Visão Geral
Description
B72214S2321K101 is a miniature sealed trimming potentiometer (trimmer) in the B72214S family. It is an adjustable resistor used to calibrate circuits, tune offsets or gains, and set reference levels in compact PCB designs. The device is mounted on the board as an SMT component with three terminals and a top-access screw for adjustment; it is sealed to protect against dust and moisture and is suitable for reflow soldering.
The suffix 2321K101 encodes the nominal resistance and tolerance (K = ±10%), plus date/lot information. Exact electrical specifications (end-to-end resistance, travel, power rating, temperature coefficient, etc.) are defined in the manufacturer’s datasheet for this specific variant. If you’re selecting one, verify the precise resistance value and mechanical/thermal specs in the datasheet to ensure fit and performance.
