The **2223-R** (often associated with the Bourns series or specific resistor networks) typically refers to a high-voltage, thick-film **ChIP Resistor** or a specific **Resistor Network** component. In the context of passive electronics, this series is designed for applications requiring stability under high voltage or high-frequency conditions. --- ### 1. Key Technical Specifications The following table outlines the general characteristics of the 2223-R series components: | Feature | Description | | :--- | :--- | | **Component Type** | Thick Film Chip Resistor / Network | | **Resistance Range** | Typically 10 $\Omega$ to 20 M$\Omega$ | | **Tolerance** | $\pm 1\%$ to $\pm 5\%$ | | **Power Rating** | 0.25W to 1W (Size dependent) | | **Operating Temperature** | -55°C to +155°C | | **Suffix "-R"** | Denotes RoHS Compliance (Lead-Free) | --- ### 2. Physical Construction The "2223" designation often refers to the **EIA Package Size**, which measures approximately **0.22 x 0.23 inches** (roughly 5.6 x 5.8 mm). - **Substrate:** Alumina ceramic for heat dissipation. - **Resistive Element:** Ruthenium oxide (RuO2) thick film. - **Terminations:** Tin (Sn) over Nickel (Ni) barrier to prevent leaching during soldering. - **Coating:** Epoxy or glass encapsulation for environmental protection. --- ### 3. Common Applications These parts are engineered for reliability in demanding circuits: 1. **Power Supplies:** Used in feedback loops and voltage dividers. 2. **Medical Electronics:** High-impedance sensors and imaging equipment. 3. **Industrial Controls:** Motor drives and PLC input protection. 4. **Consumer Electronics:** Power adapters and high-wattage LED drivers. --- ### 4. Part Number Breakdown (Typical Example) When reading a full part number (e.g., `CR2223-J-103-R`), the segments usually mean: - **CR:** Chip Resistor. - **2223:** Physical dimensions (Package size). - **J:** Tolerance code (J = 5%, F = 1%). - **103:** Resistance value ($10 \times 10^3 = 10k \Omega$). - **R:** RoHS Compliant.
