Application Field

RER70F25R5MC02 is mainly used in fields such as the protected power grids, inverters, control systems, and communication and automotive electronics. It is also used in electronic transformers and regulating power supply systems. Moreover, this product can be used in pulse radio station systems, LED lighting, and medium and high voltage compensation systems. The performance of this product is good in terms of its ability to withstand temperature, high power capability, and stable operation.

Working Principle

RER70F25R5MC02 is a voltage-controlled resistor. It works by controlling the voltage of a circuit and subsequently reducing current flow when an excessive voltage is sensed. It can also reduce the amount of voltage in a circuit by creating a voltage offset or by creating a variable resistance path. The resistance of the circuit can be adjusted by changing the voltage, thus controlling the current.

This product is composed of a metal-ceramic shell and ceramic glazed film. The metal part of the shell serves to dissipate the heat generated by the device during operation, while the glazed film serves as an electrical insulator. The glazed film coating is applied to the inner side of the metal shell to protect the device from environmental degradation. Inside the resistor, ceramic pellets are sandwiched between two layers of metal, forming an insulating dielectric layer that provides thermal stability and maintains the electrical properties of the resistor.

When current runs through the resistor, the heat generated by the electrical current is transferred through the metal layers and dissipated through the outer metal-ceramic shell. The ceramic pellets also act as a barrier to prevent unwanted currents from escaping or entering the device, thus ensuring maximum electrical stability and reliability. This type of resistor has a high power rating and is capable of dissipating large amounts of heat. In addition, its ceramic glazed film coating is very resistant to corrosion and provides excellent resistance to temperature changes.

RER70F25R5MC02 is a high power type, ceramic glazed film resistor with an outer shell made of metal-ceramic. With its good thermal stability, high power capability, and stable operation, it has wide applications, from protected power grids to LED lighting.
