Trimmer Potentiometers

Trimmer Potentiometers are electrical components-variable resistors-that can be adjusted to set the desired current or voltage in a circuit. Potentiometers use a rotating or sliding contact—known as a wiper—to adjust the resistance. They are usually found in the form of a knob, dial, or slider.

The 3009Y-1-504LF Trimmer Potentiometer is a type of adjustable resistor made by Keystone Components. It has a resistance range of 1K ohms to 10K ohms, with an operating temperature range of -55° to 105°C. The 3009Y-1-504LF has a power rating of 0.5 watts, and a tolerance of ±20%.

Application Field and Working Principle of the 3009Y-1-504LF

The 3009Y-1-504LF Trimmer Potentiometer can be used for a variety of applications. It can be used to control the speed of a motor, as a dimmer switch to adjust the brightness of a light, or as a variable resistor in audio circuits. It can also be used to adjust the gain of an amplifier or to adjust the voltage in a power supply.

The 3009Y-1-504LF is an adjustable resistor that operates on the principle of a three-terminal potentiometer. The three terminals are called the tap, wiper, and common. The tap and common terminals are connected to the ends of a resistive element, while the wiper is connected to the variable tap. When the wiper is moved, it adjusts the resistance between the tap and the common terminal, thereby controlling the current in the circuit.

The 3009Y-1-504LF has a special feature that allows the resistance to be adjusted without powering the resistor. This is done by removing the top cover and adjusting the wiper with a small screwdriver. This makes the 3009Y-1-504LF ideal for applications that require an adjustable resistor while there is no power in the circuit, such as for testing or prototype circuits.

The 3009Y-1-504LF comes in a standard axial-leaded package. The body is made of polymer resin and is RoHS compliant. The mounting tabs are designed to ensure an easy and secure installation. The 3009Y-1-504LF is rated at 0.5 watts and is UL recognized.

The 3009Y-1-504LF Trimmer Potentiometer is a versatile and reliable component that can be used in a variety of electronic circuits. The adjustable resistance and the ability to be adjusted without powering the component make it an excellent choice for many applications.
