Slide Potentiometers, or sliding resistors as they are sometimes called, are compact, low-cost devices that are typically used for single-axis control of electrical signals. The PS45G-B3SBR100K is a slide potentiometer specifically designed for signal-control applications. It is constructed with a field-effect transistor (FET) that has a static electrical charge of approximately 250 millivolts for a low-voltage dropout. In operation, the user slides the FET along the track to adjust the signal strength.

The PS45G-B3SBR100K has a frequency response of up to 1000 Mhz and an input impedance of approximately 330kΩ, which enables it to accurately transmit or adjust signals at high frequency without significant loss of signal quality. Its operating temperature is 0°C to +60°C, enabling it to be used in a variety of environmental conditions. The potentiometer also has a linear taper voltage: at 0 ohm, the voltage is 0V and at 30kohm, the voltage is 3V. This makes it well-suited for applications where a linear voltage drop is necessary.

The PS45G-B3SBR100K slide potentiometer is ideal for a range of applications, from basic audio and video applications to complex signal-routing tasks. It is also often used in medical instrumentation, where precise signal control is required. In audio/video applications, it can be used to control sound volume or contrast/brightness levels. It can also be used to regulate levels of signals sent from amplifiers to speakers and monitors.

The working principle of slide potentiometers is quite simple. A common application is that of a potentiometer connected at two ends to a voltage, usually a battery. When a user moves the sliding contact across the surface, they are actually adjusting the resistance. This changes the current flow in the potentiometer and in turn, affects the electrical signal that is the transmission is made across the cell connections.

In the case of the PS45G-B3SBR100K, the sliding contact is connected to a FET, which is what allows for the current to flow through. When the contact is moved, the FET voltage is changed and the signal, in turn, is adjusted. The device is designed so that the current is kept constant throughout the voltage range, ensuring reliable performance and a steady signal output.

Slide potentiometers are widely used for applications that require control over electrical signals. The PS45G-B3SBR100K is a particularly useful device, offering a frequency response of up to 1000 Mhz and a linear taper voltage that makes it well-suited for a range of signal control tasks. From basic audio and video applications to complex signal-routing tasks, the PS45G-B3SBR100K is an ideal choice.
