Trimmer Potentiometers are a type of variable resistor used for the fine adjustment of electrical components and circuits. They are primarily used to adjust parameters such as the frequency of oscillators, the gain of amplifiers and the time constants of filters.

The 3303X-3-504E trimmer potentiometer is a sealed, edge insulated fixed pattern potentiometer that provides precision trimming of resistive components in surface-mount technology. Suitable for applications such as RF/microwave, audio, and power supplies, this trimmer has a resistance of 5 kΩ and a tolerance of ±10%.

The 3303X-3-504E is ideal in applications where a surface mount variable resistor is not available or not suitable. Its slim design, sealed construction, and temperature stability make it perfectly suited for applications which require small or limited space.

The 3303X-3-504E trimmer potentiometer works on a similar principle to linear potentiometers. It is designed to act as a voltage divider, which allows for the user to control the voltage ratio between two terminals. When turning the potentiometer knob or adjusting screw, the wiper arm slides across the resistive element, breaking the resistive element into two parts of different resistances. This change in resistance causes the voltage between the terminals to change. With a multiturn potentiometer, such as the 3303X-3-504E, the shaft can be turned several times, allowing for fine-tuning of voltage levels.

The 3303X-3-504E trimmer potentiometer is available from Mouser Electronics with a variety of range and types. It is supplied with an insulation resistance of 500MΩ to earth, insulation resistance of 50MΩ at 1kVDC, and a voltage rating of 20VAC/DC. The temperature coefficient is ±300 PPM/°C. This trimmer is available with solder or glue tab pin or PCB terminal modifications.

The 3303X-3-504E trimmer potentiometer is an ideal choice for applications requiring fine adjustment of electrical components or circuits. It is capable of operating in extreme temperatures, making it suitable for use in the most demanding conditions. Its sealed construction and slim design make it perfect for use in confined spaces, and its high voltage rating ensures that it is suitable for use in RF/microwave and audio applications.
