Introduction to Trimmer Potentiometers

A trimmer potentiometer is a type of variable resistor that is typically used to adjust the operating characteristics of a circuit. It is usually made from a thin plastic or ceramic substrate with metal contacts to provide a secure connection for the electrical circuit. Trimmer potentiometers are typically used in electrical circuits where fine-tuning is needed, such as audio amplifiers or voltage regulators. They are typically found in consumer electronics, such as on computer motherboards, amplifiers, and radio receivers.

3386W-1-502RLF Application Field and Working Principle

The 3386W-1-502RLF is a trimmer potentiometer produced by Bourns. It is a 100 ohm trimmer pot with three gang sections. Each gang section can be adjusted independently, allowing fine-tuning of a circuit’s operating characteristics. The 3386W-1-502RLF has a linear taper, meaning that the resistance value changes in a linear fashion as the wiper is moved up or down the resistance path. This type of potentiometer is typically used to adjust the gain or frequency response of an audio amplifier, as well as the bias or voltage reference of a voltage regulator.The 3386W-1-502RLF is compatible with a wide range of voltage sources, ranging from 5V to 32V, and is capable of carrying up to 0.25W of power. It has a maximum resistance of 100 ohms, a tolerance of ±25%, and a resolution of 0.1 ohms. A special feature of the 3386W-1-502RLF is its low-profile design, which is ideal for applications where space is limited.

Conclusion

In conclusion, the 3386W-1-502RLF trimmer potentiometer from Bourns is an ideal solution for fine-tuning the operating characteristics of a circuit. Its low-profile design and wide range of compatible voltage sources make it suitable for a variety of applications, from audio amplifiers to voltage regulators. It features a linear taper for precise adjustment, as well as a maximum resistance of 100 ohms, tolerance of ±25%, and resolution of 0.1 ohms.
