PTD904-1015K-A102

Rotary Potentiometers and Rheostats are electronic components used to regulate and control electrical voltage and current in a circuit. The PTD904-1015K-A102 is a type of rotary potentiometer, which is a passive two-terminal component that is composed of a resistive element and a rotatable contact, or wiper. It is typically used as a voltage divider to obtain a manually adjustable voltage level.

The PTD904-1015K-A102 is a 3-terminal device, with two fixed pins and one wiper pin, which is movable over the resistive element by a rotary knob. It consists of a built-in resistor package controlled by a wiper which is manually adjusted to set the resistance of the package. It operates at a voltage rating of up to 10 Volts DC and can handle up to 1.5 Amps at 85°C. The PTD904-1015K-A102 has a resistance range of 10K ohm and a tolerance rating of 10%.

The primary application of the PTD904-1015K-A102 rotary potentiometer is to provide a variable resistance in a circuit. It provides a way to accurately adjust the output voltage of a circuit. This can be used to control the voltage levels in a system, such as in amplifiers, receivers, and digital-to-analog converters. The adjustable output level of the device also allows it to be used to regulate motor speed and lighting levels.

In addition to its application as a voltage divider, the PTD904-1015K-A102 also has a number of other uses. It can be used as a volume control for audio systems, as a potentiometer for motor speed control, and as a rheostat to control the current in a circuit. In these applications, the wiper is adjusted to regulate the amount of current flowing through the circuit.

The working principle of the PTD904-1015K-A102 is quite simple. The limit of the adjustable range of the resistance is set by the two fixed pins of the device. As the wiper is rotated, it physically moves along the resistive element, increasing or decreasing the resistance in the circuit accordingly. By controlling the position of the wiper, the resistance can be adjusted, thus allowing the user to regulate the current of the circuit.

The PTD904-1015K-A102 is a versatile and reliable rotary potentiometer, with many applications in audio, motor speed control, and voltage regulation. Its simple working principle makes it easy to use and it is highly durable, making it a great choice for many electronics projects.
