Trimmer Potentiometers

Trimmer potentiometers are most commonly used to adjust features of electronic circuits. This includes adjusting bias voltages, providing output offset adjustments, or adjusting the center frequency of a band-pass filter. Trimmer potentiometers offer an adjustable resistive element and are available in a range of sizes and values with two connection points.

Commonly used types of trimmer potentiometers include radial-lead, axial-lead and surface mount types. These types are designed to fit various applications, such as audio amplifiers and digital radio equipment for example.

PVA2A155A01R00 Application Field

The PVA2A155A01R00 is a precision top adjustment single-turn, surface-mount trimmer potentiometer with a resistance value of 15 kΩ. It can be used in virtually any type of electronic circuit, including home audio systems, automotive audio systems, or even in medical equipment. Some typical applications of the PVA2A155A01R00 are volume controls, filters and equalizers, as well as gain stages.

PVA2A155A01R00 Working Principle

In its simplest form, a trimmer potentiometer is composed of a resistive element and one or more contact points, the latter of which is adjustable. When one of the contact points is adjusted through mechanical means, the resistance value of the resistive element is changed as well. In the case of the PVA2A155A01R00, the contact point is adjusted with a top adjustment screw.

By adjusting the top adjustment screw on the PVA2A155A01R00 trimmer potentiometer, the point of contact between the contact points is moved, thus providing a variable resistance value of up to 15 kΩ. This in turn can be used to adjust the feature predetermined by the user.

Conclusion

Trimmer potentiometers are small, adjustable, and precise electronic components which are used to fine-tune the behaviours of electronic circuits. The PVA2A155A01R00 is a specific type of trimmer potentiometer with a top adjustment screw and a resistance value of 15 kΩ. Its versatile nature allows it to be used in a variety of applications, from home audio systems to medical equipment.
