045106.3MR Application Field and Working Principle

The 045106.3MR resistor is a medium-power fuse used in power electronic equipment and communication systems. It is mainly designed to protect current system and electronic components from damage due to short-circuit, overload, over-temperature or other emergency conditions. It can reduce the risk of system failure or damage caused by overload or short-circuit current, thus ensuring the reliability and safety of the electronic device or system.

Application Field

With its reliable performance and small size, 045106.3MR resistor is widely used in the electronic power industry, especially for communication systems, UPS systems, alarm systems, remote control systems, elevators, industrial automation systems, digital information networks, power distribution systems and other high-level electronic devices. It can also be used in voltage regulation systems, power electronic control systems, lighting systems, magnetic circuit protection systems and other power systems.

Working Principle

The 045106.3MR resistor consists of a fuse element and a fuse holder. The fuse element is a thermal-type fuse, which is made up of a fuse wire, a thermal cut-off switch and other components. When the current passing through the fuse element exceeds its rated current, or when the system is over-loaded, the heat generated by the current will cause the fuse wire to melt and the thermal cut-off switch will be activated, cutting off the current and protecting the system.

When the current is normal, the fuse element and the fuse holder will not cause extra resistance, which will not reduce the performance of the power system. 045106.3MR resistor also has a reset function, which can reset after the current passes through the fuse, and the system can continue to work.

Advantages

The 045106.3MR resistor has excellent performance and is reliable, safe, low-cost, easy to install, long-term and low-maintenance. Its heat-resistant and thermal characteristics are superior to that of other resistors, which makes it suitable for use in high-power electronic devices or systems. In addition, its unique design can effectively reduce the self-heating of the resistor, which can prevent the system from becoming overheated.
