Through Hole Resistors are used to provide electrical resistance in an electrical circuit and to control the amount of current in a circuit. The FCR2WSJT-52-390R is one type of through-hole resistor. It is a common resistor with a wide range of uses in electrical circuits.

The FCR2WSJT-52-390R has a resistance value of 390 ohms with a power rating of 2W. The temperature coefficient is 1/2W/K and it has a working temperature range of -55°C to +125°C. This part is also marked as “CCR” which means Constant Current Resistor.

This through-hole resistor can be used in a variety of applications. It is suitable for switching power supply, inverter power supply, or low voltage LED light circuit in which a constant current is needed. It is also ideal for controlling the current in a relay circuit or an AC motor circuit. In addition, this resistor can also be used in the electronic volume control circuit to keep the attenuation of the sound signal within an acceptable range.

The FCR2WSJT-52-390R works on the principle of electrical resistance. The resistor has two terminals and when an electric current passes through it, the electrons encounter a resistance which reduces the electric current. The amount of current that flows through the resistor depends on the resistance value of the material in the resistor. This resistor is a 390 ohm resistor which creates a resistance of 390 ohms for the amount of current passing through it.

The power rating of the FCR2WSJT-52-390R indicates the maximum amount of power it can handle. Its power rating of 2 watts means that the resistor can handle 2 watts of power, otherwise it can overheat and be damaged. It also has a temperature coefficient which indicates the amount of change in its resistance due to an increase in temperature. The temperature coefficient of 1/2W/K indicates that the resistance of the resistor can change by up to 1/2 watt for every degree increase in temperature.

The FCR2WSJT-52-390R is a reliable and versatile through-hole resistor that can be used in many different applications. It has a resistance value of 390 ohms, a power rating of 2 watts and a temperature coefficient of 1/2 W/K. It can be used in power supply, relay, LED light circuit, AC motor circuit, and electronic volume control circuit. It works based on the principle of electrical resistance, reducing the amount of current in the circuit.
