PTC selection method and steps Step 1: Determine the circuit parameters You need to determine the following parameters of the circuit: Maximum working environment temperature Standard working current Maximum working voltage Maximum interrupting current PTC devices use a reduction ratio [ambient temperature (° C) holding current (A)] table and select the temperature that best matches the maximum ambient temperature of the circuit. Browse this column to see values that are equal to or greater than the standard operating current of the circuit. Now look at the far left of the row to see the device family best suited for this circuit. Step 3: Compare the maximum electrical rating of the selected device to the maximum operating voltage and interrupt current of the circuit.Use the electrical characteristics table to verify that the part you selected in step 2 will use the maximum operating voltage and interrupt current of the circuit. . Check the device's maximum operating voltage (Vmax) and maximum interruption current (Imax). Ensure that Vmax and Imax are greater than or equal to the maximum operating voltage and maximum interrupt current of the circuit. Step 4: Determine the action time. The action time is the amount of time it takes to switch the device to a high resistance state when a fault current passes through the device. In order to provide the desired protection function, it is important to know the operating time of the PTC device. If the device you select moves too fast, it may cause abnormal or erroneous operation. If the device moves too slowly, the protected device may be damaged before the device moves and limits the current. Use the typical operating time curve at 25 ° C to determine whether the operating time characteristics of the PTC device can be accepted under the expected fault current. If not, go back to step 2 and choose another alternative device. Step 5: Verify the ambient operating temperature Ensure that the minimum and maximum ambient temperatures for the application are within the operating temperature range of the PTC device. Most PTC devices have an operating temperature range of -40 ° C to 85 ° C, and in some special cases can reach 125 ° C. Step 6: Verify the external dimensions of the PTC device Use the external dimensions table to compare the external dimensions of the PTC device you selected with the space conditions of the application.
