The term **1-13-R** typically refers to a specific part numbering convention used by electronic component manufacturers (most notably **Xicon** or **Eagle Plastic Devices**) to identify physical specifications of hardware or passive components. In most contexts involving electronics distribution, this part number corresponds to **Hardware Spacers, Standoffs, or Control Knobs.** --- ### 1. Component Specifications Based on common industry catalogs (like Mouser or Digi-Key), here are the technical details for the "1-13-R" series: | Property | Description | | :--- | :--- | | **Category** | Hardware / Accessories | | **Type** | Round Spacer / Standoff | | **Material** | Usually Aluminum or Nylon (depending on prefix) | | **Inner Diameter** | Clearance for #4 or #6 screws (typically 0.125" to 0.140") | | **Outer Diameter** | Approximately 1/4" (0.250") | | **Length** | "13" often denotes the length in increments (e.g., 13/32" or 13mm) | | **RoHS Status** | The **-R** suffix strictly indicates **RoHS Compliance** | ### 2. Decoding the Part Number Manufacturers use alphanumeric codes to condense specifications into a single string. Here is how to break down **1-13-R**: 1. **"1" (Series Prefix):** Identifies the material and basic shape (e.g., Round Aluminum). 2. **"13" (Size/Length Code):** This is the dimensional variable. In the hardware world, this identifies how tall the spacer is or the thread pitch. 3. **"-R" (Compliance):** Standing for "RoHS" (Restriction of Hazardous Substances). This ensures the part does not contain lead, mercury, or cadmium. ### 3. Common Applications These parts are used in the mechanical assembly of electronic devices: * **PCB Mounting:** To hold a Printed Circuit Board away from a metal chassis to prevent short circuits. * **Stacking:** To stack multiple boards on top of one another. * **Thermal Isolation:** Providing air gap spacing for heat dissipation. --- ### Alternative: Resistor Networks In some legacy schematics, "1-13-R" might refer to a specific pin configuration on a **SIP (Single In-line Package) Resistor Network**. ```text Pin 1: Common Pins 2-13: Individual Resistors R: Resistance Value (e.g., 10k) ``` **Note:** If your "1-13-R" is a specific component like a resistor or capacitor from a specific brand (e.g., Vishay or Murata), please provide the manufacturer's name for a more precise datasheet breakdown.
