Trimmer Potentiometers OverviewThe trimmer potentiometers, also known as trimpots, variable resistors, or adjustable resistors, have been popular tools for use in various circuits and electronic systems for quite some time. Essentially, these are three-terminal on-board devices that feature a sliding contact beneath the potentiometer shaft. The discrete components are designed to control settings, resistivity and electrical noise in varying circuit designs. Often these trimmer potentiometers are used as adjustable resistors in the place of a soldered, fixed resistor which can be adjusted later if necessary.3362U-1-682R Usage and Working PrincipleThe 3362U-1-682R trimmer potentiometer is particularly useful for applications needing space-savingsolutions. It is constructed with three terminals, a contact wiper, and a helical spring system. This construction enables the miniaturized trimpot to take advantage of the helical spring to offset the electrical noise in the system, while delivering excellent performance.The 3362U-1-682R is available in different configurations. The configuration includes convenient 3-terminal and 4-terminal top adjust and side adjust options, both of which support adjustment working angles of approximately 300°. Additionally, they come with either vertical or horizontal mounting.This trimmer potentiometer is suitable for applications in medical, industrial, consumer, and automotive fields. It has an ohmic range of 10Ω to 10kΩ, and can handle 175mW of power with an operating temperature of -55℃ to 85℃. The 1/2W offset is effective for electrical noise elimiation, improving long-term stability. The life expectancy is typically more than 500,000 cycles, and the resistance tolerance is less than ±20%.It all starts with the construction of the 3362U-1-682R, which includes a helical spring. This helical spring diffuses electrical noise, thus eliminating the need for additional noise suppression features. When the device is switched on, the contact wiper moves along the track to create a variable current. The resistance of the potentiometer can be adjusted by simply increasing or decreasing the current. A jump in voltage or/and current is visible on the voltage or/and current meter when the coil is adjusted.ConclusionThe 3362U-1-682R trimmer potentiometer is a miniature and reliable adjustable resistor device suitable for various electronic and electrical applications. It is extremely useful for applications needing space-savingsolutions, and offers several practical features, including adjustable resistors, excellent performance, robust spring design, and tolerant temperatures. This trimmer potentiometer is ideal for dealing with noise issues in systems, as it is able to diffuse electrical noise to provide excellent long-term performance. Moreover, its resistance tolerance and adjustable angular range make it suitable for many different uses in medical, industrial, consumer, and automotive industries.
