Trimmer Potentiometers

Trimmer potentiometers are variable resistors that adjust and fine-tune circuits to optimize the performance of applications. There is no one-size-fits-all trimmer potentiometer, with various packages and configurations available depending on the specific application. For example, 84PR10KLFTR Trimmer Potentiometers are specifically designed for applications where space is at a premium.

84PR10KLFTR Application Field

The 84PR10KLFTR Trimmer Potentiometer is designed for compact and space-constrained applications, where its 9.3mm diameter makes it ideal for mounting on surface-mounting equipment or in tight spaces. It is most commonly used in portable consumer and industrial electronics, and is well-suited for device-level trimming and tuning applications such as phase-locked loops, temperature control circuits, and motor drive systems.

84PR10KLFTR Working Principle

The 84PR10KLFTR Trimmer Potentiometer is a resistive element that functions through the application of electrical current. It is typically constructed from a conductive metal layer such as aluminum, copper, or brass, which is sandwiched between two nearly-coincident, dielectric layers. Its resistive element is connected between two terminals, and a third terminal is connected to the wiper. As current is applied to the circuit, the wiper rotates, allowing a varying degree of electrical resistance to any given voltage. The resistance provided by the trimmer potentiometer is determined by the position of the wiper relative to the two terminals, resulting in different resistance values at each rotational position along the circumference of the element.

Conclusion

The 84PR10KLFTR Trimmer Potentiometer is an ideal choice for space-constrained applications due to its compact 9.3mm diameter. It is commonly used for device-level trimming and tuning applications, where its resistive element functions through the application of electrical currents. Its three terminals connect to the two fixed points and the adjustable wiper, which can be rotated to vary the electrical resistance and tune the application accordingly.
