the selection.
