The part number **888-3-R330F** typically refers to a **thick film chip resistor network**, often manufactured by companies like **Bourns** or **CTS Corporation**. These components are used to simplify PCB layouts by integrating multiple resistors into a single package. --- ### 1. Key Technical Specifications Based on standard industry naming conventions for this series, here is a breakdown of the technical attributes: | Parameter | Specification | | :--- | :--- | | **Resistor Type** | Thick Film Chip Resistor Network | | **Resistance Value** | 33 Ohms ($\Omega$) | | **Tolerance** | $\pm 1\%$ (Indicated by the "F" suffix) | | **Circuit Configuration** | Isolated or Bussed (Commonly "Isolated" for 8-pin models) | | **Package Type** | DIP (Dual In-line Package) or SIP (Single In-line Package) | | **Number of Pins** | 8 Pins (Indicated by the "888" or "8" prefix) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the exact functionality: * **888**: Usually designates the series or the physical package style (often an 8-pin configuration). * **3**: Represents the internal circuit configuration. * *Type 3* usually indicates **Isolated Resistors**, where each resistor in the package is independent of the others. * **R330**: The resistance code. * The "R" acts as a decimal point, or the "330" follows the 3-digit code rule (33 + 0 zeros = 33 $\Omega$). * **F**: The tolerance code. * **F = $\pm 1\%$** (Precision grade). --- ### 3. Internal Circuitry In a "Type 3" (Isolated) configuration with 8 pins, the package contains **4 independent resistors**. ```text Pin 1 ----[ R1 ]---- Pin 8 Pin 2 ----[ R2 ]---- Pin 7 Pin 3 ----[ R3 ]---- Pin 6 Pin 4 ----[ R4 ]---- Pin 5 ``` --- ### 4. Common Applications * **Line Termination:** Used in high-speed data lines to prevent signal reflection. * **LED Current Limiting:** Providing uniform resistance for multiple LED indicators. * **Pull-up/Pull-down:** Maintaining logic levels in digital circuits (Microcontrollers/FPGAs). * **Space Saving:** Reducing the component count on a PCB compared to using individual 0805 or 0603 resistors. ---
