Multiturn Trimpot® Trimming Potentiometers

Trimpot® Trimming Potentiometers - Multiturn

Bourns® Trimpot® Trimming potentiometers perform a variety of circuit adjustments in all types of electronic equipment. The variety of physical configurations available and the ability to withstand today's manufacturing environment offers the designer flexibility in selecting the best trimmer for the application.

Bourns Multi-turn trimmers consist of three actuation types - lead screw, worm gear, and planetary gear. Lead screw actuated trimmers have a linear wiper path; worm gear and planetary gear actuated trimmers have a circular path. Multiturn trimmers are suitable for applications that require fine resistance adjustment. Package types are sealed to withstand standard cleaning processes.

Multi-turn trimmers allow for fine-tuning and provide a faster setting-to-time ratio than single-turn trimmers.

Customers choose Bourns for our 70-year history of trimming potentiometer technology innovation and broad range of physical configurations; rugged enough to withstand today's manufacturing environments. Around the world, Bourns Trimpot products are used in virtually every electronic market.

*CRV stands for Contact Resistance Variation. It is the instantaneous change in contact resistance that will be encountered as the result of moving the wiper from one position to another. The limit of CRV is expressed as a percentage of the unit’s total resistance or ohms. When the wiper is actuated, the resistance at the wiper terminal, with respect to either end terminal, is apt to increase or decrease by a value within the CRV specification.
