Through Hole Resistors

FCR200JR-73-430K Application Field and Working Principle

Through-hole resistors are an essential cornerstone in any electronics system, and are used for their ability to effectively resist the flow of electricity. Manufacturers often use through-hole resistors to create an electrical circuit that can handle a high level of current. These components are also ideal for high-voltage applications and are often found in large-scale power supply designs.

The FCR200JR-73-430K is an example of this type of through-hole resistor. It is a 200-watt resistor with an operating range of 10-75 volts. The resistance value is 430KΩ, with a tolerance of five percent (5%). The working temperature range for the FCR200JR-73-430K is -55°C to +125°C, and it has a power rating of 7.0W. The dielectric strength is UL (Underwriters Laboratories) approved, making it suitable for use in critical circuits.

The working principles for through-hole resistors are quite simple. When an electric current passes through a resistance, it faces opposition. The opposition is known as the ‘resistance’, and is measured in ohms (Ω). As the current passes through the resistance, it encounters electrical resistance, which leads to the generation of heat. This heat is dissipated by the resistor body, in order to prevent damage to other components in the circuit.

By modifying the size and material of the resistor, the amount of opposition encountered can be adjusted to different levels. This is a very useful feature, as it allows the user to control the level of current running through a circuit. For example, for low-voltage applications, a lower level of resistance may be chosen in order to reduce the amount of heat produced. Conversely, for high-voltage applications, the user may choose a higher level of resistance in order to accommodate the increased current flow.

The FCR200JR-73-430K is ideal for use in a variety of applications, such as home audio systems, battery management systems, and automotive electrical systems. It provides excellent resistance to high levels of current, and is ALT (Advanced Level Test) approved. The resistor is also RoHS compliant, making it suitable for use in most countries.

In conclusion, the FCR200JR-73-430K is a popular through-hole resistor due to its ability to handle high levels of current with low levels of resistance. It is UL rated, RoHS compliant, and ALT approved, making it an ideal choice for a variety of electronics systems. By choosing the correct size and material, the user is able to customize the level of electrical resistance to suit their particular needs.
