The **10RS-3B-R0-R/C02** is a specialized high-precision resistor assembly, typically categorized as a **Current Sense Resistor** or a **Shunt Resistor**. These components are designed to measure current by monitoring the voltage drop across a known resistance value. --- ### 1. Component Specifications Based on the standard nomenclature for this series, here are the technical characteristics: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Shunt Resistor / Current Sensor | | **Resistance Value** | 10 mΩ (0.010 Ohms) | | **Tolerance** | ±1% or ±0.5% (depending on specific R-rating) | | **Configuration** | 3-Terminal or 4-Terminal (Kelvin Connection) | | **Material** | Metal Alloy / Manganin | | **Mounting Type** | Surface Mount (SMD) or specialized Lead Frame | --- ### 2. Key Features * **Kelvin Configuration:** The "3B" or "4B" variants often utilize a Kelvin (4-wire) measurement technique. This separates the current-carrying path from the voltage-sensing path, eliminating errors caused by lead resistance. * **Low TCR:** Features a low **Temperature Coefficient of Resistance**, ensuring the resistance value remains stable even as the part heats up during high-current flow. * **High Power Dissipation:** Designed to handle significant wattage relative to its size, making it suitable for power management systems. --- ### 3. Application Use Cases These parts are commonly found in precision electronics where power monitoring is critical: 1. **Battery Management Systems (BMS):** Monitoring charge and discharge cycles in electric vehicles or laptop batteries. 2. **DC-DC Converters:** Providing feedback loops for current regulation. 3. **Motor Control:** Detecting overcurrent conditions to protect the motor and circuitry. 4. **Power Supplies:** Real-time load monitoring for server-grade power units. --- ### 4. Part Number Breakdown (Generalized) While manufacturers vary slightly, the code generally follows this logic: ```text 10RS - 3B - R0 - R / C02 | | | | | | | | | +-- Custom Code/Revision | | | +------- RoHS Compliant | | +------------ Resistance Value (R0 = Low Ohmic) | +----------------- Terminal Style (3-Terminal/Busbar) +------------------------ Series Prefix ``` ---
