Overview
The Bourns MF-R600-AP-99 is a radial leaded PPTC resettable fuse from the Multifuse MF-R/600 series. It features a holding current of 6 A and a trip current of 12 A, with a maximum voltage rating of 30 V. The device has a maximum resistance of 20 mOhms and can withstand a maximum fault current of 40 A. It operates within a temperature range of -40°C to +85°C. Physical dimensions include a length of 19.3 mm, width of 7.6 mm, and height of 31.9 mm, with a lead spacing of 10.2 mm.
Feature Summary
- Provides automatic circuit protection against overcurrent conditions through positive temperature coefficient polymer technology.
- Offers reliable resettable functionality without requiring manual replacement after fault clearance.
- Designed for PCB mounting with radial leads for straightforward integration into electronic assemblies.
Applications
- Consumer electronics power supply circuits
- Industrial instrumentation input protection
- Telecommunications equipment surge suppression
Procurement Notes
Verify the specific suffix AP-99 against official Bourns documentation to confirm packaging and compliance details. Ensure the ordering quantity aligns with manufacturer minimums and reel specifications. Confirm RoHS status directly from the latest datasheet as regulatory requirements may evolve. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when a 6 A holding current and 30 V maximum voltage are required for circuit protection. Consider the 20 mOhms resistance for low-power loss applications. Evaluate the radial lead configuration for compatibility with existing PCB footprints. Verify that the operating temperature range meets the environmental demands of the target application.
Part Context
This part belongs to the Bourns Multifuse MF-R/600 series of resettable fuses. These devices utilize PTC technology to provide overcurrent protection in various electronic systems. The series is known for its reliability in consumer and industrial applications where repeated fault events may occur.
Replacement Considerations
Consult official Bourns substitution guides for verified alternatives. Generic equivalents may not match the precise electrical characteristics or physical dimensions. Ensure any substitute maintains the same voltage, current, and thermal ratings.
FAQ
What is the difference between holding current and trip current for this fuse?
Holding current (6 A) is the maximum current the device will allow without tripping. Trip current (12 A) is the minimum current that will cause the device to switch to a high-resistance state.
Is this component suitable for automotive applications?
While Bourns offers automotive-grade components, this specific MF-R/600 series part should be verified against AEC-Q200 compliance requirements if used in automotive environments.
