EXB-2HV912JV is a resistor network or array composed of two high-voltage resistors of the same type. The network is typically used to control the gain of high-voltage applications. It is designed to measure resistance values at different frequencies, enabling the user to determine the correct resistance values for their application. This is important for applications involving noise radiation, such as radio transmitting antennas.

The EXB-2HV912JV is constructed using a 2-resistor daisy-chain structure, which is then enclosed in a protective package. The two resistors are mounted in parallel, and each of them has a nominal value of 912 kΩ. The connection between the two resistors is achieved by a connecting lead, which is connected to the center point of the network. This center point can then be connected to other components of the high-voltage circuit, such as a power switch or voltage signal processor.

The EXB-2HV912JV offers a wide range of resistances, from 0.1 Ω to 10 MΩ, and the resistance value can be set to any level in between. As the voltage increases, the resistance decreases. The resistance values can be adjusted using a potentiometer or trimmer, thus allowing the user to fine-tune the resistance. The network also has the ability to accommodate wide temperature variations, allowing it to be used in applications that require extreme temperatures.

The working principle of the EXB-2HV912JV is based on the Wheatstone bridge principle. In a Wheatstone bridge circuit, two resistors are connected in parallel in order to form a closed loop. When a voltage is applied to the bridge, the two resistive elements across the bridge will have different voltage drops. This difference in voltage drops leads to a current imbalance, which is used to calculate the resistance value across the bridge. By adjusting the resistance values, the current imbalance can be adjusted and, as a result, the resistance value across the bridge can be accurately determined.

The EXB-2HV912JV application field is mainly related to measurements of high-voltage and current applications. It is mainly used in the fields of research and development, or in production processes involving precise resistance levels. The network is ideal for applications such as radio transmitting and receiving antennas, microwave RF circuits, high-voltage cables, and motor drives. Additionally, the network can also be used as a substitute for other resistors in circuits.
