Trimmer Potentiometers are used widely in a variety of industry applications, but the usage and performance characteristics of each product may differ significantly. The91AR50LF is a trimmer potentiometer used in multiple industry applications. Its application field and working principle are examined here.

Application field of 91AR50LF

The 91AR50LF is a single turn adjustment-style trimmer potentiometer designed for surface mounting. It is used in a variety of applications ranging from medical electronics to televisions, computer graphics cards, GPS navigation systems, automotive applications, as well as sensors and regulators.

This trimmer potentiometer has a range of features which make it suitable for use in most applications. It is very reliable and contains a durable case which offers excellent protection from dust, moisture, and other environmental factors. It is a three-terminal device and features a linear resistance-current relationship.

Working principle of 91AR50LF

The 91AR50LF has a linear resistance-current characteristic, which makes it suitable for use in adjustable speed applications, as well as low voltage and low to medium frequency applications. It works by having a central conductive element, which is typically made of metal or carbon, and two resistive elements, which are connected to the central element as the two ends of the element. When a current is applied, the resistors will balance each other out and the current will be split evenly between them. This will create a stable resistance value at the central terminal.

The 91AR50LF has an adjustable terminal, which can be turned to adjust the resistance across the device. This allows fine tuning of the current flow and voltage levels in the system. Depending on the application, this trimmer potentiometer can create a high current pulse or a low voltage threshold in the system.

Conclusion

The 91AR50LF is a trimmer potentiometer used in multiple industry applications, such as sensors, regulators, and other adjustable speed applications. It has a linear resistance-current characteristic, and features an adjustable terminal for fine-tuning. It is very reliable and offers excellent protection to the system.
