The **RG2-204N-R15** is a high-precision, metal film chip resistor. These components are typically used in circuits where stability, low noise, and tight tolerances are critical. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The part number follows a specific nomenclature used by manufacturers (commonly **Susumu**). | Feature | Specification | Description | | :--- | :--- | :--- | | **Type** | Metal Film Resistor | Provides better stability than carbon film. | | **Resistance Value** | 0.15 $\Omega$ (R15) | Low resistance value, often used for current sensing. | | **Tolerance** | $\pm 0.5\%$ (N) | High precision for accurate circuit performance. | | **Package Size** | 0805 (Metric 2012) | Standard surface mount device (SMD) size. | | **Series** | RG Series | Known for high reliability and ultra-low noise. | --- ### 2. Key Electronic Characteristics #### A. Thin Film Technology Unlike standard thick film resistors, the RG series uses thin-film technology. This results in: * **Low Noise:** Excellent signal-to-noise ratio, making it ideal for audio and measurement equipment. * **Long-term Stability:** Minimal resistance drift over thousands of hours of operation. #### B. Temperature Coefficient of Resistance (TCR) This part usually features a very low TCR (typically $\pm 25ppm/^\circ C$ or lower). This means the resistance value stays nearly constant even as the temperature of the circuit changes. #### C. Power Rating For a 0805 package in the RG series, the power rating is typically around **0.125W (1/8W)** to **0.25W**, depending on the specific sub-rating of the manufacturer. --- ### 3. Common Applications Due to its low resistance (0.15 $\Omega$) and high precision, this part is frequently found in: 1. **Current Sensing:** Measuring the voltage drop across the resistor to determine current flow in power management circuits. 2. **Operational Amplifiers:** Used in feedback loops where precision is mandatory. 3. **Automotive Electronics:** Used in ECUs and sensors due to its reliability under harsh conditions. 4. **Medical Equipment:** High-precision measurement devices. --- ### 4.
