4308R-102-104D

Resistor networks, or arrays, are a type of passive components often used to create variable resistance in a circuit. The 4308R-102-104D is a specific type of network that is composed of four two-terminal resistors connected in series and provided in a common package. It is widely known for its ability to reduce the effects of external electromagnetic interference (EMI) or the circuit’s own EMI radiation in small portable devices.

The 4308R-102-104D features a low resistance value of 102 Ohms, with a maximum error of ±1.5 ohms. Additionally, it offers excellent environmental resistance due to its nitrogen-filled construction. This construction also helps it to resist joint corrosion and vibration-related damage, making it a good choice for automotive applications. Its basic mechanical strength also makes it suitable for applications in which low-profile components must withstand higher forces.

4308R-102-104D resistors are typically used in a circuit as an EMI reduction element. Due to the network’s low resistance values, the series resistance creates a stronger counterforce to the EMI radiation present in the circuit, and thus effectively reduces the amount of noise in the circuit. This resistor network is particularly useful in small portable devices, as the low profile of the components also helps to reduce board space.

The 4308R-102-104D works based on Ohm’s law, which states that the resistance of a conductor is equal to the ratio of the voltage applied across it, divided by the current flowing through it. Thus, the four resistors in the network will all be of equal resistance, creating a total resistance of 102 ohms. As the voltage increases, the current passing through the network will also increase, which will in turn increase the amount of noise that is reduced.

Due to its low resistance value, excellent environmental resistance, and low profile, the 4308R-102-104D makes an excellent choice for EMI reduction applications in a variety of electronic devices. Its ability to reduce noise and interference makes it a reliable and cost-effective solution for many applications.
