Trimmer Potentiometers

Trimmer potentiometers are components used to adjust electrical signals in circuits. They are also referred to as trimmer pots, trim pots, or trimpots. The 3057Y-1-500 is a trimmer potentiometer with a power rating of 250 mW and a resistance value of 1 KΩ. This potentiometer is commonly used in audio and video equipment, computers, communication equipment, automotive electronics, and consumer electronics. It is also popular in adjusting the voltage dividers and leveling of various circuits.

Trimmer potentiometers are rotary or linear variable potentiometers with a small footprint that can be adjusted from the side or top of the device. This type of part has the ability to adjust the electrical signal with an external mechanism, such as a small screwdriver. This makes them particularly suited for applications where it is not possible or desirable to manually adjust the electrical signal, such as on printed circuit boards or where precision is required. In addition, a trimmer potentiometer has the ability to provide adjustable solutions at a low cost.

The 3057Y-1-500 is a three-terminal, top adjust trimmer potentiometer. It features a tracking saliency of 1%, which means that the resistance between the wiper and either of the two boards remains within 1% of the total resistance even when the wiper is moved from one side to the other. The device has a temperature coefficient of ±100 ppm/°C, a low profile of 4.1 mm, and a footprint of 4.9 mm x 9 mm. It is designed to operate at temperatures between -25°C and +85°C and it is RoHS compliant.

The 3057Y-1-500 trimmer potentiometer is used in a wide variety of applications. It can be used to adjust the gain and offset of audio amplifiers, amplifier bias, DC bias circuits, DC servos, voltage references, sample and hold circuits, transimpedance amplifiers, filters, and waveform generators. It is also commonly used in adjustable power supplies, commercial radios, RF transmitters, waveform generators, PLLs, and other electronic equipment.

The 3057Y-1-500 trimmer potentiometer has two fundamental operating modes: active/variable operation, where the output voltage is adjusted according to the wiper position, and passive/trim operation, where the device acts as a voltage divider. In passive mode, the device can be used to adjust the level of a DC voltage by adjusting the ratio of two resistances connected in series. In active/variable mode, the output voltage can be adjusted by rotating the knob or screw, or by applying an external control signal.

The 3057Y-1-500 trimmer potentiometer is a versatile, low-cost device that is widely used in a variety of applications. It is designed to provide reliable performance and high precision for adjustable solutions at a low cost. It is also simple to integrate into any circuit, making it a popular choice for engineers and designers.
