PTC Resettable Fuses are ubiquitous in modern circuit protection devices. They are usually used for short-circuit current protection in various electronic systems. Among these, B59360U0180B010 PTC Resettable Fuses stands out as one of the most reliable and widely used. In this article, their application field and working principle will be discussed.

Application Field

B59360U0180B010 PTC Fuses are ideal for use in preventive circuit protection. There are several application fields in which this component can be used in, including:

• Computer and laptop power circuits
• AC/DC power supplies
• Consumer electronics
• Automotive electronics
• Lighting & LED lighting
• Medical equipment

In each of the application fields mentioned above, the B59360U0180B010 PTC Resettable Fuses can provide efficient protection for both the user and the equipment itself. In computer and laptop power circuits, for example, the fuse can prevent damages caused by short-circuits or electrical spikes that might otherwise occur. The same applies to any of the other application fields previously mentioned.

Working Principle

The B59360U0180B010 Resettable Fuse works on the principle of self-regulation. It is a self-regulating, temperature independent, usually slow-blow, dual-element fuse. A typical configuration consists of two elements which are connected in parallel.

The first element is a polymeric Positive Temperature Coefficient (PPTC) device, and the second element is a conventional fuse link. When the current through the fuse reaches a specified overload current, usually greater then the rated current of the fuse, the PPTC device will enter a temperature-independent resistance state. This will cause the total resistance of the fuse to increase, thus limiting the current. When the current returns to a specified safe level, usually less than the rated current, the fuse will reset itself to its original resistance state.

Conclusion

To conclude, the B59360U0180B010 PTC Resettable Fuses offer great protection for a wide range of electronic applications. They are efficient, reliable and temperature independent. Their working principle is based on self-regulation, allowing it to protect both the user and the equipment itself. As such, these components are ideal for use in any preventive circuit protection.
