The **PV36P503C01B00** is a high-precision electronic component manufactured by **Murata Electronics**. It belongs to the PV36 series of multi-turn trimming potentiometers (trimpots). --- ### 1. General Specifications This component is a variable resistor designed for fine-tuning circuit parameters during the manufacturing or calibration process. | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Murata Electronics | | **Series** | PV36 | | **Resistance Value** | 50 kΩ (indicated by "503") | | **Resistance Tolerance** | ±10% | | **Adjustment Type** | Top Adjustment | | **Number of Turns** | 25 Turns (Mechanical) | | **Power Rating** | 0.5W (1/2 Watt) at 70°C | | **Temperature Coefficient** | ±100ppm/°C | | **Mounting Type** | Through Hole | --- ### 2. Part Number Breakdown The alphanumeric code follows a specific logic used by Murata: * **PV36**: Series name (Lead-sealed, 25-turn, 9.6mm square). * **P**: Adjustment style (Top adjustment, side-view leads). * **503**: Resistance code. The first two digits (50) are significant figures, and the third (3) is the multiplier (10^3). Result = 50,000 Ω or **50 kΩ**. * **C01**: Internal design/packaging specifications. * **B00**: Bulk packaging code. --- ### 3. Physical & Functional Features * **Precision Control:** Being a **25-turn** potentiometer, it allows for extremely granular adjustments. Each full rotation of the screw only changes the resistance by approximately 4% of the total range. * **Sealed Construction:** It is typically "lead-sealed" (watertight), meaning it can withstand board washing processes and harsh environments without the internal resistive element being contaminated. * **Wiper Mechanism:** It uses a cermet (ceramic-metal) resistive element, which provides better stability and lower noise compared to carbon-based potentiometers. --- ### 4. Common Applications Due to its high precision and stability, the PV36P503C01B00 is commonly found in: 1. **Industrial Controls:** Setting gain or offset in operational amplifiers. 2. **Power Supplies:** Fine-tuning output voltage or current limits. 3. **Sensors:** Calibrating threshold levels for analog sensors. 4. **Medical Equipment:** High-reliability signal conditioning. ---
