Through-Hole Resistors are widely used in electronic circuits to control current flow. They serve a variety of purposes, from power supply regulation and motor speed control to signal amplitude and waveform regulation. The RN55D3652FRSL application field and working principle is just one example of this type of component.

RN55D3652FRSL Working Principle

The RN55D3652FRSL is a through-hole resistor, used for current limiting, voltage division, and power dissipation. It’s made up of a scaled-down version of the same ceramic material used in surface mount resistors. This gives it a low inductance, allowing for a more precise temperature coefficient. Both the resistance and power dissipation are also higher than what’s available for SMD components.

The resistor is designed to have a resistance of between 3.6 and 5.5 ohms, with an allowed tolerance of 5%. It’s current rating is 35 amps maximum, with a power rating of 3 watts maximum. The resistor also has a low thermal rise compared to other resistors, allowing it to dissipate heat quickly and dissipate heat more consistently than other resistors.

RN55D3652FRSL Application Field

The RN55D3652FRSL is mainly used in circuit designs which require a low resistance and power rating. Primarily, these include low voltage and short duration electronic circuits, where a high tolerance for temperature is desired. It’s also commonly used for frequency range and pulse circuit applications.

The resistor can be used in battery-powered circuits as well, due to its high efficiency. This makes it a great choice for controlling or regulating power in battery-powered devices. The low thermal rise also prevents circuit damage due to overheating, ensuring that the circuit can stay functional for much longer.

Of course, the resistor is also very useful in light-load circuits. This can be used to reduce current load and prevent potential circuit damage. Additionally, its small size makes it a great choice for SMD mounting, allowing it to be placed in tight spots where other components cannot fit.

Conclusion

Through-Hole Resistors serve a wide variety of purposes in electronic circuits. The RN55D3652FRSL is a great example of this type of component, offering a low resistance with a high power rating. This makes it ideal for low-power and low thermal rise circuits, allowing for efficient power control over longer periods. By understanding its working principle and application field, electrical engineers can make the best use of this component.
