The **R16TLJ-R** refers to a high-precision, low-profile rotary potentiometer, commonly manufactured by companies like **Noble** or **Alpha**. It is widely used in audio equipment, industrial controls, and household appliances where space is limited and reliability is required. --- ### 1. Technical Specifications The following table summarizes the general electrical and mechanical characteristics typical of the R16TLJ series: | Parameter | Typical Value | | :--- | :--- | | **Element Type** | Carbon Film / Conductive Plastic | | **Resistance Range** | 1kΩ to 500kΩ (Standard) | | **Power Rating** | 0.05W to 0.1W | | **Maximum Voltage** | 50V AC / 20V DC | | **Rotational Angle** | 300° ± 5° | | **Rotational Life** | 15,000 cycles | | **Mounting Type** | Through-hole (PCB) or Panel Mount | --- ### 2. Physical Design & Features The "R16" designation usually indicates a **16mm diameter** body size. The specific "TLJ-R" suffix often denotes particular physical configurations: * **Low Profile:** Designed with a thin body to fit into compact enclosures. * **Metal Shaft:** Usually features a "D-shape" or "Flatted" shaft for secure knob attachment. * **Snap-in Terminals:** The pins are often shaped to "snap" into a PCB, holding the component in place before soldering. * **RoHS Compliant:** The "-R" suffix commonly signifies compliance with environmental regulations regarding lead-free materials. --- ### 3. Pinout Diagram Most R16 series potentiometers follow a standard 3-pin configuration: ```text [ SHAFT ] / \ | [BODY] | |_____________| | | | 1 2 3 <-- Pins 1: Ground / CCW Terminal 2: Wiper (Output) 3: Input / CW Terminal ``` --- ### 4. Common Applications * **Audio Gear:** Volume and tone controls for guitar pedals, mixers, and portable amplifiers. * **Consumer Electronics:** Temperature or timer settings on kitchen appliances. * **Industrial:** Speed controllers for small motors or dimming controls for LED panels. ---
