The **708PS-2-R** is a specific electronic component, primarily known as a high-precision, low-profile **Resistor Network** or **Current Sense Resistor** package, often utilized in power management and industrial electronics. Below is a detailed breakdown of its technical aspects and specifications. --- ### 1. General Overview The "708" series generally refers to a specific package style, often a **Single In-line Package (SIP)** or a specialized surface-mount configuration depending on the manufacturer (commonly associated with brands like Bourns or specialized power resistor firms). The suffix `-R` typically denotes compliance with **RoHS** (Restriction of Hazardous Substances) standards. ### 2. Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Resistor Network / Discrete Resistor Array | | **Circuit Type** | Isolated or Bussed (Model dependent) | | **Resistance Range** | Varies (Commonly 10Ω to 1MΩ) | | **Power Rating** | Typically 125mW to 250mW per element | | **Operating Voltage** | 50V - 100V Max | | **Temperature Coefficient** | ±100 ppm/°C or ±250 ppm/°C | | **Compliance** | RoHS Lead-Free | --- ### 3. Key Electronic Characteristics * **Miniaturization:** The "708" designation often implies a specific height (low profile), making it ideal for high-density circuit boards where vertical space is limited. * **Precision:** These parts are engineered for stability. The laser-trimmed resistive elements ensure that the resistance value remains constant even under thermal stress. * **Integration:** By combining multiple resistors into one "708" package, manufacturers reduce the component count on a PCB, which simplifies the assembly process and improves reliability. ### 4. Common Applications 1. **Pull-up/Pull-down Networks:** Used in digital logic circuits to ensure pins stay at a specific voltage level. 2. **Voltage Dividers:** Creating precise reference voltages for analog-to-digital converters (ADCs). 3. **Current Limiting:** Protecting LEDs or sensitive transistor bases from overcurrent. 4. **Termination:** Used in transmission lines to prevent signal reflections in high-speed data buses. --- ### 5. Part Number Breakdown (Typical) While naming conventions vary by brand, a typical breakdown looks like this: * **708:** Series identifier (Package size/Physical style). * **PS:** Circuit configuration (e.g., Parallel, Serial, or Isolated). * **2:** Number of resistors or pin configuration. * **R:** RoHS compliant (Lead-free).
