RV09 Horizontal Mini POT Potentiometer 50KΩ

Description

RV09 50 KΩ Horizontal Mini Potentiometer — Key Specs & Features

 Electrical & Resistance Characteristics

• Total Resistance: 50 KΩ

• Tolerance: ± 20 % nominal.

• Resistance Taper: Linear (“B” taper).

• Maximum Operating Voltage: 50 V AC or ~20–12 V DC (depending on datasheet version).

• Power Rating: 0.05 W (typical small-signal potentiometer rating).

• Insulation Resistance: ≥ 100 MΩ (at 250 V DC).

• Maximum Contact / Residual Resistance (end-to-end wiper to end): ≤ approx. 20 Ω (varies slightly by batch/variant).

Mechanical / Physical Properties

• Package / Mounting: Through‑hole / PCB‑mount, 3-pin rotary potentiometer.

• Shaft

  • Type: Knurled / serrated shaft (spline) — common for front-panel knob mounting.

  • Diameter: ~ 6 mm.

  • Shaft Length: varies — horizontal (“mini”) versions often have short shaft ~7–12 mm depending on version.

• Rotation / Angle / Taper

  • Single-turn potentiometer (one full sweep).

  • Typical total rotation angle: ~ 280° ± 5° (some versions list 280–300°).

• Mechanical Life: ~10,000 cycles typical for RV09 series.

• Body Size / Footprint: Compact / miniature, suitable for PCB-mounted controls — good for small PCBs / low‑profile enclosures.

 Use‑case & Typical Applications

• Ideal as adjustable resistor or voltage divider in analog circuits.

• Commonly used for volume controls, contrast/brightness controls, trim potentiometers, analog input adjustment, parameter tuning in DIY electronics.

• Good for microcontroller‑interfaced circuits where you read the wiper voltage via ADC (e.g. Arduino, STM32, ESP32), especially when you need 0–100 kΩ range.

• Suitable for panel-mounted knobs (with knob/spline) — useful in front-panel controls, DIY devices, custom equipment, etc.
