Through Hole Resistors

The LR0204F390R is a type of through hole resistor. Through hole resistors, sometimes also known as leaded resistors, are discrete components with metal electrodes or wires that are inserted into the holes of a printed circuit board. In addition to being used as resistors, through hole resistors can also be used for other purposes like isolating different sections of a circuit, providing protection in circuits, and acting as a potential divider.

Through hole resistors come in different sizes, shapes, and materials. The LR0204F390R is an axial leaded resistor made of a special ceramic material which gives it higher resistance values and better thermal stability. It is also designed to fit into a 0.2 inch or 0.3 inch hole in a circuit board and can be mounted with the help of soldering.

Application Field

The LR0204F390R is used in a variety of applications, including:

• Power supplies;
• Amplifiers;
• Circuits for various purposes like high-speed frequency response, signal quality and noise reduction;
• Measurement and controlling devices;
• Protection from overload or short circuit; and
• Data acquisition systems.

The LR0204F390R is also used in various medical equipment as well as audio and video production systems.

Working Principle

The working principle of the LR0204F390R is based on Ohm\'s law, which states that the voltage across a resistor is equal to the product of the resistance and the current. When a voltage is applied to the LR0204F390R, the current will flow in proportion to the voltage applied. The current passing through the resistor then develops a heat which is reduced through the ceramic material. This allows the LR0204F390R to resist higher temperatures and maintain a higher resistance rating than other types of resistors.

The LR0204F390R also has very low self-inductance, which means that it is able to maintain its resistance to a wide range of frequencies and applications. This makes the LR0204F390R a suitable choice for use in circuits that require high frequency response or high level signal quality.

In addition to its resistance and self-inductance, the LR0204F390R also features a wide operating temperature range and long life expectancy compared to other resistors. This makes it an ideal choice for applications that require performance under extreme conditions or long-term operation.

Conclusion

The LR0204F390R is a type of through hole resistor that is used in a variety of applications. It is made of ceramic material which gives it high resistance values and better thermal stability, as well as low self-inductance. It also features a wide operating temperature range and long life expectancy. The LR0204F390R is suitable for use in circuits that require high frequency response or high level signal quality and is ideal for applications that require performance under extreme conditions or long-term operation.
