Trimmer resistor for precise voltage setting

Trimmer resistors - also known as trimmer potentiometers - are mechanically adjustable components that play a decisive role in the fine adjustment of voltage or current values in electronic circuits. They enable precise calibration of systems and are usually set once during commissioning or maintenance to ensure maximum accuracy.

Bourns Trimpot Trimmer for professional audio electronics

Trimmers are electromechanical components with three connections that act as adjustable resistors. They consist of a resistor element and a mechanically movable wiper, which is finely adjusted by turning. Depending on the design - single-turn or multi-turn - the adjustment is made either via a simple rotary movement or via a multi-speed gearbox for particularly fine adjustments.

In this section, we have compiled the most important questions about EMC and shielding solutions for you. Here you will find useful information on the basics, the areas of application and the benefits of our products

What are trimmers and what are they used for?

Trimmers are electromechanical components that are used as adjustable resistors in electronic circuits. They are used for the precise adjustment and calibration of electrical parameters such as voltage, current or frequency. Trimmers are often used for one-off fine adjustment in laboratory equipmen...

How do trimmers differ from potentiometers or other variable resistors?

Trimmers differ from classic potentiometers primarily in terms of their intended use and their mechanical design. While Potentiometer are usually intended for regular manual adjustments, trimmers are primarily used for one-off or infrequent adjustments within electronic devices. Trimmers offer fine...

What types of trimmer are there and how are they selected?

Trimmers are available in various designs, including single-turn and multi-turn models as well as open or sealed designs. The selection of a suitable trimmer depends heavily on the area of application and the requirements for accuracy, stability and available space. Multi-turn trimmers enable parti...

Where are trimmers used when maximum precision and stability are required?

Trimmer kommen immer dann zum Einsatz, wenn eine exakte Justierung elektronischer Parameter erforderlich ist – insbesondere in kritischen Anwendungen mit hohen Anforderungen an Stabilität und Zuverlässigkeit. Dazu zählen Präzisionsmessgeräte, Laborgeräte, Audioverstärker, Sensoranwendungen sowie mi...

What should be considered when processing and placing trimmers on PCBs?

When fitting trimmers on PCBs, careful planning is crucial for functionality and service life. Trimmers should be positioned in such a way that they are easily accessible during commissioning or maintenance. A mechanically stable solder connection is important to avoid deformation or contact proble...
