• Sensitive to ambient temperature variations

Working Principles

The MF-RHT400-0 operates based on the principle of positive temperature coefficient (PTC) behavior. When the current exceeds the trip current, the device heats up, causing its resistance to increase significantly, effectively limiting the current flow and protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-RHT400-0 is widely used in various electronic applications, including: - Power Supplies - Battery Management Systems - Automotive Electronics - Industrial Control Systems - Consumer Electronics

Detailed and Complete Alternative Models

Several alternative models to the MF-RHT400-0 include: - MF-RHT600-0 - MF-RHT200-0 - MF-RHT800-0 - MF-RHT100-0

These alternatives offer varying hold currents, trip currents, and maximum current capabilities to suit different application requirements.

In conclusion, the MF-RHT400-0 resettable fuse offers reliable overcurrent protection with its resettable nature, low resistance, and fast response. While it has limitations in maximum current handling and temperature sensitivity, it finds extensive use in diverse electronic applications. Additionally, there are alternative models available to cater to specific current rating needs.

This comprehensive overview provides valuable insights into the MF-RHT400-0 and its role in electronic circuit protection.
