Functional Features

• Fast acting overcurrent protection
• Resettable fuse functionality
• Surface mount design for easy integration

Advantages and Disadvantages

Advantages: - Resettable fuse feature allows for reuse after fault clearance - Fast acting response to overcurrent conditions - Surface mount design saves space and simplifies assembly

Disadvantages: - Limited maximum current rating compared to some alternatives - May require careful consideration of thermal management in high-current applications

Working Principles

MICROSMD075-2 operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent condition occurs, the device's resistance increases, limiting the current flow. Once the fault is cleared, the device resets itself, allowing normal operation to resume.

Detailed Application Field Plans

MICROSMD075-2 is suitable for a wide range of electronic devices requiring overcurrent protection, including: - Battery packs - Power supplies - LED lighting systems - Consumer electronics

Detailed and Complete Alternative Models

• MICROSMD050-2: Lower hold and trip currents, suitable for more sensitive applications
• MICROSMD110-2: Higher hold and trip currents, ideal for higher power applications
• MICROSMD200-2: Increased maximum current rating for heavy-duty protection needs

This comprehensive range of alternative models ensures that there is a suitable option for various overcurrent protection requirements.
