Trimmer potentiometers are a widely used type of adjustable resistor with three pins. They are also known as "trim pots”. The 3214J-1-502E trimmed potentiometer is one of the most popular trimmer potentiometer types used in various electronic devices due to its stable performance characteristics and low cost. In this article, we will discuss the application field and working principle of the 3214J-1-502E trim pot.

The 3214J-1-502E trim pot is typically used as an adjustable voltage divider in devices such as audio systems, amplifiers, and radio antenna relays. This trim pot has a nominal resistance of 500 ohms and is designed with a three-terminal, plastic-body, through-hole format. It has gold-plated leads to ensure low electrical contact resistance and long life. The 3214J-1-502E trim pot comes with a rotary adjustment knob to adjust the resistance value. The small size and low profile of this trim pot make it easy to install in tight spaces.

The working principle of the 3214J-1-502E trim pot is relatively simple. The three terminals on the trim pot are connected in series and form a voltage divider. The two outer terminals are connected to the power source while the center terminal is connected to the load. By adjusting the rotary knob on the trim pot, the resistance of the internal resistor can be adjusted. This, in turn, changes the voltage ratio between the two outer terminals and the load, thus adjusting the voltage supplied to the load.

In conclusion, the 3214J-1-502E trim pot is a popular type of trim pot. It is typically used as an adjustable voltage divider in various electronic devices such as audio systems, amplifiers, and radio antenna relays. It has three terminals connected in series and is designed with a rotary knob to adjust the resistance value. Its working principle is based on a voltage divider circuit, with the resistance value of the internal resistor being adjusted by the knob to control the amount of voltage reaching the load.
