- Radial through-hole mounting configuration
Applications
- Automotive circuit protection
- Power supply overcurrent protection
- Consumer electronics safeguarding
Procurement Notes
Verify the specific suffix against official Bourns documentation to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required hold and trip current specifications for the target application circuit. Confirm AEC-Q200 compliance requirements are met by the specific part number before procurement.
Selection Notes
Select this component for circuits requiring robust overcurrent protection in high-temperature environments. The 2 A hold current and 16 VDC rating suit low-voltage automotive and industrial systems. Verify that the 110 mOhms resistance does not impact signal integrity or power loss constraints in the design.
Part Context
This part belongs to the Bourns Multifuse MF-RHT series of polymer positive temperature coefficient devices. These resettable fuses provide automatic circuit protection by increasing resistance significantly upon overheating. The series supports various hold currents and voltage ratings for diverse electronic protection needs.
Replacement Considerations
Consult official Bourns substitution guides for direct equivalents. Generic PPTC fuses may lack AEC-Q200 qualification or identical thermal characteristics. Verify dimensional compatibility and electrical parameters before substituting with other manufacturers' products.
FAQ
