The **RG2-504N-R15** is a high-precision, thin-film chip resistor array (network) manufactured by **Susumu**. These components are designed for high-density circuits where stability, low noise, and precise resistance ratios are critical. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Resistance Value** | 500k $\Omega$ (504) | | **Tolerance** | ±0.1% (N) | | **Temperature Coefficient (TCR)** | ±25 ppm/°C | | **Power Rating** | 0.063W (1/16W) per element | | **Package Style** | 0805 (2012 Metric) - 2 Elements | | **Operating Temp Range** | -55°C to +125°C | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps identify the specific characteristics of this electronic part: * **RG**: Series code for Susumu’s High Precision Thin Film Chip Resistors. * **2**: Number of resistive elements (2 resistors in one package). * **504**: Resistance code ($50 \times 10^4 = 500,000 \Omega$ or 500k$\Omega$). * **N**: Resistance tolerance code (±0.1%). * **R15**: Packaging or specific internal design revision (often refers to tape and reel specifications). --- ### 3. Core Features and Construction #### Thin Film Technology Unlike standard thick-film resistors (which use a paste), thin-film resistors use a sputtered metal film on a ceramic substrate. This results in: * **Lower Noise:** Reduced current noise for sensitive analog signals. * **Tight Tolerance:** Extremely precise resistance values. * **Stability:** Long-term resistance drift is minimal compared to standard components. #### Network Configuration As an **array**, this part contains two resistors in a single SMT (Surface Mount Technology) package. This is highly beneficial for: * **Thermal Tracking:** Because both resistors are on the same substrate, they heat up and cool down at the same rate, maintaining a constant resistance ratio. * **Space Saving:** Occupies less PCB real estate than two individual 0402 or 0603 resistors. --- ### 4. Common Applications 1. **Voltage Dividers:** Used where a precise ratio between two voltages is required. 2. **Operational Amplifiers:** Providing feedback loops or gain setting where precision is paramount. 3. **Instrumentation:** Medical or industrial measurement devices that require low thermal drift. 4. **Audio Equipment:** High-end audio signal paths to minimize distortion and noise. ---
