Overview
The Bourns MF-R500-0-14 is a radial-leaded PTC resettable fuse from the Multifuse MF-R series. It features a 5 A hold current and a 30 VDC maximum voltage rating. The device trips at 10 A and supports a maximum fault current of 40 A. Its initial resistance is 30 mOhms. Designed for PCB mounting, it operates between -40°C and +85°C with a 10.2 mm lead spacing. The component measures 17.4 mm in length, 7.6 mm in width, and 24.9 mm in height.
Feature Summary
- Provides automatic circuit protection through polymeric positive temperature coefficient technology
- Features kinked leads to facilitate secure PCB mounting and mechanical stability
- Offers reusable overcurrent protection that resets automatically after fault clearance
Applications
- Overcurrent protection for portable electronic devices
- Circuit safeguarding in telecommunications equipment
- Protection within automotive electronics systems
- Surge and overload defense in industrial control circuits
Procurement Notes
Verify the specific suffix designation when ordering to ensure correct lead configuration. The zero-one-four suffix indicates kinked leads, which differ from standard straight lead variants. Confirm RoHS compliance status and datasheet revisions prior to final procurement to align with current manufacturing specifications and regulatory requirements.
Selection Notes
Select this component for applications requiring a 5 A continuous operating current and a 30 VDC system limit. Ensure the expected fault current does not exceed the 40 A maximum interrupt rating. Verify that the ambient operating temperature remains within the specified -40°C to +85°C range to maintain reliable tripping characteristics and long-term performance stability.
Part Context
This part belongs to the Bourns Multifuse MF-R series of polymeric resettable fuses. These components utilize conductive polymer technology to provide reliable circuit protection. The series is widely utilized across various industries for safeguarding sensitive electronic components against overcurrent conditions and thermal runaway events.
Replacement Considerations
MF-R500-AP serves as a direct functional substitute with identical electrical ratings but utilizes straight leads instead of kinked leads. Designers must verify that the lead configuration change accommodates the target PCB footprint and mechanical assembly constraints.
