PPTC Resettable Fuses

Information of PPTC
Polymer positive temperature coefficient is referred PPTC. For over-current protector, can palce circuit element. The PPTC element protects the circuit by changing from a low-resistance to a high resistance  state in response to an over current.

The selection tips of PPTC/FUSE

1. Determine the following circuit operating parameters:

Normal operating current – IHOLD 

Maximum circuit voltage – VMAX 

Maximum interrupt current – IMAX

Ambient operating temperature

2. Select the suitable package SMD or DIP.

3. Compare the PTC data sheet ratings for VMAX and IMAX to ensure that the circuit parameters do not exceed these ratings.

4. Verify that the ambient operating temperature within close proximity to the device is within its normal operating range. Thermally derate IHOLD and IMAX as necessary.
