Through Hole Resistors are widely used in various applications due to their reliable performances and wide range of operation. The LR2F510R Through Hole Resistor is no exception. It is a general-purpose, fixed resistor with superior performance and reliability due to its wire-cored construction.

An LR2F510R Through Hole Resistor features a long cylindrical metal tube with a closed end and a free end. It can be either soldered or welded onto a circuit board. The resistor value is coded at the free end, and the bottom end is fitted with a spring clip to secure the resistor from vibration. The long cylindrical body of the LR2F510R contains an insulated wirewound resistance element surrounded by layers of insulation material. It is then filled with an inert gas such as nitrogen or argon, and sealed with sliding metal caps. Due to its construction, the LR2F510R is highly resistant to moisture, shock and vibration. It provides excellent insulation characteristics and is suitable for applications where high protection from electrostatic discharge is required.

The LR2F510R Through Hole Resistor is used mainly for sensing current and voltage in high-power applications. It is also suitable for pulse and switching applications, RF and microwave circuits and industrial control. Due to its construction, the LR2F510R offers extremely good thermal stability and low temperature coefficient. It is an ideal choice for applications that require high power or precise current and voltage sensing, such as motor control, power supplies and HVAC systems.

The working principle of the LR2F510R Through Hole Resistor is simple. When a current passes through the resistor, it experiences a voltage drop across its terminals due to the resistance of the wirewound element. The resistance value is determined by the length of the wire and the material used. Furthermore, the resistor dissipates the electrical energy as heat, and the energy dissipation can be calculated based on Ohm’s law.

In conclusion, the LR2F510R Through Hole Resistor is an excellent choice for a wide variety of applications. With its durable and reliable construction, it provides excellent thermal stability and long-term performance. Furthermore, its wide range of applications makes it ideal for use in motor control, power supplies, RF circuits and other high-power and high-precision sensing applications.
