Technical Specifications | Parameter | Value / Detail | | :--- | :--- | | **Manufacturer** | Susumu | | **Resistance Value** | 0.1 $\Omega$ (indicated by R10) | | **Tolerance** | $\pm$2% (indicated by G) | | **Power Rating** | 1/5W (0.2W) | | **Package Size** | 0603 (Imperial) / 1608 (Metric) | | **Temperature Coefficient** | $\pm$100 ppm/°C | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Part Number Breakdown The part number provides specific details about the component's architecture: * **RL**: Series name (Long-side terminal low resistance chip resistors). * **0816**: Physical dimensions ($0.8mm \times 1.6mm$). Note that Susumu often uses a "long-side terminal" configuration for better heat dissipation and lower inductance. * **R10**: The resistance value. "R" acts as the decimal point ($0.10 \Omega$). * **G**: The tolerance code ($\pm$2.0%). --- ### 3. Key Features and Applications #### Features * **Low Inductance:** Due to the thin-film structure, it exhibits excellent high-frequency characteristics. * **Current Sensing:** Specifically designed to measure current by monitoring the voltage drop across the resistor ($V = I \times R$). * **Stability:** High reliability and stability under harsh environmental conditions. #### Common Applications 1. **Power Supplies:** Monitoring output current in DC-DC converters. 2. **Battery Management Systems (BMS):** Tracking charge and discharge cycles in mobile devices or laptops. 3. **Motor Control:** Detecting overcurrent conditions to protect circuitry. 4. **CPU/ASIC Power:** Precision current monitoring for high-performance processors. --- ### 4. Implementation Example In a typical current-sensing circuit, the RL0816-R10G is placed in series with the load. ```c // Calculation for Voltage Drop Current (I) = 2 Amperes Resistance (R) = 0.1 Ohms (R10) Voltage Drop (V) = I * R V = 2A * 0.1Ω = 0.2 Volts (200mV) ```
