When it comes to electronic design and circuit control, potentiometers and power supplies (board mount) are two essential components. Whether you’re adjusting resistance for signal tuning or converting voltage for stable power delivery, these devices ensure precision, efficiency, and long-term reliability.
Potentiometers and Variable Resistors
Potentiometers, often called variable resistors, allow users to adjust electrical resistance manually, making them ideal for fine-tuning voltage, current, or signal levels in a circuit. They are widely used in audio equipment, motor controls, measurement instruments, and consumer electronics.
