Overview
The Bourns MF-R800-AP-14 is a polymeric PTC resettable fuse rated for 30V DC with an 8A hold current and 16A trip current. It features radial leads in a disc package measuring 24.20mm x 3.00mm x 32.90mm. The component supports peak currents up to 40A, operates between -40°C and +85°C, and dissipates up to 4W. Initial resistance is minimum 5mΩ, while post-trip resistance is maximum 30mΩ. Trip time at 16A is 18.8 seconds.
Feature Summary
- Provides overcurrent protection through automatic reset functionality using polymeric technology.
- Encased in cured flame-retardant epoxy polymer insulation meeting UL 94V-0 standards.
- Radial leaded construction facilitates through-hole mounting on printed circuit boards.
Applications
- Low-voltage power supply load protection
- Computer and peripheral circuitry
- General electronics equipment
- Automotive applications
Procurement Notes
Verify the specific suffix AP-14 against official Bourns documentation to confirm lead configuration and packaging details. Ensure the selected variant matches the required radial spacing and insulation type. Cross-reference datasheet parameters for voltage and current ratings before integration. Confirm RoHS compliance and halogen-free status if required by project specifications. Validate active part status directly from manufacturer sources.
Selection Notes
Select this component for circuits requiring high holding current capabilities up to 8A. Consider the 30V DC rating for low-voltage system protection. Evaluate the 18.8-second trip time against fault response requirements. Assess thermal dissipation needs within the 4W limit. Verify compatibility with through-hole assembly processes and available board space for the specified dimensions.
Part Context
This device belongs to the MF-R Multifuse series of polymeric resettable fuses. The series provides versatile protection solutions for various electronic applications. The specific model utilizes radial leads and epoxy insulation for durability. It represents a standard solution for overcurrent protection in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include MF-R800-AP and MF-R800-2-14. These variants share identical electrical ratings of 8A hold and 16A trip currents. Verify mechanical dimensions and lead spacing compatibility before substitution. Ensure insulation material and flammability ratings meet original design requirements.
