Detailed description of potentiometer products
1. Product Overview
A Potentiometer is a variable resistor component that regulates voltage, current or signals in a circuit by manually rotating or sliding to change its resistance value. It is widely applied in fields such as electronic devices, industrial control, audio equipment, etc.
2. Product model
Type: Rotary/Sliding/Multi-turn/Digital
Resistance range: 10Ω to 2MΩ (customization supported)
3. Technical parameters
Parameter specification
Rated power: 0.1W to 2W (depending on the model)
Resistance tolerance ±10% / ±20% (optional)
Rotation Angle: 270° / 300° / multiple turns (5 turns, 10 turns, etc.)
Interface type pins/pads/shafts (6mm/8mm, etc.)
Operating temperature: -30℃ to +70℃
The mechanical life is ≥10,000 rotations
Protection grade: IP40 (dustproof)/IP67 (waterproof optional)
4. Core Features
High-precision adjustment: Linear or logarithmic resistance value change (A-type/B-type curves are optional).
Durable design: Carbon film/metal film/conductive plastic material, with strong wear resistance.
Wide compatibility: Supports THT (through-hole) or SMT (surface mount Technology) installation methods.
Low noise: Suitable for audio devices (such as volume control).
Optional configuration: With switch/dual/encoder function.
5. Application Scenarios
Consumer electronics: audio volume adjustment, lamp brightness control.
Industrial equipment: Motor speed regulation, instrument and meter calibration.
Automotive electronics: Backlight adjustment for in-vehicle display screens.
DIY project: Used in conjunction with development boards such as Arduino and Raspberry Pi.
6. Packaging and accessories
Standard packaging: 100pcs per bag (or customized according to customer requirements).
Optional accessories: knob, installation nut, dust cover.
7. Certification and Compliance
Comply with RoHS and REACH environmental protection standards.
CE/FCC certification (optional).
8. Precautions
Avoid overpower use to prevent overheating and damage.
The temperature during welding should be controlled below 260℃ (completed within 3 seconds).
