The term **"007-R"** in electronics typically refers to one of two things: a specific **surface-mount resistor** marking or a **model suffix** for connectors and mechanical components. Below is a breakdown of what these electronic parts represent based on standard industry coding. --- ### 1. The "007" Resistor Code (EIA-96 Standard) In the world of precision surface-mount technology (SMT), codes are often used instead of direct values to save space. According to the **EIA-96 marking scheme**: | Component | Code | Interpretation | | :--- | :--- | :--- | | **Value Code** | 00 | Represents the base value **100** | | **Multiplier** | 7 | Represents $10^7$ | | **Resistance** | **007** | **1,000,000,000 $\Omega$ (1 Gigaohm)** | *Note: The suffix **-R** usually denotes the packaging type (Tape & Reel) or compliance with RoHS standards.* --- ### 2. Common Components with "007-R" Suffix Many manufacturers use "007-R" as a suffix for specific series. Here are the most common occurrences: #### A. Modular Jacks and Connectors Many RJ45 and RJ11 connectors (like those from manufacturers like *Stewart Connector* or *Bel Fuse*) use this numbering. * **007:** Often refers to the specific housing style or gold plating thickness. * **-R:** Generally signifies **RoHS Compliance** (Restriction of Hazardous Substances). #### B. Power Supplies and Converters In some DC-DC converter series: * **-R:** Stands for **Remote On/Off** capability or **Reverse Polarity** protection depending on the datasheet. #### C. Fuses and Protection In certain fuse series (like those from *Littlefuse* or *Bussmann*): * **-R:** Frequently stands for **RoHS Lead-Free** version of a legacy part. --- ### 3. Summary of Characteristics If you are looking at a physical part labeled "007-R", here is how to identify it: | Feature | Description | | :--- | :--- | | **Material** | Usually Ceramic (Resistors) or Thermoplastic (Connectors) | | **Mounting** | Typically **SMD** (Surface Mount Device) or **TH** (Through-Hole) | | **Compliance** | Almost always implies **RoHS compliant** | | **Packaging** | Often indicates **Tape and Reel** for automated assembly | --- **Recommendation:** To identify the exact part, please check the **Manufacturer's Logo** or the **Package Type** (e.g., 0603, 0805, or a plastic housing).
