PTC Resettable Fuses

PTC resettable fuses are self-recovering polymeric positive temperature coefficient (PPTC) Fuses. They are designed to protect electronic equipment from current surges and are now being used in industrial and consumer applications. PTC resettable fuses provide a cost-effective solution to a range of power supply and equipment protection problems. They offer the advantages of low cost, flame retardant construction, improved reliability, and easy installation. The B59950C0080A070 is a typical example of a PTC resettable fuse.

Application field

The B59950C0080A070 resettable fuse is commonly used in a variety of consumer electronics, such as TVs, computers, DVD players, and appliances. It may also be used in industrial equipment, such as Over-current Protection. Since PTC resettable fuses are self-recovering, they can be used in a wide variety of applications where standard fuses would quickly fail and require the user to be present to reset the fuse.

Working Principle

The B59950C0080A070 resettable fuse uses a polymeric PTC element which is a temperature sensitive device. As the temperature increases, the resistance of the element increases, limiting the current. When the current is too high, the PTC element will heat up and open the circuit. Once the current is reduced, the element will cool off and the fuse will reset itself. The device also has a fail-safe feature which prevents the device from being reset if the current is too high. The user must manually reset the device when the current is within range.

Advantages

The B59950C0080A070 resettable fuse has several advantages. It is more reliable than standard fuses and has a longer life. Since the fuse is self-recovering, it doesn’t require the user to be present to reset the fuse, saving time and money. The device is more cost effective since it can be used in a variety of applications. It is also flame retardant and is easy to install.

Disadvantages

The B59950C0080A070 resettable fuse does have some disadvantages. The device can only be used in one application at a time, which can limit its scalability. The device also requires manual resetting, which can be a nuisance for some applications.

Conclusion

The B59950C0080A070 PTC resettable fuse is an ideal solution for applications where a standard fuse would not work. It offers improved reliability and a longer life compared to standard fuses. It is also cost effective, flame retardant, and easy to install.
