Through Hole Resistors are electrical components that provide a path for electric current to pass through, creating a resistance to that current. One specific type of through-hole resistor is the MJ1272FE-R52. It is a surface-mount resistor with a built-in fuse element, used in military and medical applications, and is also commonly used in consumer electronics. This article will discuss the application field and working principles of the MJ1272FE-R52.

Application fields of the MJ1272FE-R52

The MJ1272FE-R52 is used in a variety of applications, including military and medical electronics equipment. It is most commonly found in high-power radar systems, missile guidance systems and pulsed power systems. In addition, it is frequently used in medical equipment such as MRI systems and pacemakers, as well as consumer electronics like mobile phones and computers. Its resistance to high voltage and current make it an ideal choice for these applications.

Working Principles of the MJ1272FE-R52

The MJ1272FE-R52 is a surface-mount resistor with a built-in fuse element. Its fuse element is designed to trip when an excessive amount of current passes through it, which helps prevent damage to the device in which it is installed. This is done by a series of metal strips that, when all are connected, form a complete circuit that carries the current. When an excessive current passes through, the metal strips heat up, causing the fuse element to trip and thereby cutting off the current.

The MJ1272FE-R52 is also equipped with an internal fuse indicator that will alert users when the fuse has tripped and needs to be reset. This indicator consists of a small LED display that will light up when the fuse has tripped, allowing users to quickly identify and reset the fuse as necessary.

In addition to the fuse element, the MJ1272FE-R52 also includes a normally-closed thermal switch element, which is designed to detect when the device\'s temperature reaches unsafe levels and shut off the current. This element is typically used in radar systems to prevent damage to the antenna from overheating.

Finally, the MJ1272FE-R52 is capable of withstanding extreme temperatures, meaning it can be used in both high-temperature and low-temperature environments. This makes it suitable for use in medical equipment, military equipment, consumer electronics and other applications where temperature extremes are present.

Conclusion

The MJ1272FE-R52 is a through-hole resistor with a built-in fuse element that is often used in military, medical and consumer electronics applications. It includes a fuse element and a thermal switch element, making it suitable for high-voltage and high-current applications while also providing protection against excessive temperature. Its ability to withstand extreme temperatures makes it an ideal choice for a variety of applications.
