Through Hole Resistors are important components in most electrical engineering applications, from simple on/off switches to complex robotics. The 42JR15E resistor is a specialized Surface Mount Technology Through Hole Resistor, designed to provide the highest possible power handling capability in an extremely small component.

The 42JR15E resistor is a high voltage, high power Through Hole Resistor with an operating voltage of up to 15kV. This is an ideal solution for applications where a high voltage or power requirement is needed in a tight space. Commonly used in telecom, medical, and military applications, the 42JR15E provides an ultra-low profile and high-temperature operation.

Surface Mount Technology (SMT) is a method of mounting resistors and other components directly to the surface of a printed circuit board. The technology allows for very small components to be used without the need of a heat sink. Using SMT, the 42JR15E resistor can fit into a much smaller package than other Through Hole Resistors, yet retain its high power handling capability.

The 42JR15E resistor utilizes a unique design to achieve its high power capabilities. Its body is composed of two epoxy-filled ceramic discs mounted on top of each other, with an inner conductive ring and an outer conductive layer. This assembly is then treated with a polymer coating to provide superior corrosion and temperature resistance. This design ensures optimal performance in a variety of extreme environmentally conditions.

The 42JR15E is commonly found in the following applications: air conditioning, electric forklifts, security systems, medical equipment, robotics, and other high voltage/power equipment. The resistor can be used in parallel with other resistors to improve power distribution and reduce the risk of short circuits. It is also suitable for use with higher voltage power supplies and can suppress electrical noise effectively.

The working principle of the 42JR15E resistor is relatively simple and efficient. When a current is applied to the resistor, voltage divides between the inner and outer conducting layers. The voltage then produces an electric field in the resistor, and resistance is created in the form of a current-limiting resistor. The internal magnetic field in the resistor strengthens the resistance further, maximizing power pulsing and thermal shock resistance.

In conclusion, the 42JR15E is a specialized Through Hole Resistor that can be used in applications where intense power and a small size are both important. Its high voltage handling capability and superior resistance make it a popular choice for a wide variety of high power applications.
