Trimmer Potentiometers

3296Z-1-103 Application, Field, and Working Principle

Trimmer potentiometers are miniature variable resistors, best known for their ability to adjust electronics. The 3296Z-1-103 is a model type of trimmer potentiometers manufactured by Bourns. This trimpot allows for vertical and horizontal mountings. It is a three-terminal device with a ceramic body or with plastic built-in screws, ideal for fine adjustments to be performed.

Application

Trimmer potentiometers like the 3296Z-1-103 are among the most commonly used in the field of electronic engineering for fine or coarse adjustments. These potentiometers can be used in a wide range of applications such as radio receivers, amplifiers, keyboards, and personal computers, among others. Their compact passivated metalized (CPCM) technology makes them robust devices, resistant to environmental influences.

Field of Use

The 3296Z-1-103 is considered a device suitable for operation in high noise and vibration environments. In particular, it is intended for use in industrial automation, automotive, off-road, robotic, telecommunication, consumer, and computer applications. It is well suited for use in functions related to industrial controls, servomotors, speed control, frequency control, and home-appliance regulation.

Working Principle

Trimmer potentiometers work in the same way as other resistors. It consists of a track or armature, a solid state wiper element, and a mechanical contact piece. The track or armature determines the resistance value. The wiper is the mechanical point of contact between the track and the voltage source. The mechanical contact is responsible for connecting the circuit and provides the link between the track and the voltage source.When a voltage is applied to the 3296Z-1-103, the wiper moves along the track and adjusts the current in the circuit. The resistance of the track can be adjusted by moving the contact point along the track. The 3296Z-1-103 features an Offer range of 100 ohms to 500KOhms, with individual steps of 1 ohm to 1KOhms. Its features also include an operating temperature of -55°C to +150°C, a voltage rating of 10Vdc or 20Vdc, an insulation resistance of 100MOhms to 500Vdc, and a relatively high rotational life of 1,000 cycles for standard applications.

Conclusion

The 3296Z-1-103 trimmer potentiometer is one of the most widely used models among engineers. This potentiometer is especially suitable for applications in noise and vibration environments such as industrial automation, automotive, off-road, robotic, telecommunication, consumer, and computer applications. With its robust CPCM technology, it is able to withstand environmental influences and provide reliable and accurately adjusted results. Its wide range of adjustment also provides the flexibility needed to ensure precise operation.
