Description Of Surface Mounted Polymer PTC Resettable Fuse


Polymer Positive Temperature Coefficient (PPTC) Resettable Fuses are overcurrent protection devices used in a wide variety of circuit protection applications. Under fault conditions a PTC's resistance will rise exponentially and remain in a tripped state, providing continuous overcurrent protection until the fault is removed. Once the fault is removed, the power cycled through the device will return to its normal low resistance state.

Fuse or PTC Resettable Fuse ?


The following procedure will help in selecting and applying the correct component. Help is also available from device suppliers. For unbiased advice it is wise to look for a company that offers both fuse and PTC technology.


1. Define the circuit operating parameters. Consider the following: normal operating; current in ampere; normal operating voltage in volts; maximum interrupt current; ambient temperature/rerating; typical overload current; required opening time at specific overload; transient pulses expected; resettable or one-time; agency approvals; mounting type/form factor; typical resistance (in circuit).2. Select a prospective circuit protection component.


3. Determine the opening time at fault. Consult the Time-Current (T-C) Curve to determine if the selected part will operate within the constraints of the application.


4. Verify ambient operating parameters. Ensure that the application voltage is less than or equal to the device's rated voltage and that the operating temperature limits are within those specified by the device


5. Verify the device's dimensions. Compare the maximum dimensions of the device to the space available in the application.
