• Provides automatic circuit protection through reversible thermal response to overcurrent conditions
• Engineered for high-temperature stability suitable for demanding automotive environments
• Utilizes radial leaded construction for reliable PCB mounting and mechanical retention

Applications

• Automotive electronic modules requiring AEC-Q200 compliance
• Low-voltage DC power distribution circuits
• Battery protection systems in electric vehicles
• Consumer electronics requiring high-temperature reliability

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required AEC-Q200 qualification status if used in automotive contexts. Cross-reference manufacturer documentation for any recent product change notices affecting pinout or material composition.

Selection Notes

Select this component when circuit design requires a 2 A holding current with a 16 VDC maximum voltage rating. Consider the 110 mOhms typical resistance for power loss calculations and the 100 A maximum fault current capability for short-circuit scenarios. Evaluate the radial lead spacing and physical dimensions to ensure compatibility with the target printed circuit board layout.

Part Context

This device belongs to the Bourns Multifuse RHT series, which focuses on high-temperature performance for robust circuit protection. The series is designed to replace traditional fusible links in applications where resettable functionality is preferred. It serves as a critical safety component in modern electronic assemblies requiring reliable overcurrent management.

Replacement Considerations

Consult official substitution guides for equivalent PPTC devices with matching 2 A holding current and 16 VDC ratings. Verify that alternative components meet the same AEC-Q200 automotive qualification requirements and maintain compatible physical footprint constraints for direct replacement.
