Trimmer Potentiometers

Trimmer potentiometers are variable resistors that you can adjust for optimal electrical performance in circuits. They are extensively used to precisely adjust signals in sample-and-hold circuits, automatic gain control (AGC) circuits, and in filters and other analog circuits, as well as for adjusting variable resistors, such as potentiometers and rheostats. The 3303C-1-105E is a trimmer potentiometer that offers superior features and performance, making it perfect for applications in which a high degree of precision and reliability are required.

Application Field

The 3303C-1-105E is specially designed to meet the performance requirements of a wide range of applications, including telecommunications, instrumentation and consumer electronics, such as microphones, processors and cell phones. It is ideal for use in circuits where multiple adjustments are needed, such as in AGC, mixers, and automatic tuning systems, as well as for high-voltage protection and signal processing. The 3303C-1-105E is also applicable to the general trimming of the middling point of the common-base frequency of transistors, joystick applications, and the adjustment of power gain in variable audio systems.

Working Principle

The 3303C-1-105E circuit operation works similarly to a variable resistor. It is designed to be rotated from one end of its range to the other, allowing the user to adjust the resistance of the circuit. It is a dual-gang potentiometer, meaning it has two wiper assemblys present on one shaft. This design allows for both lower and higher resistances to be changed simultaneously. Additionally, the 3303C-1-105E has a spring-loaded construction, which ensures that any accidental downwards force will not cause the shaft to move excessively.

The 3303C-1-105E trimmer features a high-precision design, which offers maximum reliability and superior performance. Its power rating is 0.5W, which means it can handle up to 0.5 watts of power without exceeding its operating temperature. Furthermore, the 3303C-1-105E\'s resistance range is adjustable from 0 to 29.5K Ohms, allowing for fine adjustments over a wide range of values. Additionally, the 3303C-1-105E has a low internal capacitance of 0.2pf, which helps to reduce noise and distortion in the circuit.

The 3303C-1-105E trimmer potentiometer is also RoHS compliant, meaning it meets all the applicable European environmental safety regulations. Additionally, it is available in both through-hole and surface mount packages, offering the user a choice of configurations. The 3303C-1-105E is an ideal option for applications in which maximum performance and reliability are required.
