Resistor Networks, Arrays

The Y4485V0004BT9L resistor is a type of network resistor array. A network resistor array is a type of resistor where multiple resistors are connected together to form a single circuit. This type of resistor is beneficial in providing more reliability and accuracy than would be obtainable using a single resistor of the same value. It is also more reliable for applications where multiple resistors are required.

The specific Y4485V0004BT9L resistor consists of four metal oxide film resistors connected in parallel. Each resistor is rated at 1 watt and is rated at 4.7k ohms. This particular array is designed to provide 0.25% tolerance and has a temperature coefficient of 25ppm/°C. These values are important in determining the accuracy and reliability of the resistor array.

The main application of the Y4485V0004BT9L resistor is for impedance matching or noise suppression. The parallel arrangement of the four resistors offers a small resistance that can be used to match the impedance of two circuits. This enables the power transfer to take place with minimal reflection, reducing the amount of noise present on the signal being transferred. The resistor array can also be used for current limiting, frequency division, signal mixing and voltage division, depending on the application.

The working principle of the Y4485V0004BT9L resistor is simple. When voltage is applied to the leads on either side of the resistor array, the voltage is converted into current. This current then flows through the four resistors in the array, distributed evenly throughout. As current passes through the resistors, it is held back by the resistance of the material, preventing it from traveling further.

The resistance of the resistors determines the flow of current and the amount of time that current takes to be regulated. A higher resistance results in slower current movement, while a lower resistance results in faster current regulation. The temperature coefficient of the resistors can also affect the flow of current, as a lower temperature coefficient will cause the resistance to decrease as the temperature increases.

The Y4485V0004BT9L resistor array is a reliable and accurate component for a variety of applications. Its parallel resistor arrangement provides a low resistance for impedance matching and noise suppression, as well as numerous other applications. The working principle of the resistor array is based on current conversion and resistance control, enabling accurate regulation of the current.
