Fuses FUZETEC RESET-ABLE SELECTION GUIDE For all FUZETEC™ polymeric PTC reset-able 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 reset-able fuse's Electrical Characteristics table and Thermal De-rating Curve to select an appropriate product (series and part number). Ensure the Maximum Operating Voltage and Maximum Operating Current of the selected reset-able fuse exceed the circuit's. Verify that the Time-To-Trip curve to make sure that the selected reset-able fuse is able to protect the circuit "in time". Make sure that physical dimension of the selected reset-able fuse fits into the circuit space. Test and evaluate the selected reset-able fuse; and determine the suitability of the selection.
