PTC resettable fuses are a type of fuse that automatically resets after a short period of time when it has been tripped. They are commonly used in an array of applications, ranging from home appliances to heavy industrial machinery. The industry standard B59053A0180B020 is no exception, and it has proven to be an incredibly reliable device for protecting sensitive electronic circuits from over current.

Application Field

B59053A0180B020 fuses are most often used in applications where there are high inrush currents or in devices that need to be kept safe from an unpredictable electrical environment. Common applications for this particular PTC resettable fuse include computers, medical equipment, power supplies, data storage devices, and even electric vehicles. It is widely used in the automotive industry where it can help protect car components from voltage spikes or current surges.

It is also an incredibly robust fuse, withstanding up to 125V and 16A at a temperature range of -40℃ to 125℃. The device can also handle many other environmental conditions, such as extreme vibration or shock, and is UL, CUL, and VDE recognized, making it an ideal choice of fuse for many applications.

Working Principle

PTC resettable fuses operate using the principle of positive temperature coefficient (PTC), which states that the resistance of a material increases as its temperature increases. This property is exploited in the fuse, which contains two special components – a PTC element and a heater. The PTC element prevents a high current from passing through the circuit by becoming unstable and thus raising its resistance. The heater then heats up the PTC element, decreasing its resistance, which in turn allows the current to flow through the circuit.

In the case of the B59053A0180B020 PTC resettable fuse, it is manufactured with a glass-filled epoxy tube body, which houses the PTC and heater components. Its design ensures high thermal conductivity and thermal shock resistance, both of which are necessary for effective operation.

Additionally, the fuse also contains an LED indicator that lights up when the circuit is tripped and switches off when it is reset. This ensures that users can easily monitor whether the circuit is functioning properly or not. The fuse also has an easy-to-read current rating, making it easy to identify the correct one for a given application.

Conclusion

The B59053A0180B020 PTC resettable fuse is an incredibly reliable and robust device, and is the industry standard when it comes to protecting sensitive electronic circuits from over current. It is capable of withstanding extreme temperatures, shock, and vibration, and is UL, CUL, and VDE recognized. Furthermore, its design incorporates a LED indicator and an easy-to-read current rating, making it a very user-friendly device.
