MF-SM200-2-006

PTC Resettable Fuses are recommended for shorter overcurrent protection applications because they have a faster response time and provide longer cycle life than traditional thermal type fuses. These resettable fuses include the MF-SM200-2-006, which is a high current device used in a variety of applications. This article will discuss the application field and working principle of the MF-SM200-2-006 PTC Resettable Fuse.

Application Field

The MF-SM200-2-006 PTC Resettable Fuse has a wide range of applications. It is used as an overcurrent protection device in air conditioning and motor overheating prevention, portable electronic devices, power strips, clamp meters, surge protectors, test equipment, vending machines, and many other applications. It can also be used as a backup fuse in case of a fuse blowout. It can provide overcurrent protection in any situation that does not require a traditional thermal type fuse.

Working Principle

The MF-SM200-2-006 PTC Resettable Fuse operates using a solid-state positive temperature coefficient element. When the temperature of the element reaches a certain level, the resistance will increase, causing current flow to be restricted. This results in the device triggering and the circuit being protected from further damage. When the temperature drops, the device will reset and current flow will once again resume.

The MF-SM200-2-006 PTC Resettable Fuse uses a low temperature coefficient and operates in the 65 to 82 degree centigrade temperature range. The device is configurable so that the hold current and trip current can be set to desired values to ensure that the device works as intended. An integrated overtemperature alarm can be configured to warn the user if the device temperature exceeds the configured value.

Conclusion

The MF-SM200-2-006 PTC Resettable Fuse is an excellent choice for shorter overcurrent protection applications. Its high current capability and configurable trip and hold current settings make it suitable for a wide range of applications. Its solid-state positive temperature coefficient element ensures fast response time and long cycle life, making it an ideal choice for overcurrent protection.
