4820P-2-273LF

Application field

The 4820P-2-273LF is a series array with two resistors in series, each with a value of 136.5 ohms. The application field that the 4820P-2-273LF is primarily used in is audio equipment such as musical instruments, microphones and preamps. As a result of its low total resistance, it is used as an input coaxial cable for audio equipment that requires low-level signals that can be transmitted over long distances, or as a high-frequency crossover, due to the fact that its parallel resistance is much lower than its serial resistance. The 4820P-2-273LF can also be used in telecommunications and antenna systems, providing filter resistors that can reduce the signal attenuation.

Working principle

The 4820P-2-273LF works by connecting two resistors in a specific set pattern. It has two resistors in series, each with a resistance of 136.5 ohms, producing a total resistance of 273 ohms. By connecting the two resistors in a series, the total resistance of the two resistors increases and the current in each resistor is the same. This makes it possible to transmit low-level signals over long distances, as low-level signals need less current than higher-level signals.

A resistor network also allows currents of different frequencies to pass differently through the network. This is due to the fact that high-frequency currents experience greater attenuation when they pass through the resistor network, while low-frequency currents experience less attenuation. This means that the 4820P-2-273LF can be used as a high-frequency filter, blocking higher-frequency currents while allowing lower-frequency currents to continue through the resistor network.

The 4820P-2-273LF is also capable of providing protection to sensitive components that may be connected to it, as its series resistance limits the current that can flow through the components, and its high parallel resistance prevents unwanted current from passing through. It also helps to reduce the risk of overvoltage or short circuits due to its high resistance, ensuring that the components connected are safe and secure.

Overall, the 4820P-2-273LF is a versatile resistor network that can be used in a variety of applications. Its application field and working principle make it an ideal solution for audio equipment, telecommunications, antenna systems and more.
