3361P-1-503GLF

Trimmer potentiometers, or trimmer pots, are adjustable miniature devices used in a wide variety of electrical and electronic applications. The 3361P-1-503GLF is a miniature, single-turn, panel-mountable trimmer pot with a 3.2 mm shaft and a 6.3 mm vertical mounting hole. It has an operating temperature range of -40 °C to 85 °C and a tolerance of ±20%. The 3361P-1-503GLF is keyed and has detent action with 25 turns (360°).

Application Fields

Trimmer potentiometers are used for setting, balancing, or adjusting electrical circuits. They are often used in the control and calibration of radio systems, adjusting gain and feedback circuitry, adjusting load characteristic of amplifiers, and to adjust the frequency of tone controls. The 3361P-1-503GLF is ideal for applications where space is at a premium. Its miniature size and panel-mounting capabilities make it a great choice for mobile and embedded applications. Its range of operating temperatures makes it suitable for a variety of environmental conditions.

Working Principle

Trimmer potentiometers work on the same principle as standard potentiometers. The 3361P-1-503GLF has a circular track of resistance material, typically carbon, that is connected between two ends of the pot. As the control knob is turned, a wiper moves along the track and changes the resistance between the two ends. As the resistance increases or decreases, it affects the signal that is being sent through the circuit.

The 3361P-1-503GLF is a single-turn trimmer. This means that as the control knob is turned, the resistance changes only once, and it does not repeat itself as with multi-turn trimmer pots. The 3361P-1-503GLF is a detent-style, meaning that the control knob has a noticeable "clicking" action as it is rotated at each of the 25 turns. This helps provide tactile feedback and a more precise control to the user.

Conclusion

The 3361P-1-503GLF trimmer pot is an ideal choice when space and accuracy are must-haves. Its small size and detent action allow for precise control of circuits and systems. The miniature, single-turn, panel-mountable design makes it an excellent choice for mobile and embedded applications. Additionally, it’s resistant to corrosion, and its wide operating temperature range makes it especially suitable for tough environmental conditions.
