3318S-1-504A

Trimmer Potentiometers are used to provide a variable voltage that is adjusted by a knob or slider for purposes such as adjusting the frequency or signal gain in an electronic application. The 3318S-1-504A Trimmer Potentiometer is a small size variable resistor designed for use in applications requiring a high level of precision. This unit is constructed from a nickel-coated plastic housing with a debossed center shaft and a 5-turn cermet element.

The 3318S-1-504A features a durable construction which makes it suitable for multiple markets across varying temperature ranges. This trimmer potentiometer has a maximum voltage rating of 25 volts with a current rating of 0.5 amps and a power rating of 0.125 watts. Its total resistance is 10Kohms with a tolerances rate of 20%.

The 3318S-1-504A can be used as a variable voltage in applications such as volume control in audio systems, signal gain control for amplifiers, and electronic circuit adjustments. It can also be mounted in a PCB to create a more permanent application. It is important to note that the 3318S-1-504A Trimmer Potentiometer is not designed to be used as an on/off switch, as this may cause shorting.

The working principle of the 3318S-1-504A Trimmer Potentiometer is relatively simple. A voltage is applied to the unit which is then distributed through the central shaft to either side of the casing. The amount of voltage applied to either side of the casing can then be adjusted by turning the knob or slider on the trimmer potentiometer. In doing so, the overall resistance of the unit is also adjusted, allowing for more or less voltage to flow through the unit and thus providing a variable voltage output.

The 3318S-1-504A Trimmer Potentiometer is a durable, precise variable voltage tool with a variety of applications. Its heat and shock resistant construction makes it suitable for a wide range of applications, while its small size makes it easily adaptable for use in circuit boards and other tight spaces. The working principle is simple to understand and easy to use, making it ideal for any application requiring a variable voltage.
