The designation **1-C6-R** is most commonly associated with a specific electronic component: a **surface-mount (SMD) capacitor**, typically identifying its dielectric material, capacitance value, and physical characteristics. Below is a detailed breakdown of what this part represents in the context of electronic components. --- ## 1. Component Identification In the electronics industry, "1-C6-R" often refers to a series of **Multi-Layer Ceramic Capacitors (MLCC)** or sometimes specific **Surface Mount Inductors**, depending on the manufacturer (such as Murata or TDK). | Feature | Description | | :--- | :--- | | **Component Type** | Passive Surface Mount Device (SMD) | | **Primary Function** | Energy storage, filtering, or decoupling in a circuit | | **Common Dielectric** | Often associated with High-Q or X7R/X5R materials | | **Termination** | RoHS compliant (Lead-free) | --- ## 2. Technical Specifications Breakdown While codes can vary slightly by manufacturer, the alphanumeric string "1-C6-R" usually follows this logic: ### A. The "1" (Voltage/Size Prefix) * Usually indicates a **Voltage Rating** (e.g., 10V or 100V) or represents the **Quantity/Packaging** code in a distribution system. ### B. The "C6" (Value/Material Code) * **Capacitance:** In many systems, '6' represents a multiplier. * **Dielectric:** In Japanese manufacturing standards, "C" can refer to Temperature Coefficient (TC). C0G (NP0) is a common stable dielectric used in these parts, known for low drift with temperature changes. ### C. The "R" (Tolerance or RoHS) * **Tolerance:** "R" is often used to denote a decimal point (e.g., 1R5 = 1.5) or a specific precision tolerance. * **Compliance:** In modern part numbers, the suffix "R" almost always stands for **RoHS Compliant**, meaning the part is free from lead and other hazardous substances. --- ## 3. Physical Characteristics These parts are typically found in standard SMD package sizes. ### Package Dimensions The most common sizes for this type of part are: * **0402:** 1.0mm x 0.5mm * **0603:** 1.6mm x 0.8mm * **0805:** 2.0mm x 1.25mm ### Application Usage 1. **Decoupling:** Placed near Integrated Circuits (ICs) to suppress noise. 2. **RF Circuits:** Used in high-frequency matching networks if the dielectric is C0G/NP0. 3. **Power Management:** Used in DC-DC converters for output smoothing. --- ## 4. Sample Part Comparison If "1-C6-R" is part of a larger manufacturer string (like *GRM188...*), here is how it compares to standard parts: | Part Number Segment | Meaning | | :--- | :--- | | **1** | Series identifier | | **C** | Temperature Characteristic (e.g., 0±30ppm/°C) | | **6** | Voltage Code (e.g., 6.3V or 50V depending on brand) | | **R** | Packaging (Tape & Reel) or RoHS status | ---
