The **FCR-H0-R** is a specific electronic component, typically categorized as a **High-Power Chip Resistor** or a specialized **Fixed Resistor**, often associated with manufacturers like *Kamaya* or similar electronic component providers. These resistors are designed for surface-mount technology (SMT) and are characterized by their reliability and power handling. --- ### 1. Technical Specifications The part number follows a standardized nomenclature. Below is a breakdown of the typical electronic characteristics for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Thick Film Chip Resistor | | **Resistance Range** | 1Ω to 10MΩ (Standard) | | **Tolerance** | ±1%, ±2%, or ±5% | | **Temperature Coefficient** | ±100ppm/°C to ±400ppm/°C | | **Operating Temperature** | -55°C to +155°C | | **Mounting Type** | Surface Mount (SMD/SMT) | ### 2. Physical Construction The FCR-H0-R is built using "Thick Film" technology, which involves several layers: 1. **Substrate:** A high-purity Alumina (ceramic) base for heat dissipation. 2. **Resistive Element:** A metal glaze layer fired onto the substrate. 3. **Protective Coating:** A glass or epoxy resin layer to protect against moisture and mechanical stress. 4. **Terminations:** Tin (Sn) over Nickel (Ni) plating to ensure high solderability and prevent "leaching" during the assembly process. ### 3. Key Features * **High Power-to-Size Ratio:** Designed to handle higher wattages than standard general-purpose resistors of the same footprint. * **AEC-Q200 Compliance:** Often used in automotive applications due to its ability to withstand harsh environments and thermal cycling. * **RoHS Compliant:** Lead-free construction meeting international environmental standards. ### 4. Common Applications * **Automotive Electronics:** Engine control units (ECUs), lighting systems, and infotainment. * **Industrial Power:** Power supply circuits and motor controllers. * **Consumer Electronics:** Power adapters and high-drain battery-operated devices. ---
