BOURNS 3214 Series SMD Trimmer Potentiometer, Cermet, 20K Ohm, 5-Turn
BOURNS 3214 Series SMD trimmer, 20K ohm, 5-turn cermet element. Top-adjust, AEC-Q200 qualified for precise PCB calibration.
The BOURNS 3214 Series SMD Trimmer Potentiometer is a high-quality, surface-mount adjustable resistor designed for precision circuit tuning in compact electronic assemblies. It utilises a robust cermet resistive element, offering stable performance and long-term reliability. This multi-turn trimmer provides exact adjustment over five full rotations, allowing for fine-tuning of voltage, current, or signal levels with exceptional accuracy.
Housed in a compact 4mm square SMD package, it is ideal for space-constrained PCB designs. The top-adjustment style facilitates easy access for calibration during production or servicing. With a resistance value of 20 kiloohms and a power rating of 250 milliwatts, it is suited for a wide range of low-power analogue adjustment applications in consumer, industrial, and automotive electronics.
