Resistor Networks, Arrays

The 4308H-102-121 is one type of resistor network, sometimes referred to as emitter-coupled resistors or emitter-coupled resistor arrays. This type of resistor network is designed for applications in DC power supplies and can be used in circuits up to 600V and 3A.

These resistor networks are made up of series-connected resistors, which are grouped together into “bins”. Each bin contains multiple resistors in different values. The resistors in each bin are usually connected in parallel and can be either in series or parallel with other bins, depending on the circuit design.

The 4308H-102-121 is an 8-bin resistor network. Each bin is marked from 1 to 8, indicating the size of the resistor in it. The bins consist of two discrete resistor values in two- or eight-bin configurations.

The 4308H-102-121 is a popular type of resistor network for power supplies because it provides the necessary tolerance range and resistance for stable operation. It is also low noise and has low-distortion characteristics.

The 4308H-102-121 is also known for its switching characteristics. Its switching speed is fast, allowing for more accurate and stable power supplies. It can switch from one resistance value to another in just a few microseconds. This helps to keep noise and distortion to a minimum and helps ensure that the power supply stays stable. In addition, the network offers very low-current draw, allowing for more efficient operation of the power supply.

The working principle of the 4308H-102-121 is based on the fact that resistors have a negative temperature coefficient. This means that the resistance increases as the temperature decreases. The 4308H-102-121 uses this property to allow different resistors to be switched on and off, depending on the voltage or load requirements of the circuit. By switching on different resistors, the resistance can be tailored to the needs of the circuit.

The 4308H-102-121 is used in many applications, including DC power supplies, military electronics, and automotive electronics. The resistor array allows for more precise control of power levels and reduces the size and weight of the power supply. Its low noise and low distortion characteristics make it a popular choice for audio and video applications as well.

The 4308H-102-121 resistor network is a reliable and versatile choice for DC power supplies and other applications. It provides excellent robustness and has a wide resistance range, allowing for more efficient operation of the circuit. It is low noise and offers excellent switching characteristics for controlling power levels more accurately.
