Through Hole Resistors are a type of passive component that utilize a special design or coating so as to produce a predetermined amount of electrical resistance. In order to provide specific levels of accuracy or stability, resistors may also receive special treatments or unique packaging styles. Resistors come in a variety of shapes and sizes; they may be mounted on printed-circuit boards, or be embedded functions. In this article, we will discuss the application field and working principle of RNX0252M20JNR8.

The RNX0252M20JNR8 resistor is a through-hole resistor with a rating of 5W that can handle up to 8A. It is composed of a copper-clad steel core, with a thin resistor coil located around the steel core. The resistor coil is securely wrapped and secured by a ceramic glue that ensures the tightness of the coil. It is then encased by an epoxy body to provide insulation, protection, and longevity. The RNX0252M20JNR8 resistor is offered in axial-style packaging various sizes.

The RNX0252M20JNR8 is ideal for commercial applications where power handling and accuracy requirements are moderate. It is typically used in rectifier bridges, power supplies, HID/fluorescent ballasts, motor speed control circuits, current-sensing circuits, and other applications of medium power and size. The electrical resistance of the RNX0252M20JNR8 is largely dependent upon the number of windings, the type of material used and the temperature at which the resistor is to operate.

The working principle of the RNX0252M20JNR8 is quite simple yet effective. It functions by converting electrical energy into heat energy. As the current passes through the resistor, it is converted to heat, which is then released into the surrounding environment. The rate at which the heat is released is determined by the resistance of the material, which is determined by the number of coils, and the type of material used. Since the resistor is encased in a protective epoxy body, a significant amount of heat can safely be dissipated.

In conclusion, by utilizing a copper-clad steel core and a special resistor coil with a ceramic glue, the RNX0252M20JNR8 provides heightened stability and accuracy over standard resistors. It is designed for commercial applications where power handling and accuracy requirements are moderate, and is ideal for use in rectifier bridges, power supplies, HID/fluorescent ballasts, motor speed control circuits, current-sensing circuits, and other applications of medium power and size.
