The **PVG3A503C01R00** is a specific model of a **Surface Mount Trimmer Potentiometer** manufactured by Murata Electronics. These components are used for fine-tuning resistance in electronic circuits during the calibration or manufacturing process. --- ## 1. Technical Specifications Below are the core technical parameters for this specific part number: | Property | Value | | :--- | :--- | | **Resistance Value** | 50 kΩ (Kilo-ohms) | | **Tolerance** | ±20% | | **Power Rating** | 0.25W (1/4 Watt) at 70°C | | **Adjustment Type** | Top Adjustment (Single Turn) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Temperature Coefficient** | ±150ppm/°C | | **Operating Temperature** | -55°C to +125°C | --- ## 2. Key Features * **Small Footprint:** The "3A" designation refers to the 3mm square size, making it ideal for high-density circuit boards. * **Cermet Element:** It uses a ceramic-metal (cermet) resistive element, which provides excellent stability and reliable performance under varying temperatures. * **Sealed Construction:** It is typically sealed to withstand automated soldering processes and board washing (IP64 equivalent). * **Rotation:** It is a single-turn potentiometer, meaning the full range of resistance is covered in one rotation (typically around 230° to 270° effective travel). --- ## 3. Part Number Breakdown Understanding the Murata nomenclature helps identify the exact variant: | Code Segment | Meaning | | :--- | :--- | | **PVG3** | Series Name (3mm Square SMD Trimmer) | | **A** | Terminal Shape / Style (J-Hook or Gulls-wing specific) | | **503** | **Resistance Code:** 50 + 3 zeros = 50,000 Ω (50kΩ) | | **C01** | Individual Specification / Design Revision | | **R00** | Packaging Code (usually signifies Tape & Reel) | --- ## 4. Common Applications These components are not meant for end-user interaction (like a volume knob). Instead, they are "set and forget" components used in: * **Signal Calibration:** Adjusting gain in operational amplifiers. * **Sensors:** Fine-tuning the threshold of a sensor circuit. * **Power Supplies:** Adjusting voltage regulators to a precise output levels. * **LCD Modules:** Adjusting contrast or backlight brightness.
