E300K12R

Adjustable power resistors are commonly used components in modern electronic circuits. The E300K12R type of adjustable power resistor is a potential divider with two terminals joined by a resistor element. Its resistance can be adjusted or varied using a screw-adjustment mechanism. Depending on the desired output, the resistor depth setting can be adjusted, resulting in different resistances and voltages.

The E300K12R adjustable power resistor is a precision resistor with a high power rating and features a 12-turn, micrometer adjustment knob. It is commonly used in applications such as voltage and current regulation, impedance matching, and noise suppression. It is also used in power supplies, audio equipment, broadcast equipment, and high-end audio systems.

The working principle of the E300K12R adjustable power resistor is simple. By moving the adjustment knob, the amount of current passing through the resistor is adjusted. When adjusted, the resistance of the resistor varies and the voltage is equally divided between the two resistors. The resistance value can be read off from the markings on the resistor body.

The voltage rating of the E300K12R adjustable power resistor is up to 300V and it can handle moderate power of up to 2W. The resistance range of the resistor is between 0.1 ohms and 300K ohms. It is a non-inductive and flame-resistant resistor with short-term overload and spark-over voltage protections. The resistor also features an insulating link to protect the potentiometer from being overloaded or sparking.

The E300K12R adjustable power resistor is widely used in applications such as voltage and current monitoring, noise suppression, impedance matching, and waveform modulation. Its use in power supplies, broadcasting equipment, audio equipment, and other applications helps to control the desired amount of current in the circuit. Due to its adjustable knob, the resistor can be connected to various circuit connections to produce different voltage or current values as required.

To sum up, the E300K12R adjustable power resistor is a precision resistor with a high power rating and features a 12-turn, micrometer adjustment knob. Its use allows for easy and precise voltage and current regulation, impedance matching, and noise suppression. The power resistor is also known for its flame proof-property and overload and spark-over voltage protection. The resistor is widely used in various applications, allowing for flexible control of the desired amount of current in the circuit.
