Ptc Resettable Fuses Procurement Notes

Verify the specific suffix AP-99 against official Bourns documentation to confirm packaging type and compliance status. Ensure the component meets RoHS requirements for your target market. Cross-reference the datasheet for any recent product change notices that may affect specifications or availability. Confirm lead-free soldering compatibility if required by your assembly process.

Ptc Resettable Fuses Selection Notes

Select this component when a 100 mA hold current and 60 VDC rating are required for radial PTC applications. Consider the 4.5 Ohm initial resistance and 380 mW power dissipation limits during thermal design. Evaluate the 40 A maximum fault current capability against potential short-circuit scenarios. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the end application.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns Multifuse MF-R series of resettable fuses. These components utilize polymer positive temperature coefficient technology to provide reusable overcurrent protection. The series is designed for general-purpose electronic circuits requiring reliable, self-resetting safety features without manual intervention after fault removal.

Ptc Resettable Fuses Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Generic PTC fuses with identical electrical ratings may not match physical dimensions or response characteristics. Verify that any substitute maintains the same radial lead configuration and voltage rating.
