Resistor Networks, Arrays

The CRC3A4E240JT resistor network is a cost-effective solution for engineers and developers looking to save board space and money. It is an array consisting of two rows and four columns of thin-film metal-oxide resistors. With a maximum voltage rating of 80V, it is suitable for a broad range of applications. In this article, we will discuss the application fields and working principles of the CRC3A4E240JT resistor network.

Application Fields

Due to its low profile, the CRC3A4E240JT is popular in a variety of electronic applications. It is often used for signal routing and bridging in networks that are limited by size and space constraints. Since it features a high impedance, it performs well when used to isolate signals or to dampen low-frequency signals. The CRC3A4E240JT is also often used in battery-powered applications where space must be minimized.

Working Principle

The CRC3A4E240JT resistor network utilizes a thin-film metal-oxide resistor. This type of resistor utilizes a film of a conducting metal, such as aluminum or copper, which is deposited onto a substrate. The resistive layer is then formed by the introduction of oxygen into the metal film, creating an oxide layer that acts as the resistive element. This oxide layer is very thin, allowing the resistor to be much smaller than its wire wound or ceramic-bodied counterparts.

The CRC3A4E240JT is designed to provide a consistent resistance across all resistor elements. This is accomplished by heating each resistor element with a voltage applied across it. The metal-oxide layer is then heated until its resistance reaches the desired value. This ensures that all the resistor elements maintain a consistent resistance, regardless of their position in the array.

Once the resistors have reached the desired value, the network can be used for signal routing and bridging. The CRC3A4E240JT is capable of handling signals up to 80V, allowing it to be used in a variety of applications from isolating signals to bridging high voltage signals.

Conclusion

The CRC3A4E240JT is a versatile and cost-effective resistor network. It is well-suited for applications where space and size are limited, and it can handle signals up to 80V. By utilizing a thin-film metal-oxide resistor, it offers consistent resistance across all elements, making it an ideal solution for signal routing and bridging.
