Through Hole Resistors are electronic components used in a wide range of electrical circuits for the purpose of providing electrical resistance in order to limit current. These resistors generally have a physical size and shape dependent on the wattage, which is the amount of electrical energy the resistor can manage. Among them, a popular Through Hole resistor is the LR2F470R.

The LR2F470R is a 4.7Ω direct-lead-terminated resistor that is available in both quarter (2 watt) and half (4 watt) wattage sizes. It is manufactured using a thick metal oxide resistance element in a flame-resistant composition that is encased in a molded non-polymeric body. The resistor is robust enough to handle both thermal and overload stress, and it is designed to be used in high-volume circuit applications.

Greater accuracy and stability are provided by the LR2F470R through the use of precision-molded resistors with wattages that range from 2W to 4W. This resistor also has a precision tolerance of ± 5%. This means that the value of the resistance is always within 5% of the marked value of the resistor. The LR2F470R also comes with a temperature coefficient of ± 10 ppm/°C, ensuring that the resistance value stays steady over a wide range of temperatures, making it ideal for temperature-sensitive circuits.

The LR2F470R resistor has a wide range of applications, including circuits that require high power, current limiting, inrush current limiting, surge current limiting, and voltage-limiting. It can also be used in safety circuits, where the fail-safe resistor ensures that the circuit automatically shuts down if the voltage exceeds safe limits.The LR2F470R resistor is also commonly used in high-frequency circuits, such as radio-frequency or microwave-frequency circuits, as its lead termination helps prevent signal interference.In terms of its working principle, the LR2F470R resistor functions by limiting the current that flows through the circuit by offering resistance to the current. When the current flows through the resistor, it encounters opposition and the energy is dissipated as heat. Depending on the wattage of the resistor, it may handle higher currents before it reaches its thermal limit. In some cases, the resistor may be bypassed or placed in parallel with another resistor in order to increase the operational range and decrease losses.

The LR2F470R resistor is an ideal electronic component for a variety of applications that require a robust, reliable, and accurate component. Its flame-resistant composition ensures safety, and its precision-molding and temperature coefficient ensures accuracy and stability over a wide range of temperatures. The wide range of applications for the LR2F470R resistor make it an attractive choice for circuit designers.
