YC124-JR-07220RL Resistors

Resistor networks and arrays are very useful components in electronic circuit design. They are typically used to provide more accurate current and voltage control than other components such as transistors and capacitors. The YC124-JR-07220RL is a type of resistor network that has specific characteristics suitable for certain applications. In this article, we will examine the application field and working principle of YC124-JR-07220RL.

Application Field of YC124-JR-07220RL

YC124-JR-07220RL resistor networks are typically used in power supplies, digital systems, medical equipment, and automotive applications. They are extremely reliable, being able to operate in temperatures up to 125°C. They can also be used for high frequency applications, as they ability to switch quickly and accurately from one resistance range to another. In addition, the package of YC124-JR-07220RL is very small, meaning it is well suited to modern, compact designs.

Working Principle of YC124-JR-07220RL

The YC124-JR-07220RL is a 4-terminal resistor network composed of three resistors, with each resistor having two adjustable resistance coils brazed onto it. The first coil, labeled A, is used to adjust resistance from 0 to 255 Ohms in states of 1 Ohm, 2 Ohms, or 4 Ohms per state, depending on the setting of the second coil, labeled B. The second coil is used to adjust the resistance from 0 to 255 Ohms with steps of 1 Ohm, 2 Ohms, 4 Ohms, or 8 Ohms, depending on the setting of the first coil. The two coils are connected in a series, meaning that when one coil is adjusted the other will follow, thus resulting in a single adjustable resistor network with maximum precision.

In order to adjust the resistance of the YC124-JR-07220RL, a voltage is applied across the adjustable rows. This voltage is then divided between the adjustable coils and a fixed resistor at the center of the network. The coil with the higher voltage will draw a larger current, and thus have a larger resistance. By adjusting the voltages of the two coils, the resistance of the YC124-JR-07220RL can be precisely adjusted.

Conclusion

The YC124-JR-07220RL is a versatile resistor network ideal for power supply, digital systems, medical equipment, and automotive applications. Its small size and ability to switch quickly from one resistance range to another make it ideal for modern, compact designs. By applying voltage across the adjustable rows, the resistance of the YC124-JR-07220RL can be precisely adjusted to meet the needs of its application.
