Application

The LR1F4K7 is used in a variety of applications including power supplies, amplifiers, and signal conditioning. Its low resistance range makes it especially useful for large scale industrial applications such as controlling the speed of a motor or regulating the output of a power supply. The resistor is also suitable for any situation which requires accurate current control and voltage regulation.

Design

The LR1F4K7 features a 4.7kΩ resistance range and is rated for a working voltage up to 250 volts. The resistor is designed to be mounted on a printed circuit board (PCB) or other type of through hole mount. It features a radial lead design which ensures that the resistor is securely connected to the PCB. The resistor also features a temperature coefficient of approximately 200 ppm/°C.

Working Principle

The LR1F4K7 works on the basic principle of electrical resistance in relation to voltage. Whenever a voltage is applied across the resistor it creates a current which passes through the resistor. The resistor reduces the current and the amount of resistance determines the amount of the current that is allowed to pass through the resistor. The resistance of the LR1F4K7 is used to regulate the flow of the current and regulate the output voltage across the circuit.
