The part number **47LPQ-A2YR-R** refers to a high-performance **Electrolytic Capacitor**, specifically from the **LPQ series** manufactured by **CapXon**. These components are typically used in power supply filtering and energy storage applications. --- ## Technical Specifications Below is a breakdown of the typical characteristics for this specific series and part configuration: | Feature | Specification | | :--- | :--- | | **Component Type** | Aluminum Electrolytic Capacitor | | **Terminal Style** | Snap-in (2-pin) | | **Capacitance Range** | High Capacity (Depends on specific voltage rating) | | **Temperature Range** | -40°C to +85°C (Standard LPQ Rating) | | **Load Life** | 2,000 hours at 85°C | | **RoHS Status** | Compliant (Indicated by "-R" suffix) | --- ## Part Number Decoder Understanding the alphanumeric string helps identify the physical and electrical properties: ### 1. Series Code: **LPQ** The **LPQ series** is a standard snap-in type capacitor. It is designed for general-purpose high-voltage circuits. These are commonly found in: * Switching power supplies. * Uninterruptible Power Supplies (UPS). * Industrial frequency converters. ### 2. Physical Design: **A2YR** * **A:** Usually denotes the lead/terminal configuration (Standard Snap-in). * **2YR:** This segment typically encodes the **Case Size** (Diameter x Height) and the **Voltage Rating**. For the LPQ series, these are often large cans (e.g., 22mm to 35mm in diameter). ### 3. Compliance: **-R** * **-R:** Indicates that the part is **RoHS Compliant**, meaning it is manufactured without hazardous substances like lead or cadmium. --- ## Key Applications These parts are "workhorses" in power electronics. Their primary roles include: 1. **DC-Link Smoothing:** Flattening the ripples in rectified AC voltage to provide a stable DC bus. 2. **Bulk Storage:** Holding energy to maintain power during brief input voltage drops. 3. **Inverters:** Used in solar or motor drive inverters to stabilize the input stage. --- ## Precautions for Use * **Polarity:** These are polarized components. Reverse voltage will cause the safety vent to open or the capacitor to explode. * **Voltage Derating:** For maximum longevity, it is recommended to operate the capacitor at 80% or less of its rated voltage. * **Heat:** Ensure adequate airflow, as ESR (Equivalent Series Resistance) generates internal heat during high ripple current operations.
