Through Hole Resistors are passive components with resistance in the range of milliohms to megohms. The CFR200J390R is a through hole resistor that has been designed to operate with dissipation power of 200mW, operating temperature range from -55°C to +125°C, and rated voltage in the range of 15 to 25V. It is available in three different types: axial lead, foil lead, and radial lead.

The CFR200J390R is specifically designed for applications requiring high precision resistance. It can be used in a number of applications, such as electric motors, power supplies, and industrial measuring instruments. The resistor is commonly used in circuits for protection, voltage supply, and current limiting. It can effectively alter the magnitude of current passing through a circuit, providing control over current levels.

The CFR200J390R provides excellent thermal stability, accuracy, and reliability. The resistor is constructed from a combination of materials, such as alumina oxide and metal layer deposition. It is also made with a thick-film resistive layer to give high precision and dependable performance over an extended operating temperature range. The foil layer is made with a superior type metal and offers a broad resistance range.

The CFR200J390R´s working principle is based on Ohm\'s law. Its resistance increases with an increase in temperature. This temperature coefficient of resistance (TCR) can be adjusted using different combinations of metallic layers in the resistive layer. For example, if the TCR needs to be within ± 5 ppm/°C, then four metallic layers made of nickel, copper, silver and tungsten are used in the resistor. The combination of these layers provides a temperature range of up to 125°C.

The CFR200J390R has been designed with a low-impedance lead frame, which helps to reduce contact resistance and improve the stability of its performance. It also features an improved electrical contact that reduces contact resistance and ensures better protection of the resistive layer. Furthermore, the resistor is protected with a high insulation strength that helps to prevent short circuits and increase the life of the resistor.

The CFR200J390R is available in three different packages, each with their own particular advantages. The axial lead package is suitable for surface mount and through hole applications, and it is typically used in tiny packages and devices that require high accuracy and corrosion resistance. The foil lead package is designed for medium-power and high-precision applications, and it is suitable for printed circuit boards. Finally, the radial lead package is designed for large-power applications in heavy-duty or outdoor environments.

In conclusion, the CFR200J390R is an ideal resistor for applications that require high precision resistance and reliable performance. Its combination of materials, thick-film layer, and improved electrical contacts make it an excellent choice for many applications. It is available in three different packages, each with their own particular advantages. With its high thermal stability, accuracy, and reliability, the CFR200J390R is an ideal choice for many applications.
