3057Y-1-253

Trimmer Potentiometers, or trim pots, are used to adjust resistance in a particular electrical device, typically with a small range of motion or number of clicks. The 3057Y-1-253 is a potentiometer from Bourns, Inc., a corporation that specializes in electronic components and related products. Technically classified as a conductive plastic element, it features a 9.3 mm top adjustment diameter with a 15 to 27 ohm adjustment range.

A trimmer pot operates with two sets of contactplates, known as a fixed terminal and a movable terminal. The movable terminal is moved through a shaft which is in turn connected to a knob or nut that can be turned to adjust the pot. When these two terminals make contact, an electrical connection is established that varies with the amount of resistance in the device. As the trimmer pot is adjusted, the resistance in the device changes, allowing for precise adjustments.

The 3057Y-1-253 is commonly used in applications that require a resistive element such as a volume control, frequency adjustment, or low/high setting. In addition, the trimmer pot is useful for compensating for parameters affected by environmental conditions like temperature and barometric pressure. With its small form factor and easily adjustable knob or nut, the 3057Y-1-253 is an ideal choice for a wide range of applications.

When applying a trimmer pot in an electrical system, there are a few key things to consider. Ensure there is enough room for the trimmer pot to fit and move freely, as any obstructions can affect the movement of the movable terminal and lead to inaccurate readings. In addition, avoid mounts and areas exposed to environmental conditions, as changes in temperature or barometer may cause the trimmer pot to fluctuate. Furthermore, be sure that the contacts of the trimmer pot are rated with a high enough current to support the application it is going into.

The Bourns Inc. 3057Y-1-253 is an excellent choice as a trimmer pot for a wide range of applications. With its compact design and wide range of motion, it can be used to adjust electrical devices accurately and easily. With proper installation and maintenance, it can provide years of reliable performance in any circuitry environment.
