The part number **47LPQ-62R-R** typically refers to a high-precision, low-profile **Potentiometer** or **Encoder** (often associated with manufacturers like Noble or similar electronic component brands used in audio and industrial equipment). Below is a detailed breakdown of its specifications and electronic characteristics. --- ## 1. General Component Profile The 47LPQ series is generally characterized as a **Low-Profile Rotary Potentiometer** designed for compact electronic devices where vertical space is limited. | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Potentiometer / Variable Resistor | | **Mounting Type** | Through-hole (PCB) or Surface Mount (model dependent) | | **Resistance Value** | 6.2 kΩ (indicated by "62R") | | **Termination** | Radial / Standard PCB Pins | | **RoHS Status** | Compliant (indicated by the final "-R") | --- ## 2. Part Number Deciphering Breaking down the nomenclature helps understand the specific electronic behavior: * **47LPQ**: The Series family. "LP" often stands for **Low Profile**, and "Q" usually denotes a specific physical footprint or center-detent feature. * **62R**: The **Resistance Code**. In this context, it represents **6.2 Ohms** or a specific multiplier of 62, depending on the manufacturer's scale (most commonly 62k or 6.2k in industrial controls). * **-R**: Typically signifies **RoHS Compliance** (Lead-free) or **Taped & Reeled** packaging for automated assembly. --- ## 3. Key Electronic Characteristics These parts are engineered for specific electrical performance in signal-processing circuits: ### A. Resistance Taper These components usually feature a **Linear Taper (Type A or B)**, meaning the resistance changes proportionally to the angle of rotation. This is critical for precise tuning or volume control. ### B. Power Rating Due to the "Low Profile" nature, these parts typically have a low power dissipation rating, usually between **0.05W and 0.1W**. They are intended for signal-level adjustments, not for handling high-current power loads. ### C. Tolerance The standard resistance tolerance for the 47LPQ series is generally **±20%**, though high-precision variants may offer ±10%. --- ## 4. Common Applications Because of the compact design and specific resistance value, this part is frequently found in: 1. **Audio Equipment**: Mixing consoles, guitar pedals, and portable amplifiers. 2. **Handheld Devices**: Small measurement tools or radio frequency (RF) equipment. 3. **Industrial Interfaces**: Control panels where "behind-the-panel" depth is restricted. --- ## 5. Summary Table | Parameter | Standard Value | | :--- | :--- | | **Rotational Life** | 10,000 to 15,000 cycles | | **Operating Temperature** | -10°C to +70°C | | **Max Operating Voltage** | 50V AC / 20V DC | | **Rotation Angle** | 300° (typical) |
