The part number **11004-R** typically refers to a specific series of **High-Precision Surface Mount (SMD) Resistors**, often associated with manufacturers like *Susumu* or *Vishay*, or it may represent a specialized automotive-grade connector component depending on the industry context. In the context of electronic components (specifically thin-film resistors), here is the technical breakdown: ### Technical Specifications Below are the common characteristics for components within the 11004-R designation (Thin Film Chip Resistors): | Feature | Specification | | :--- | :--- | | **Component Type** | Thin Film Precision Resistor | | **Resistance Tolerance** | ±0.1% to ±0.5% (Typical) | | **Temperature Coefficient (TCR)** | ±10ppm/°C to ±25ppm/°C | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Operating Temperature** | -55°C to +155°C | | **Power Rating** | 0.063W to 0.25W (Package dependent) | --- ### Key Features and Applications #### 1. High Stability The "R" suffix often denotes a specific packaging style (Reel) or a precision rating. These parts are engineered for low noise and high reliability over long periods. #### 2. Common Applications * **Medical Electronics:** Precision monitoring equipment. * **Automotive Systems:** ECU mapping and sensor calibration. * **Telecommunications:** Base station signal processing. * **Industrial Control:** Measuring instruments and scales. #### 3. Handling and Storage Since these are often "Thin Film" components, they are sensitive to: * **Electrostatic Discharge (ESD):** Requires grounded handling. * **Moisture:** Often rated at MSL 1 (Moisture Sensitivity Level). --- ### Typical Part Numbering Logic If this part follows the standard industry nomenclature for precision resistors: ```text 11004 - R | | | +-- Packaging Code (Taped & Reeled) +---------- Series/Base Part Number (Size and Material) ``` ---
