CRA04P083390RJTD

CRA04P083390RJTD is a high performance 4-Unit resistor array manufactured by Stackpole Electronics Inc., a global leader in the resistors and resistive components industry. The array is constructed with a stack of four individual thin-film resistors, which are integrated and configured to create a unified device. This stack of four offers an improved level of precision and accuracy in resistive networks configurations and applications.

Application Field

The CRA04P083390RJTD array is designed to meet the requirements of a wide variety of applications, particularly those involving precision network designs. With its superior long-term stability and precision, the array outperforms conventional resistor networks in applications such as precision gain sensing and filtering. In many cases, the improved accuracy of the array makes the size and complexity of a resistor network much smaller than with standard resistors, resulting in improved space and cost savings.

The array is ideal for high-frequency analog-to-digital converter (ADC) designs as its wide operating range of up to 12 0dBm ensures higher levels of precision and accuracy over narrower operating range networks. Additionally, its low leakage current of up to 0.25 nA also ensures that circuitry remains free from any disturbances caused by static interference. The array is also suitable for use in pre-amplifiers and post-amplifiers, as its high frequency response up to 3.5 GHz and high power rating to 80 W allows for greater levels of precision in circuit designs.

Work Principle

The CRA04P083390RJTD array features a unique and very efficient form of resistor construction that improves the performance and characterizing capability of the device. The array arranges four resistors in a stacked configuration where each corresponding resistor in the stack is interconnected with the same common, resistor pad. This combination of interconnected resistors provides a highly accurate, piecewise linear resistance value for the array.

The stack of four allows the array to be configured in several types of networks, such as non-isolated, four-terminal, and isolated resistor networks, which all provide distinct advantages to other conventional designs. Each of the four resistors contained in the resistive network has a precisely labelled resistance value, providing precise control of resistance characteristics and accuracy.

Additionally, the CRA04P083390RJTD array features a low temperature coefficient of resistance (TCR) value of ±15 ppm/°C introduced by the aluminum-titanium-silicon (ATS) film and an absolute tolerance of ±0.1%. Its ultra-low noise level of up to 10nV/square root of Hertz also ensures that noise and signal integrity are maintained in a range of precise circuit designs.

Conclusion

The CRA04P083390RJTD array offers excellent performance and accuracy in its precision network designs, outperforming conventional resistors in many cases. Its wide operating range and low temperature coefficient of resistance ensure exceptional accuracy and stability over longer periods of time. Additionally, its high frequency response, high power rating, and ultra-low noise level make the array ideal for a wide range of applications across a variety of industries.
