This group includes adjustable resistive components designed for tuning, calibration, and control in electronic circuits. Potentiometers: Manually adjustable resistors used for setting levels such as volume, brightness, or position in audio equipment, lighting, and control systems. Trimmer Resistors: Compact, adjustable resistors typically used for fine-tuning and calibration in circuits during assembly or maintenance. Rheostats: High-power variable resistors used for controlling current in industrial applications and testing setups. Digital Potentiometers: Electronically controlled variable resistors for precision adjustment in automated systems. These components are vital for achieving precision, flexibility, and control in a variety of consumer, industrial, and automotive applications.
