Resistor Networks, Arrays are widely used in many electronic circuits. The 4820P-T01-471LF is one of the most common resistor networks used in such circuits. It is available in the 0402 package, the smallest package size available on the market. This article will discuss the application field and working principle of the 4820P-T01-471LF.

The 4820P-T01-471LF is a four-terminal thin-film network containing four resistors in parallel. Its value is 471 ohms ±2%, and its elements are precision thick-film chip resistors to ensure high reliability. The parallel design helps reduce the errors caused by parasitic resistances. The 4820P-T01-471LF also features voltage co-planarity and low thermal EMF. It is ideal for use in current-sensing circuits, feedback circuits, protection windings, and other applications requiring precision resistors.

The working principle of the 4820P-T01-471LF consists of three parts: resistance, capacitance, and inductance. The resistance of the four resistors in the 4820P-T01-471LF is 471 ohms. The capacitance value between the four resistors is determined by the physical structure of the 4820P-T01-471LF package. The inductance of each embedded resistor is low, further contributing to the device’s low parasitic resistance.

The 4820P-T01-471LF applies in current sensing circuits, test instruments, etc. In current sensing circuits, it is used to measure the voltage drop across a resistive shunt. This voltage is proportional to the current in the shunt, and can be used to measure the current in the circuit. In test instruments, the 4820P-T01-471LF is used to create a voltage divider. By applying a known voltage to a resistive divider circuit, the output voltage at each end of the network can be determined.

The 4820P-T01-471LF is also widely used in protection windings. These windings act as a fault-protection device. When the current in the winding reaches a certain level, a special relay opens the circuit, thus protecting the connected device or components. By using the 4820P-T01-471LF, the fault protection voltage can be precisely set.

In feedback circuits, the 4820P-T01-471LF is used to create a voltage divider. The output voltage of the circuit will be proportional to the input voltage. This can be used to control the output of the circuit, by varying the input voltage.

In summary, the 4820P-T01-471LF is a four-terminal thin-film network containing four resistors in parallel. Its value is 471 ohms ±2%, and its elements are precision thick-film chip resistors. The 4820P-T01-471LF is used in current sensing circuits, test instruments, protection windings, and feedback circuits. Its resistance, capacitance, and inductance values provide it with high reliability.
