The part number **296HD503C3C** belongs to a series of **Rotary Potentiometers** (variable resistors), typically manufactured by **CTS Electronic Components**. These components are widely used for human-interface controls, such as volume knobs or parameter adjustments in industrial and consumer electronics. --- ## Technical Specifications Based on the standard nomenclature for the 296 series, here is a breakdown of the technical attributes: | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Potentiometer | | **Resistance Value** | 50 kΩ (503 code) | | **Tolerance** | ±10% or ±20% (Standard for 296 series) | | **Power Rating** | 0.15 Watts | | **Mounting Type** | Through-Hole (PCB Mount) | | **Size** | 9mm Small Form Factor | | **Rotation Angle** | 280° (Mechanical) | --- ### Part Number Breakdown To understand the specific features of this model, we can decode the alphanumeric string: 1. **296**: Indicates the series (9mm size, compact design). 2. **H**: Refers to the terminal configuration (usually horizontal or a specific pin layout). 3. **D**: Refers to the shaft style (likely a "D-shaped" or flatted shaft). 4. **503**: The resistance code. The first two digits (50) are the value, and the third (3) is the multiplier (10^3). $50 \times 1,000 = 50,000$ Ohms or **50kΩ**. 5. **C3C**: These suffixes generally denote the taper (Linear or Audio), shaft length, and specific packaging/detent options. --- ### Key Applications Due to its small 9mm footprint, this part is ideal for: * **Audio Equipment:** Volume and tone controls for portable speakers or mixers. * **Industrial Controls:** Setting thresholds on sensor modules or timers. * **Consumer Appliances:** Temperature or speed settings on small household devices. * **Test & Measurement:** Calibration offsets on circuit boards. --- ### Features & Advantages * **Compact Design:** The 9mm size allows for high-density PCB layouts. * **Durability:** Designed for thousands of rotations (cycles) without significant signal degradation. * **Versatility:** Available with or without "detents" (the physical "clicks" felt when turning).
