PTC Resettable Fuses

PTC (positive temperature coefficient) resettable fuses are designed to detect and interrupt excessive currents that might damage operating systems. This type of circuit-protector features a safety mechanism that helps protect against both short circuit and overload conditions. The main component of such devices are thermistors, which increase their electrical resistance as temperatures rise. These fuses are self-resetting and have the capability to go back to their normal electrical state after the over-current fault has been removed. The B59950C0130A070 resettable fuse is a type of PTC fuse that has a wide range of applications and provides excellent protection against high-current faults.

Application Field

PTC resettable fuses, such as the B59950C0130A070, are widely used in various electronic devices, such as computers, electronics, consumer appliances, medical equipments, and industrial automation systems. They can be used in circuits to prevent overloads, shorts, and other types of electrical faults. This type of fuse is also widely used in battery-operated devices, such as laptops, cell phones, tablets, etc., as it provides protection against over-voltage and over-charging errors.

Working Principle

The B59950C0130A070 resettable fuse is a type of PTC resettable fuse. Its working principle is based on the ability of a thermistor (PTC) to change its electrical resistance with temperature. When the current through the device exceeds a preset threshold, the temperature of the device increases, which in turn increases its electrical resistance. This, in turn, reduces the amount of current passing through the device and thereby reduces the risk of damage to the circuit.

When the fault current is removed, the fuse cools down, and its electrical resistance decreases, allowing the normal operation of the connected electronic system. This resettable functionality of the fuse makes it very useful in case of sudden faults, as it can detect and interrupt the excessive current without the need for manual replacement.

The B59950C0130A070 resettable fuse is offered with a variety of options, such as adjustable trip current values, a wide operating temperature range, and low self-resistance values. These features make the device suitable for a wide range of applications in which it is necessary to protect the involved systems from short circuit and overload conditions.

Conclusion

The B59950C0130A070 resettable fuse is a type of PTC (positive temperature coefficient) resettable fuse that provides excellent protection against high-current faults. It has a wide range of applications, including computers, electronics, consumer appliances, medical equipments, and industrial automation systems. Its working principle is based on the ability of a thermistor (PTC) to change its electrical resistance with temperature. When the current through the device exceeds a preset threshold, the temperature of the device increases, which in turn increases its electrical resistance, thus reducing the amount of current passing through the device. This resettable functionality of the device makes it a very useful protective component.
