PTC resettable fuses have become an increasingly important part of electronic design over the last few years. In the past, fuses were used to protect circuits from over-current, however, their single-use nature meant that they had to be replaced or reset after each fault. The advent of the PTC resettable fuse has allowed electronic designers to improve circuit protection, while also integrating it into a more adaptable system. There are a variety of PTC resettable fuse technologies on the market, each with their own unique advantages and capabilities. One such technology is the RUEF185 application field and working principle.

The RUEF185 is a high-performance, high-power PTC resettable fuse. It is designed to provide designers with a cost-effective, reliable solution for circuit protection. The fuse is composed of two parts; the vent and the body. The vent works to stabilize the pressure on the fuse, while the body houses the actual PTC element and provides a conduction path to the other terminals. The PTC element is the heart of the device and works to detect and suppress any over-current or short-circuit events.

The RUEF185 works on the principles of thermal shutdown. When a current overload is detected, the resistance of the PTC element begins to rise. As the resistance rises, the current is limited, and the temperature rises. Once the temperature reaches a preset limit, the device trips, and the current path between the fuse terminals is broken. After the overload has been cleared, the device self-resets and the current path is re-established. This self-resetting capability means that the device can be reused indefinitely, eliminating the need for costly replacements.

The RUEF185 is designed to be used in high-power applications. It is rated for up to 185 amps at 65°C and is capable of providing protection up to 600V. It is also much more compact than traditional fuses, making it ideal for space-constrained applications. The device is also designed to provide reliable protection during high-speed switching applications, making it well-suited for automotive and industrial control applications. Furthermore, the fuse is UL approved and RoHS compliant, making it a safe and reliable choice for designers.

The RUEF185 is a reliable and cost-effective solution for providing circuit protection. Its self-reset capability makes it well-suited for a wide range of high-power applications, while its compact design makes it ideal for space-constrained systems. Furthermore, its UL approval and RoHS compliance provide peace of mind that it is a safe and reliable device. For designers who are looking for a high-performance PTC resettable fuse solution, the RUEF185 is an ideal choice.
