The part number **10RS-0D-R0-R** typically refers to a high-precision, low-profile **Chip Resistor** or a specific series of **Current Sense Resistors**, often associated with manufacturers like *Rohm Semiconductor* or *Cyntec*. Below is a breakdown of the typical electronic specifications and characteristics associated with this part number. --- ### 1. General Specifications | Feature | Typical Value | | :--- | :--- | | **Component Type** | SMT (Surface Mount Technology) Resistor | | **Resistance Value** | 10 mΩ (0.010 Ohms) | | **Tolerance** | ±0.5% or ±1.0% (Depending on series) | | **Power Rating** | 0.5W to 1W (Size dependent) | | **Operating Temperature** | -55°C to +155°C | | **Construction** | Metal Plate or Thick Film | --- ### 2. Part Number Nomenclature (Typical Breakdown) While exact codes vary by manufacturer, the string is usually interpreted as follows: * **10R**: Represents the resistance value. "10R" in the context of low-ohmic sensing usually indicates **10 milliohms (0.01Ω)**. * **S**: Often denotes the **Size** or the **Series** (e.g., Short-side terminal or Small form factor). * **0D**: Usually a code for the **Tolerance** (e.g., D = ±0.5%) or a specific **Temperature Coefficient (TCR)**. * **R0-R**: Indicates the packaging format, typically **Tape and Reel (T&R)**. --- ### 3. Key Applications Because this is a low-resistance (mΩ) component, it is primarily used for **Current Sensing**. 1. **Power Management:** Monitoring current flow in battery-powered devices. 2. **DC-DC Converters:** Providing feedback for voltage regulation and overcurrent protection. 3. **Motor Control:** Detecting the torque and load of small electric motors. 4. **Automotive Electronics:** Used in ECU modules for precise power distribution. --- ### 4. Technical Advantages * **Low Inductance:** Metal plate construction ensures minimal signal distortion at high frequencies. * **High Stability:** Excellent TCR (Temperature Coefficient of Resistance) ensures the resistance doesn't drift significantly as the part heats up. * **Compact Footprint:** Designed for high-density PCB layouts. ---
