Through hole resistors are passive electronic components that have a specific resistance. They are usually used to divide operating voltages, limit the current flow, adjust signal levels and provide bias to active components. The LR1F732R is a through hole resistor design for high power applications.

The LR1F732R is a power film resistor with an axial leaded design. Its footprint is a diodes outline in a 7.32mm pitch with 3.2mm of rise, making it ideal for large applications needing a robust, reliable resistor.

The resistor has a rated power of 7.5Watts and the dissipation power is about 10Watts. It is capable of operating at temperatures up to 105 degrees Celsius. It is manufactured using a thick film approach in which a resistive element is printed in one direction and a nonconductive in the other.

The LR1F732R is a zero ohm resistor and has an internal resistance of less than 700mOhms. This makes it ideal for applications such as voltage conversion, current-limiting, power supply isolation, motor speed control and protection against faulty components.

The LR1F732R is a through hole resistor and its contact resistance is extremely low. This allows for a reliable signal flow and ensures the accuracy of the readings. The lead finish is tin/lead and this offers excellent corrosion resistance and solderability.

The LR1F732R’s working principle is based on the voltage applied to the resistor changing its resistance. This change in resistance causes a change in the current that is allowed to pass through it. This is an important factor when considering power, as higher voltages require more power to pass through the resistor. As such, high-power applications usually require larger resistors like the LR1F732R.

The LR1F732R is a through hole resistor designed for applications with high power requirements. Its low resistance and high current rating make it suitable for motor speed control, voltage conversion, power supply isolation, current limiting, and protection against short circuits. Its large size, robust construction, and corrosion resistant lead finish make it ideal for applications requiring reliable performance over a wide temperature range.
