Trimmer Potentiometer Single Turn, Vertical 10kΩ CA9PH2.5
The Trimmer Potentiometer Single Turn, Vertical 10kΩ CA9PH2.5 is a compact 9mm carbon film trimmer potentiometer designed for single‑turn through‑hole mounting. Its vertical adjustment rotor allows precise resistance trimming using a standard screwdriver. The dust‑protected housing meets IP54 ingress protection, and the flame‑retardant plastic case is UL 94 V‑0 rated. With a linear taper, 10kΩ resistance, and 150mW power rating, this trimmer is ideal for calibration, offset adjustment, and gain setting in a wide range of electronic circuits.
Features:
- Single‑turn carbon film trimmer with vertical adjustment direction.
- IP54 dust‑protected housing for reliable operation in industrial environments.
- Flame‑retardant plastic case (UL 94 V‑0) for enhanced safety.
- Linear (B) taper characteristic for uniform resistance change.
- Tinned brass terminals with 5.0mm × 2.5mm pitch for secure PCB soldering.
