Resistor Networks, Arrays refer to a group of resistors interconnected either in series or in parallel to form a network. The CRA12E08330K9FTR is an example of such a network, and this article will provide a detailed look at the application field and working principle of the network.

As a High Voltage, Low Resistance Network, the CRA12E08330K9FTR is used in high voltage power supplies, protection circuits and low voltage DC-DC converters. It is designed to provide a precision voltage divider for current measurements and low resistance measurements in high voltage systems. The resistance value ranges from 1 kOhm to 330 kOhm, allowing a wide range of applications.

The CRA12E08330K9FTR is composed of 12 metal-oxide varistors (MOVs), each with an equal resistance rating of 8.3 kOhm. Each MOV is connected in series with one other MOV, forming a chain of 6 MOVs that are connected in parallel, so that the total resistance of the network is 8.3 kOhm. The individual MOVs are connected to the input and output terminals of the network, and the resulting network creates a voltage divider that can be used to measure current or voltage in high-power systems.

The CRA12E08330K9FTR is designed to provide precise voltage division in high voltage systems, as well as providing protection against high voltage surges. The network is composed of MOVs that act as a surge absorber, so that the voltage divider remains correctly calibrated during periods of high voltage surges. This helps to ensure accuracy and stability of the measurements taken by the voltage divider.

In addition, the network is designed to be highly resistant to electromagnetic interference (EMI). The MOVs are uniformly spaced throughout the network, and the entire network is designed with EMI shielding in mind. This improves the accuracy of the measurements, as well as providing protection against EMI.

The CRA12E08330K9FTR is suitable for use in a variety of applications, including high voltage power supplies, protection circuits, and low voltage DC-DC converters. It provides precise voltage division, along with protection against high voltage surges, and protection from EMI. The network is easy to install and requires minimal maintenance, making it an ideal choice for use in these applications.
