Alps Alpine RK09D1130C1B 10K Potentiometer Original Japan
9 mm Insulated Shaft Snap-in Rotary Potentiometer — Alps / Alps Alpine
Overview
The RK09D1130C1B is a compact 9 mm rotary potentiometer featuring an insulated (plastic) shaft and snap-in panel mounting. With a single turn and a linear taper, it is well suited for low-power electronic adjustment applications where board space is limited.

Features & Benefits
- Compact 9 mm body saves PCB space in tightly packed designs.
- Snap-in panel mounting provides simple and secure front panel installation.
- Linear taper delivers predictable, smooth adjustment for DC control circuits.
- High insulation resistance and dielectric rating suitable for low-voltage safety requirements.
- Reasonable durability (5,000 cycles) for small adjustment duties.
Warnings & Application Notes
- This potentiometer is a low power device (0.05 W). It is not suitable for high current or high power applications.
- Because tolerance is ±20%, it may not be suitable where precise resistance values are critical.
- During soldering, avoid excessive heat: maximum soldering iron tip temperature ≈ 350 °C and exposure ≤ 3 seconds is recommended.
- Contact resistance can affect output with low impedance loads; as a rule of thumb, use load impedances that are much higher than the potentiometer value.
- Avoid exposure to condensation, high humidity, or liquids — these conditions may degrade insulation.
- Long exposed shafts may be sensitive to vibration or external forces; consider mechanical support if needed.
Typical Applications
Volume/level controls, small consumer electronics, front-panel adjustments, prototype boards, and other low-power tuning purposes where a compact, panel-mounted rotary adjustment is required.
