Surface Mounted Polymer PTC Resettable Fuse
1206 Surface Mount Polymer PTC Resettable Fuse 3216 Metric 0.1A 60V
The 1206 surface mount PTC resettable fuse is one of most popular fuse options
with 3216 metric sized , rated hold current 0.05A up to 3.5A and max voltage up
to 60V.
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.
6. Test the selected product. Independently test
and evaluate suitability and performance in the actual application.
