ALPS ALPINE RK09K/D 10kΩ B-Taper Potentiometer

The ALPS ALPINE RK09K/D series comprises insulated shaft snap-in rotary potentiometers, engineered for compact applications. These units feature a slim profile with a width of just 9.8mm, making them perfectly suited for high-density PCB assemblies and professional audio equipment where space is at a premium.

Available as a single unit or in a dual resistor element configuration, these potentiometers offer versatile mounting options with both horizontal and vertical types available. The shaft is compatible with flat knobs or can be adjusted via a screwdriver slot, with shaft lengths ranging from 15mm to 30mm to accommodate various panel thicknesses and design requirements. An optional centre detent provides tactile feedback for precise control settings.

The product boasts a broad selection of total resistance values, including 5kΩ, 10kΩ, 20kΩ, 50kΩ, 100kΩ, and 200kΩ, with a standard resistance tolerance of ±20% or ±30%. It offers a generous total rotational angle of either 280° or 300° and supports several resistance tapers (15A, 15C, 1B, 3B) to match different control response curves. Designed for reliable operation, it functions within an operating temperature range of -10°C to 70°C, with a maximum power rating of 0.05W.

Constructed for through-hole mounting with PC pin terminals, this potentiometer ensures a secure and stable electrical connection. Its robust design and precise engineering make it a dependable choice for volume controls, tone adjustments, and any application requiring accurate variable resistance.
