Through Hole Resistors

Through hole resistors are an important component in circuit design. They are used for voltage and current divider circuits, impedance matching, noise filtering and signal conditioning. The LR0204F820R is a type of through hole resistor that offers a range of features and advantages for a variety of applications.

Application Field

The LR0204F820R is suitable for a wide variety of different applications including power management, automotive and consumer electronics. It is commonly used in automotive electronics such as security and entertainment systems, navigation systems, video monitors, and audio systems. It is extremely reliable and has low dissipation characteristics for use in high-performance and power-sensitive applications.

In addition, the LR0204F820R is also used in consumer electronics such as smartphones and tablets, due to its accuracy and low on-resistance. Its low ESR characteristics also make it ideal for use in high-current and high-voltage applications, such as power supplies, motor control, and DC/DC converters.

Working Principle

The LR0204F820R is a three-terminal device. It consists of a thin film resistor with multiple constriction elements and a top electrode, and two side electrodes. The side electrodes can be connected to the device’s input and output pins. When a voltage is applied to the input pin, a current flows through the constriction elements. The current is then output through the output pin. The resistance of the device is determined by the size and number of constriction elements.

The LR0204F820R is designed to dampen AC signals, such as oscillations and high frequency noise. It acts as an LED, preventing the impedance of the device from changing when DC gains are applied. It also acts as a resistive divider, allowing the signal to be amplified by a factor of 10 times.

In addition, the LR0204F820R can also be used as a signal conditioning device, allowing signals to be passed through capacitors or filters to reduce the effects of noise or distortion. This is often used in audio systems or video monitors, where the signal must be cleaned up before it is passed to an amplifier or speaker.

Conclusion

The LR0204F820R is an important through-hole device for circuit design. Its features and low on-resistance make it suitable for a variety of applications, from high-voltage power supplies to consumer electronics. The LR0204F820R can be used as a signal conditioning device, as an LED, or as a resistive divider, allowing signals to be amplified by a factor of 10 times and dampening AC signals.
