Trimmer Potentiometers: CT6EV200 Application Field and Working Principle

Trimmer potentiometers or “trim pots” are variable resistors that have three small terminals instead of two. The third terminal is used to adjust the resistance of the pot by changing its internal tapered resistance track position. Trim pots can be used to control and adjust functions within a circuit. CT6EV200 trimmer potentiometers from Bourns are single-turn adjustable precision potentiometers with a 6mm square body profile.

Specifications

The CT6EV200 trim pot is designed to be used in applications where a reliable and accurate adjustment of the output signal is required. This trimmer potentiometer has a resistance value range of 200Ω with 6mm body width and a track resistance tolerance of ±5%. This potentiometer features a low torque of 0.25mA nominal and an operating temperature range of -55°C to +125°C.

Mechanical Specifications

The CT6EV200 trimmer come with plastic busing, either horizontal or vertical. The bushing is 6mm in diameter and has a hex nut or wing nut for easy adjustment. The knob is either a standard knob with black buttons or a “solid” knob with a white button. The solid knob version provides more positiom control of the trimmer. The wiring connection is through two 0.2” pins.

Design and Application Features

The CT6EV200 trimmer offers several design and application features. It is designed for use in industries such as automotive, telecom, and audio-video. Its surface mount package and medium profile make it ideal for board-level applications. It is also suitable for application in printed circuit boards (PCBs) and for use in prototype development and evaluation. The CT6EV200 trimmer can be used in combination with other components to provide a range of adjustable functions. This type of component is ideal for applications where the output needs to be regulated, such as current control, signal calibration and device testing. The low profile 6mm package ensures that the potentiometer does not take up too much space on the PCB. Additionally, the trimmers require minimal force to adjust, making adjustment easier.

Working Principle

The CT6EV200 trimmer works on the principle of variable resistance. It consists of two resistive elements joined by a movable wiper. These elements are connected across an external voltage source. The wiper is shown in the diagram as a central metal rod connected to the resistance element on the bottom of the pot. As the knob is rotated to increase or decrease the resistance of the trimmer, the wiper is physically moved up or down the resistance elements. This, in turn, changes the resistance of the entire circuit.

Conclusion

The CT6EV200 trimmer potentiometer is a type of adjustable precision potentiometer designed to provide reliable and accurate adjustment of the output signal. Its low profile 6mm package makes it suitable for application in PCBs and prototype development. This trimmer pot is ideal for current control, signal calibration and device testing. The resistance of the trimmer can be adjusted by turning the knob, which moves the wiper up or down the resistance element.
