Trimmer Potentiometers

Trimmer potentiometers are adjustable electronic components made of two basic electrical parts: a resistive element and a sliding contact brush. They are typically used as variable components in circuits based on resistors, capacitors, and the like. The TC89P-1-204 is a type of trimmer potentiometer.

The TC89P-1-204 trimmer potentiometer is an ultra-miniature, panel-mounting trimmer with a built-in shaft and a 2-pole switch. It is designed to adjust small capacitive or resistive components, such as those used in radio receivers and transmitters. The unit has a wide operating range of 0.1kΩ to 4.5kΩ and is available in various power ratings including 0.07W, 0.1W, and 0.2W.

The TC89P-1-204 has a small size but offers a wide range of adjusts and easy control. It efficiently resists excessive voltages and heat, and provides an excellent resistance-to-weight ratio. The unit also features a taped construction, which allows for quick and easy mounting in an electronic board.

The TC89P-1-204 trimmer potentiometer works by using its sliding contact brush to adjust the voltage or resistance of a component. This effect is achieved by pressing the contact brush onto the resistive element and varying the pressure to make the resulting resistance or voltage rise or fall. This adjustment can be made by rotating the shaft on the unit or by manually pressing the contact brush onto the resistive element.

The TC89P-1-204 trimmer potentiometer is primarily used in radios and other electronic equipment, where it provides convenient adjustment of capacitive or resistive components without soldering. It is also ideal for finely-tuned signal control and monitoring in outlets with tight packing densities. Additionally, the trimmer is used in AC and DC circuits, as well as further applications such as fine-tuning the sensitivity of Light-Activated Switches (LAS) and Infrared (IR) transmitters/receivers.

In summary, the TC89P-1-204 trimmer potentiometer is an ultra-miniature, panel-mounted unit that is used to adjust the resistance or voltage of resistive or capacitive components. The trimmer is designed for use in radios and other electronic equipment, as well as a wide range of other applications. It features a range of adjustable power ratings and an easy-to-use switching control, making it an ideal choice for controlling and monitoring signals in tightly-packed outlets.
