Working Principle of CRB3A4E102GT

CRB3A4E102GT is a common four-terminal resistor network. Its working principle is similar to other resistor networks, in that it relies on the adjustable ratio of the resistors to achieve a desired effect. It is based on a mixed technology consisting of thin film resistors on one side to improve its performance and on the other side, a standard resistance network. The thin film resistors are connected in parallel to match the output current and voltage. This allows the CRB3A4E102GT to maintain accuracy and stability over a wide range of varying power supply voltages.

The adjustable resistor ratios of the CRB3A04E102GT are based on the linear law associating the ratio of a resistor\'s resistance and the voltage drop across it. Its adjustment can be done either externally using a trimming potentiometer or internally using a computer-controlled laser trimming system. Using this system, the CRB3A4E102GT can be programmed to handle resistances from 0.2 Ω to as high as 100 KΩ.

The CRB3A4E102GT has a low input power dissipation of only 2 mW and a wide temperature range of −55 to 175 °C, making it suitable for use in any environment where stability and accuracy are the primary considerations. Its low power dissipation also makes this device immune from the effects of EMI, reducing the amount of noise in the system.

Conclusion

CRB3A4E102GT is a versatile and highly reliable resistor network, which offers excellent performance and stability for both digital and analog applications. The device works on the principle of adjustable resistor ratios and is designed for use in applications requiring precise voltage drops. Its adjustable resistances, low power dissipation, and wide temperature range make it an ideal choice for use in power management systems, audio circuits, and data acquisition systems.
