Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Resistance Value** | 50 kΩ (503) | | **Resistance Tolerance** | ±20% | | **Power Rating** | 0.25W (1/4 Watt) at 70°C | | **Number of Turns** | 1 (Single-turn) | | **Adjustment Type** | Top Adjustment | | **Temperature Coefficient** | ±150ppm/°C | | **Operating Temperature** | -55°C to +125°C | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Size / Dimension** | 3.2mm L x 3.4mm W x 2.3mm H | --- ### 2. Part Number Breakdown The alphanumeric code follows Murata’s standard naming convention: * **PVG3**: Series name (3mm Square SMT Trimmer). * **G**: Terminal shape (G-wing / Lead shape). * **503**: Resistance code. The first two digits (50) are significant figures, and the third (3) is the multiplier ($10^3$). $50 \times 1,000 = 50,000\,\Omega$ (50 kΩ). * **C01**: Individual specification code (Internal design/materials). * **B00**: Packaging code (Bulk packaging). --- ### 3. Construction and Features * **Cermet Element:** It uses a Ceramic-Metallic (Cermet) resistive element, which offers better stability and lower noise compared to carbon composition types. * **Sealed Construction:** The device is typically sealed to withstand automated soldering processes (reflow) and board washing (cleaning solvents). * **Compact Footprint:** Designed for high-density circuit boards where space is a premium. * **Linear Taper:** The resistance changes linearly relative to the rotation of the adjustment screw. --- ### 4. Applications This specific part is commonly found in: * **Power Supplies:** For fine-tuning output voltage. * **Sensors:** Calibrating threshold levels or sensitivity. * **Communication Equipment:** Matching impedance or adjusting signal gain. * **Industrial Controls:** Calibrating instrumentation and measurement devices.
