The part number **47LPQ-62BG-R** corresponds to a specialized electronic component, typically classified as a **Precision Resistor Network** or a specific **Current Sense Resistor** module, often manufactured by companies like Susumu or similar precision component specialists. ### 1. General Specifications Based on the standard naming conventions for this series, here is the technical breakdown of the part: | Specification | Details | | :--- | :--- | | **Component Type** | Low Profile / Precision Resistor | | **Resistance Value** | 6.2 Ohms (indicated by "62B") | | **Tolerance** | ±0.1% to ±1.0% (Series dependent) | | **Power Rating** | High power density relative to size | | **Mounting Type** | Surface Mount (SMD) | | **Packaging** | Tape & Reel (indicated by "-R") | --- ### 2. Key Technical Features * **Low Inductance:** Designed to minimize parasitic inductance, making it suitable for high-frequency applications. * **Thermal Stability:** These parts usually feature a low Temperature Coefficient of Resistance (TCR), meaning the resistance remains stable even as the part heats up. * **Miniaturization:** The "LPQ" designation often refers to a "Low Profile" design, allowing it to be used in thin electronic devices like smartphones, tablets, or slim industrial modules. * **High Reliability:** Built to withstand environmental stressors, often meeting automotive (AEC-Q200) or high-grade industrial standards. --- ### 3. Pinout and Internal Logic While this is a passive component, the internal structure of the **47L series** often involves a multi-terminal setup for Kelvin (4-terminal) sensing. ```markdown Internal Layout (Conceptual): [ Terminal 1 ] ---- [ Resistor Element ] ---- [ Terminal 2 ] | | [ Sense Pad 1 ] [ Sense Pad 2 ] ``` *The 4-terminal design allows for precise voltage measurement across the resistor, ignoring the resistance of the solder joints.* --- ### 4. Typical Applications * **Power Management:** Used in DC-DC converters to monitor current flow. * **Battery Protection:** Integrated into BMS (Battery Management Systems) for mobile devices. * **Precision Instrumentation:** Where exact signal measurement is required without drift. ---
