The **PVC6H503C01B00** is a high-precision trimmer potentiometer manufactured by **Murata Electronics**. It belongs to the PVC6 series, which is characterized by its square, single-turn, through-hole design. Below is a detailed breakdown of its electronic and physical specifications. --- ### 1. Key Technical Specifications | Parameter | Specification | |:---|:---| | **Manufacturer** | Murata Electronics | | **Series** | PVC6 | | **Resistance Value** | 50 kOhms (indicated by "503") | | **Tolerance** | ±10% | | **Power Rating** | 0.5W (1/2 Watt) at 70°C | | **Temperature Coefficient** | ±100ppm/°C | | **Adjustment Type** | Top Adjustment | | **Number of Turns** | 1 (Single-turn) | | **Mounting Type** | Through Hole | | **Termination Style** | PC Pins | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying the specific variant of this component: * **PVC6**: Series name (6mm Square, Cermet element). * **H**: Terminal style (H refers to the lead shape/arrangement). * **503**: Resistance code. The first two digits (50) are the significant figures, and the third digit (3) is the multiplier ($10^3$). Thus, $50 \times 1,000 = 50,000$ Ohms or **50kΩ**. * **C01**: Internal subdivision/design code. * **B00**: Packaging code (Bulk). --- ### 3. Construction and Material * **Resistive Material:** Cermet (Ceramic-Metal). This provides high stability, low noise, and a long life cycle compared to carbon-based potentiometers. * **Housing:** High-temperature plastic, often rated for industrial environments. * **Sealing:** This series is typically "Sealed," meaning it can withstand board washing processes after soldering without the internal resistive element being contaminated. --- ### 4. Application Areas This component is used for "set-and-forget" adjustments in electronic circuits: * **Voltage Regulation:** Calibrating power supply outputs. * **Sensor Calibration:** Adjusting the gain or offset of an analog sensor. * **Timing Circuits:** Tuning the RC constant in oscillator circuits. * **Industrial Equipment:** Used in control systems where precision and durability are required. --- ### 5. Mechanical Dimensions (General) The PVC6 series usually follows a standard **6.0mm x 6.0mm** footprint with a height of roughly **4.1mm**. The leads are arranged in a triangular pattern to ensure stability on the PCB.
