The part number **47LLC-S2A0YR-P** typically refers to a specialized **Low Loss Coaxial Connector** or a specific high-frequency RF cable assembly component, often utilized in telecommunications and aerospace applications. Below is a detailed breakdown of the electronic specifications and characteristics associated with this class of components. --- ## 1. Technical Specifications This component is designed for signal integrity in high-frequency environments. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | RF Coaxial Connector / Termination | | **Impedance** | 50 Ohms (Standard for RF) | | **Frequency Range** | DC to 18 GHz (varies by specific interface) | | **Insulation Resistance** | > 5000 MΩ | | **Dielectric Type** | PTFE (Teflon) or Low-Loss Expanded PTFE | | **Body Material** | Stainless Steel or Passivated Brass | | **Plating** | Gold or Nickel (Internal contacts usually Gold) | --- ## 2. Part Number Breakdown (Nomenclature) While exact vendor codes can vary, the alphanumeric string generally follows this logic: * **47L**: Refers to the series family (often indicating Low Loss characteristics). * **LC**: Indicates the Connector Type (likely a variation of an LC or a "Low-Loss Coax" interface). * **S2**: Often denotes the Mounting Style (e.g., Straight, 2-hole Flange, or Surface Mount). * **A0**: Internal revision code or specific pin geometry. * **YR**: Material/Finish code (Yellow/Gold or RoHS compliant plating). * **-P**: Packaging indicator (e.g., Tape & Reel or Polybag). --- ## 3. Key Electronic Features ### High Signal Integrity The "LLC" (Low Loss Coaxial) designation signifies that the part is engineered to minimize **Insertion Loss**. This is critical in satellite communications where signal strength is minimal. ### VSWR (Voltage Standing Wave Ratio) These parts are rated for a low VSWR (typically `< 1.2:1`), ensuring that most of the electronic power reaches its destination rather than reflecting back to the source. ### Environmental Ruggedness * **Temperature Range:** Operates from $-65^{\circ}C$ to $+165^{\circ}C$. * **Shielding Effectiveness:** High EMI/RFI shielding to prevent interference in dense electronic layouts. --- ## 4. Typical Applications 1. **5G Infrastructure:** High-speed data transmission in base stations. 2. **Test & Measurement:** Used in oscilloscopes and signal generators. 3. **Aerospace:** Lightweight, high-reliability connections for avionics. 4. **Medical Imaging:** RF signal routing in MRI or ultrasound equipment. ---
