Overview
The Bourns MF-R700-AP-14 is a radial leaded PTC resettable fuse from the MF-R series, rated for 30 VDC and 7 A hold current. It features a maximum trip current of 14 A and a maximum fault current rating of 40 A. The device exhibits a minimum resistance of 20 mohms and operates within a temperature range of -40°C to +85°C. It utilizes a bulk packaging format with a 10.2 mm lead spacing.
Feature Summary
- Provides automatic circuit protection through self-resetting polymer positive temperature coefficient technology
- Designed for PCB mounting with radial leads for standard through-hole integration
Applications
- General electronics overcurrent protection
- Automotive circuit safeguarding
- Power supply input protection
Procurement Notes
Verify that the specific AP-14 suffix corresponds to the required tape and box packaging configuration rather than bulk units. Confirm the component status remains active in the manufacturer's current production list before finalizing procurement plans. Ensure the voltage and current ratings align precisely with the target circuit requirements.
Selection Notes
Select this component when high current handling up to 40 A is required alongside a 7 A continuous operating limit. The radial package facilitates easy insertion into printed circuit boards. Consider the 20 mohms initial resistance impact on low-voltage circuits. Evaluate the thermal environment to ensure operation stays within the specified -40°C to +85°C range.
Part Context
This part belongs to the Bourns MF-R series of high-current resettable fuses. These devices utilize polymeric positive temperature coefficient materials to provide reliable overcurrent protection. The series is engineered for applications requiring robust surge handling and repeated tripping capabilities without permanent damage.
Replacement Considerations
Consult official Bourns documentation for parametric equivalents. Verify that any substitute maintains the 30 VDC rating, 7 A hold current, and radial lead configuration to ensure mechanical and electrical compatibility.
