4818P-T02-472 Application Field and Working Principle

4818P-T02-472 is a specialty resistor product line designed and manufactured by Sii\'s Resistor. It is made up of a 4.72 ohm chip resistor along with a collection of other resistors which are used in industry as an electrical component and is used in applications such as burn-in, automotive and power-supply. In addition to providing reliable performance in these applications, this product line also offers significant advantages in cost savings.

Working Principle of Sii\'s 4818P-T02-472 Resistor Network

In a typical resistor network, individual resistors work together as a group to reduce the overall resistance in a circuit. Sii\'s 4818P-T02-472 series resistor network takes this concept one step further by combining various resistors in order to create a higher level of resistance. This is accomplished by connecting a higher valued resistor with a lower valued resistor in an arrangement that reduces the overall resistance. This type of network is also known as an "equalization network" or "graded resistance network" because of its ability to achieve a higher level of resistance by combining various individual resistors.

Applications for Sii\'s 4818P-T02-472 Resistor Network

Sii\'s 4818P-T02-472 series resistor network is used in a variety of electrical applications, including:

• Power supplies
• Burn-in testing
• Automotive circuits

In power supplies, the Sii\'s 4818P-T02-472 series resistor network can be used to create a current limiting circuit that protects sensitive electronic components from over-voltage or over-current conditions. In burn-in testing, the equalized resistance can be used to reduce the power dissipation of the network, thus decreasing the risk of thermal damage to the test components. Automotive circuits often employ the resistors of the 4818P-T02-472 series to control electrical load and ensure the proper operation of vehicle subsystems.

Design Considerations for Sii\'s 4818P-T02-472 Resistor Network

When designing a Sii\'s 4818P-T02-472 series resistor network, there are several important considerations. One of the most important factors is total power dissipation. It is important to ensure that the total power dissipated by the network does not exceed the maximum allowable rating of the resistors in the network. Additionally, the individual resistor values should be chosen to ensure that each resistor is operating within its specified power dissipation rating. It is also important to ensure that the total resistance of the network is appropriate for the circuit in which it is being used.

When selecting the individual resistor values, it is also important to consider the effect of the temperature coefficient. The temperature coefficient is a metric used to describe how the total resistance of a resistor will change as the temperature changes. It is important to select resistors with the appropriate temperature coefficient in order to ensure that the total resistance of the network remains constant over a wide range of temperatures.

Lastly, it is also important to consider the effect of part tolerance when selecting the individual resistors. The tolerance of a resistor is a metric used to describe the range of resistance that will be present when the resistor is measured. It is important to select resistors that have a tolerance that is appropriate for the application in order to ensure proper functioning of the circuit.

Conclusion

Sii\'s 4818P-T02-472 series resistor network is an ideal solution for reducing the overall resistance in a circuit. With its wide range of applications, this network offers significant advantages in cost savings, power dissipation, and temperature stability. When designing a circuit using this network, there are several important considerations, such as power dissipation, temperature coefficient, and part tolerance. By taking these factors into account, the designer can ensure that the circuit functions properly and with optimal performance.
