Resistor Networks, Arrays generally refer to the combination or arrangement of resistors incorporated into a circuit to perform certain functions, such as control and equalization of current flow or voltage sharing. YC102-JR-071K3L is a common type resistor network/ array, composed of three resistors in the form of 10 Ohm, 20 Ohm, 30 Ohm integrated in one package. It is typically used for current sensing and voltage divider circuits.

The following introduction is about YC102-JR-071K3L application field and working principle.

Application fields of YC102-JR-071K3L

YC102-JR-071K3L is a 10-20-30 three-resister array mainly used for precision voltage divider and current sensing applications. It is widely applied in industrial automation, automotive, medical, communication, consumer, aerospace and defense fields. The typical applications are :

• Automotive sensing circuits (current sensing, low voltage voltage sensing, etc.)
• Electronic programming and control
• Industrial automation
• Communications
• Computer networks
• Aerospace and Defense (precision current sensing)

Working Principle of YC102-JR-071K3L

The YC102-JR-071K3L resistor array consists of three resistors in the form of 10 Ohm, 20 Ohm, 30 Ohm. These resistors are connected in series to form a voltage divider circuit. When a current is passed through this voltage divider, each resistor will draw a portion of the voltage based on its resistance value. For the YC102-JR-071K3L, the voltage is divided 10:20:30 (10:2:3), meaning 10V is divided among the three resistors, with 10V being applied across the 10 Ohm resistor, 20V across the 20 Ohm resistor and 30V across the 30 Ohm resistor.

In addition to forming voltage divider circuits, YC102-JR-071K3L can also be used to measure current. By connecting the resistors in parallel, instead of series, it acts as a current sense/shunt resistor. When current flows through this resistor array, the voltage drop across each resistor is proportional to its resistance value, so the 10V drop across the 10 Ohm resistor represents 1A of current, the 20V drop across the 20 Ohm resistor represents 2A of current, and the 30V drop across the 30 Ohm resistor represents 3A of current.

Advantages of YC102-JR-071K3L

The YC102-JR-071K3L has several advantages over conventional discrete resistors. Firstly, by combining three resistors in one package, it significantly reduces the space occupation and manufacturing cost. Secondly, due to its precision, the resulting current or voltage division is more accurate than using a single resistor. Thirdly, it provides higher power dissipation than discrete resistors. By reducing power dissipation, it can help reduce the temperature of the circuit and ensure that components remain within their operating temperature range.

Conclusion

The YC102-JR-071K3L three-resister array is commonly used for precision voltage divider and current sensing applications. It offers multiple advantages over discrete resistors, such as lower cost, higher accuracy, and better power dissipation. Its applications are diverse, ranging from automotive electronics and industrial automation to aerospace and defense fields.
