Resistor Networks, Arrays are electronic components typically made up of two or more individual resistors connected together in a combined system. The term “resistor network” typically refers to networks of standard, discrete resistors; while the term “array” usually refers to systems of resistors that are integrated into a single device. This article will discuss the TC164-FR-07475RL series application field and working principle.

TC164-FR-07475RL is a surface mountable network of resistors consisting of four resistors arranged in a single, rectangular package. The four resistors are connected in parallel, forming a single resistor network. Each resistor in the network is stamped with appropriate resistor values, and each resistor in the network is electrically isolated from the other resistors. This particular network is made using a combination of thick and thin film resistor technologies. Each resistor is a three or four terminal device, having two terminals connected to the resistor element and one or two terminals connected to the substrate.

The TC164-FR-07475RL series has a wide range of applications due to its versatility and relatively small package size. It is used in surface mount resistor networks, current limiting applications, high power resistor networks, as well as low temperature coefficient (RTC) applications. The series can also be used in high frequency operations due to its low parasitic capacitance. This series is particularly well suited for low-voltage applications, due to its low on-resistance and low voltage coefficient (VCO).

The TC164-FR-07475RL series is capable of withstanding a wide operating temperature range from -40°C to +125°C. This means that it can be used in extreme environments, including military, medical, and automotive applications. The series also boasts a low thermal resistance, ensuring efficient heat dissipation from the resistors. The maximum power rating for this network series is 40 watts when under natural air cooling. When used with forced air cooling, the maximum power rating for the series is increased to 60 watts.

The TC164-FR-07475RL series is commonly used in power control, temperature sensing, temperature compensation, current limiting, and impedance matching applications. When used in power control applications, the series can be used in switching power supplies, to regulate the output voltage and current. In temperature sensing applications, the series is used to measure temperature by sensing the voltage drop across the resistor. In temperature compensation applications, the series is used to offset the effects of temperature on a circuit’s performance. In current limiting applications, the series is used to limit the current through a circuit. In impedance matching applications, the series is used to "match" the impedance of a circuit to a certain value.

The working principle of the TC164-FR-07475RL series is based on the fact that each resistor in the network has a specific value of resistance that is stamped on it. The voltage applied to the network is divided by the resistance of each resistor, depending on the desired outcome. The current that flows through the network is determined by the total resistance of the network. As the current increases, the voltage drops across each resistor in the network. When used in a power control application, the series is used to regulate the output voltage and current through the use of a feedback loop. The series is also used to regulate the temperature in a circuit by sensing the voltage drop across the resistor.

In conclusion, the TC164-FR-07475RL series is a versatile and reliable network resistor designed to operate in a wide range of environments and applications. The series has low parasitic capacitance and low thermal resistance, allowing for efficient heat dissipation from the resistors. The series is also capable of withstanding extreme temperatures and power ratings. The series is commonly used in power control, temperature sensing, temperature compensation, current limiting, and impedance matching applications. By understanding the working principle of the network resistor series, engineers and technicians can take full advantage of its capabilities and find the best solution for their application.
