The **RG2-304N-R15** is a high-precision, thick-film chip resistor array (network) manufactured by companies like Susumu. These components are designed to provide multiple resistors in a single package with high reliability and stability. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Parameter | Value/Description | | :--- | :--- | | **Resistor Type** | Thick Film Chip Resistor Network | | **Resistance Value** | 300k $\Omega$ (indicated by "304") | | **Tolerance** | $\pm$ 0.5% (High Precision) | | **Circuit Type** | Isolated (Individual resistors) | | **Number of Elements** | 4 Resistors | | **Package Style** | Convex Terminal (RG Series) | | **Operating Temp** | -55°C to +125°C | --- ## 2. Key Electronic Components & Features ### A. Internal Circuit Configuration The "N" in the part number typically signifies the circuit configuration. For this model: * **Isolated Design:** Each of the 4 resistors is electrically independent. There is no common bus or shared ground within the package. * **Pin Count:** 8 pins (2 pins per resistor). ### B. Precision and Stability Unlike standard general-purpose resistors, the RG series focuses on: * **Low Noise:** Designed to minimize current noise, making it suitable for sensitive analog circuits. * **TCR (Temperature Coefficient of Resistance):** Usually features a low TCR (e.g., ±25ppm/°C or ±50ppm/°C), meaning the resistance changes very little as the temperature fluctuates. ### C. Construction Material * **Substrate:** High-purity Alumina (Ceramic). * **Resistive Element:** Metal glaze/Thick film. * **Terminations:** Lead-free (RoHS compliant) with a nickel barrier and tin plating for excellent solderability. --- ## 3. Common Applications Due to its high density and precision, the RG2-304N-R15 is used in: 1. **Voltage Dividers:** Where multiple resistors must have matched characteristics. 2. **Pull-up/Pull-down Arrays:** In high-density PCB layouts for digital logic. 3. **Industrial Controls:** Measurement equipment requiring long-term stability. 4. **Telecom Equipment:** Signal conditioning and impedance matching. --- ## 4.
