Through Hole Resistors

Through hole resistors are a type of passive component found in most electronic circuits. The FCR200JR-73-3K9 is an example of such component. They are used to limit current to a safe level as well as provide impedance to a circuit. The FCR200JR-73-3K9 is a through hole resistor that measures 3 kilo-ohms at 73% tolerance.

Application Field

The FCR200JR-73-3K9 is a common type of through hole resistor. Its primary application is to limit current or voltage in a circuit, with its most common form being an adjustable miniature through-hole potentiometer. The FCR200JR-73-3K9 is often used in audio and video electronics, such as amplifiers, receivers, and cassette players. In addition, it is used in automobile applications, including anti-lock brakes, power steering, and power windows. The resistor can also be used in medical devices, such as sportman\'s heart monitors, as well as in other consumer electronics, like video game consoles.

Working Principle

Through hole resistors work on the principle of Ohm’s law to limit current and provide impedance. According to Ohm’s law, resistance is equal to the voltage (V) divided by current (I). This means that the FCR200JR-73-3K9’s resistance of 3 kilo-ohms can be used to limit the current to a safe level, and provide impedance to the circuit.This is achieved by connecting the resistor in series with the circuit. The resistor will reduce the overall current flow, while also providing voltage drop across its terminals. If the application requires increased resistance, the resistor can be connected in parallel with the circuit.

Through hole resistors are a well-established component for electronics purposes, and the FCR200JR-73-3K9 is an example of such a component. It is suited for audio and video electronics, automotive applications, medical devices, and other consumer electronics. Its resistance is used in accordance with Ohm’s law to limit current and provide impedance to the circuit.
