Through Hole Resistors are electronic components that are designed to be installed on a printed circuit board through holes. The most common type of Through Hole Resistors is the LR2F91R. This type of resistor is commonly used in applications such as audio, video, data communication, telecommunications, and medical electronics. Its design allows for its use in a wide range of applications and ensures reliable and accurate performance. The LR2F91R has a non-inductive design which minimizes inductance and helps achieve wider voltage and power dissipation. The LR2F91R is designed to handle up to 1.4 watts of power at a working temperature range of -55°C to +150°C. It has an operating voltage range from 250V to 500V. The LR2F91R is composed of a resistor and two pieces of insulation. The resistive layer is made of carbon-based thick film resistors which is then coated with a protective epoxy layer. The insulation layer provides electrical insulation from the resistor to the printed circuit board. The insulator is composed of polyimide or nitrogen-doped silicon dioxide. The LR2F91R works by allowing current to pass through the resistive layer. The layer limits the current by providing resistance to the flow of electrons. As the resistance increases, the voltage drop increases and the current that can pass through decreases. The voltage drop is dependent upon the amount of resistance in the resistor. The working principle of the LR2F91R is very simple. When a current is applied to the resistor, the resistance will increase, decreasing the amount of current that can pass through the resistor. In addition, the voltage drop across the resistor will increase due to the increased resistance. This increase in voltage drop is what is used to calculate the amount of current passing through the resistor. The LR2F91R is ideal for a variety of applications including power supplies, amplifiers, transceivers, and line-level audio circuits. It is ideal for applications where high accuracy and high voltage regulation is required. The LR2F91R is also used in IC test systems, automotive, and test and measurement applications. Due to its compact size, the LR2F91R can be easily integrated into most printed boards. The LR2F91R is designed to provide accurate and reliable performance in any environment. Its non-inductive design helps reduce power losses, improves noise immunity and ensures accurate voltage and power regulation. In addition, the resistor can be used in a wide range of temperature environments and is designed to withstand extreme conditions. The LR2F91R is cost-effective and reliable, making it the perfect choice for many applications. It is a reliable and versatile electronic component that will ensure reliable performance and accurate voltage and power regulation.
