<TABLE width="739" border="0"> <TR> <TD> Use the following steps to select a product for the circuit to be protected: (1) Choose the appropriate product construction type based on PCB Design Considerations ： Dip type or SMD type or others. (2) Choose a voltage rating: a PPTC device should be chosen with a voltage rating that equals or exceeds the source voltage in a particular circuit. Also, the expected fault voltage should not be greater than the PPTC voltage rating. For instance 72/30 series. (3) Using the IHold vs.Temperature Table on the product family data sheet, select the polymeric device at the maximum operating temperature with an IHold greater than or equal to the normal operating current. (4) ording 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 num ber). </TD></TR> <TR> <TD> PRODUCT SELECTION GUIDE plete the sheet below based on circuit design, and you will find the model you need: Form: DIP SMD Maximum
