MF-RG900-0-14

Overview

The Bourns MF-RG900-0-14 is a resettable polymeric positive temperature coefficient (PPTC) device designed for overcurrent protection in electronic circuits. It functions as a self-resetting fuse that increases resistance significantly upon detecting excessive current, thereby limiting the flow to safe levels. The component is engineered to provide reliable circuit safeguarding without requiring manual replacement after a fault event, ensuring continuous operational integrity in protected systems.

Feature Summary

• Self-resetting functionality eliminates the need for manual replacement after tripping events
• Polymeric technology provides robust overcurrent protection through rapid resistance increase
• Designed for integration into compact electronic assemblies with standard mounting requirements

Applications

• Consumer electronics circuit protection
• Industrial equipment overcurrent safeguarding
• Telecommunications infrastructure safety
