Through Hole Resistors

RN65D3481FBSL Application Field and Working Principle

Through hole resistors, ranging from low power to high power, are widely used in a variety of applications. The RN65D3481FBSL, a typical through hole resistor, is a vitreous enamel coated 5W resistor which is suitable for use in applications such as telecoms, motors, instruments, power supplies and more.

The Construction of RN65D3481FBSL

The RN65D3481FBSL resistor is composed of two parts: a ceramic core and a metal lead. The core is made of a ceramic-based material filled with carbon or metallic powder coat. This powder coating creates a stable and uniform resistive path for electrical current passing through it. The metal lead is made of a non-magnetic material, such as copper, which reduces the eddy current effect caused by the high current passing through the resistor. This combination of core materials and lead materials makes the RN65D3481FBSL resistor highly suitable for use in high frequency and high power applications.

Application Fields of RN65D3481FBSL

Due to its low temperature coefficient, the RN65D3481FBSL is well suited for applications which require high accuracy and stability. The low temperature coefficient (0.02%) provides excellent temperature compensation and temperature stability when operating over wide temperature ranges. Furthermore, the RN65D3481FBSL is rated at 5W and can withstand high power loads. This makes it suitable for use in applications such as telecoms, motors, instruments, power supplies and more.

Working Principle of RN65D3481FBSL

The working principle of a through hole resistor is the same as that of any other resistor. It functions as a voltage divider, dividing the applied voltage across its terminals according to its resistive value. The terminals of a through hole resistor are designed to be able to withstand high power, and thus are insulated with a vitreous enamel coating. This protects the metal lead from heat dissipation and oxidation which may occur during its operation. When a voltage is applied to the terminals, the ceramic core and the surrounding metal lead resist the flow of current according to the resistance value of the resistor. The current through the resistor is proportional to the voltage applied across the terminals, known as Ohm\'s Law. The Ohm\'s Law states that the voltage across the terminals is proportional to the current passing through the resistor, as expressed in this formula: V = I*R, where V is the voltage, I is the current and R is the resistance of the resistor.

Conclusion

The RN65D3481FBSL is a 5W through hole resistor which is suitable for use in applications such as telecoms, motors, instruments, power supplies and more. Its low temperature coefficient (0.02%), combined with its high power rating, makes it an ideal choice for many applications. Furthermore, the principle of operation of the RN65D3481FBSL is the same as for any other resistor, using Ohm\'s Law to determine the voltage across its terminals according to the current passing through it.
