Introduction

Trimmer Potentiometers are small and user-adjustable components, usually found in consumer, automotive, and industrial electronic equipment and products. They are employed to set gain or offset, or to select an input resistance, in various kinds of systems including televisions, amplifiers, radios, and industrial controls. The FT63EH100 is an example of this type of component, and this article will explore its application field and working principles. The FT63EH100 is a dual gang trimmer from Thumbwheel Controls capable of operating at -15°C to +85°C with 0.5W maximum power rating.

Application Field of FT63EH100

The FT63EH100 is a dual-ganged trimmer, meaning that there are two individual groups of elements, each with different resistances that can be independently adjusted. The FT63EH100 is a versatile device due its wide range of possible applications. These include:

• Appliance and consumer device control
• Radio and television volume control functions
• Specialized analog circuitry
• Industrial and automotive vehicle control
• Amplifier balance and switching
• Audio component balancing and matching
• RC servo control
• RF impedance matching

The FT63EH100 is a two-ganged trimmer and therefore needs the additional electrical connection to ground, for both the left and right gangs. This makes it well suited for use in auto-adjustment applications such as radio tuner alignment or in applications requiring independent control of two separate parameters such as amplifier level and tone controls for stereo equipment.

Working Principle of FT63EH100

The FT63EH100 Trimmer Potentiometer is an adjustable resistor. The resistance value changes with the rotation of the range control screw. The resistive element is made from two sheets of conductive material (typically, metal) that are isolated from each other with a thin film of non-conductive material. These two sheets form what is known as a "track" - when the control screw is turned the resistance of the track varies.The FT63EH100 also has a ground contact, which serves to reduce the voltage across the resistor and reduce any vibration or noise that would otherwise be generated. The two gangs (left and right) of the FT63EH100 are connected in parallel, and the ground pin is connected to the common connection of the two gangs. This allows each of the gangs to be adjusted independently. The FT63EH100 is offered in a variety of resistance values, in the range of 100Ω to 10kΩ. Its range of temperature operation is also impressive, ranging from -15°C to +85°C.

Conclusion

The FT63EH100 is an example of a dual-ganged Trimmer Potentiometer, designed for use in a wide range of consumer, industrial and automotive applications. Its impressive temperature and power ratings make it a suitable choice for use in high-performance applications. Its wide range of resistance values allows it to be used in a wide variety of applications and its two gangs offer independent control of two distinct parameters.
