The **RG1-103S-R15** is a high-precision, thin-film chip resistor manufactured by **Susumu**. It belongs to the **RG Series**, which is renowned in the electronics industry for its high reliability, low noise, and excellent stability under harsh environmental conditions. --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of the RG1-103S-R15: | Parameter | Value / Specification | | :--- | :--- | | **Resistance** | 10 kΩ (103) | | **Tolerance** | ±0.05% (S) | | **Temperature Coefficient (TCR)** | ±5 ppm/°C (R) | | **Power Rating** | 0.063W (1/16W) | | **Case Size (Inch/Metric)** | 0402 / 1005 | | **Max Operating Voltage** | 25V | | **Operating Temperature** | -55°C to +155°C | | **Technology** | Thin Film (Metal Film) | --- ### ## Key Features & Construction 1. **Thin Film Technology:** Unlike standard thick film resistors, the RG series uses a sputtered metal film on a ceramic substrate. This results in much lower electronic noise and better linearity. 2. **Long-Term Stability:** The "RG" series features a unique inorganic passivated structure (glass coating), making it highly resistant to moisture, sulfur, and heat cycles. It typically exhibits less than 0.1% drift after 10,000 hours. 3. **High Precision:** With a tolerance of **±0.05%**, this component is intended for circuits where exact resistance values are critical to the system's performance. 4. **Low TCR:** The **±5 ppm/°C** rating ensures that the resistance remains nearly constant even as the ambient temperature or internal heat changes. --- ### ## Part Number Breakdown The nomenclature can be decoded as follows: | Code | Meaning | | :--- | :--- | | **RG** | Series Name (High reliability thin film) | | **1** | Case Size (1005 / 0402) | | **103** | Resistance Value (10 + three zeros = 10,000 Ω) | | **S** | Resistance Tolerance (±0.05%) | | **R** | Temperature Coefficient (±5 ppm/°C) | | **15** | Packaging Code (usually refers to tape/reel quantity) | --- ### ## Typical Applications Due to its high accuracy and stability, the RG1-103S-R15 is commonly used in: * **Medical Equipment:** Precision imaging and monitoring sensors. * **Automotive Electronics:** Engine control units (ECU) and ADAS systems. * **Test and Measurement:** Multimeters, oscilloscopes, and signal generators. * **Industrial Automation:** High-end PLC analog input modules. * **Telecommunications:** Base station power management and signal conditioning.
