Key Technical Specifications Below are the estimated technical characteristics based on the standard naming conventions for this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | RF Inductor / Wideband Transformer | | **Inductance/Ratio** | Specific to "4RH2" tuning (4.2 nH or 1:4 Ratio) | | **Mounting Type** | Surface Mount (SMD) | | **Core Material** | Air Core or Ferrite (depending on frequency) | | **Tolerance** | ±5% to ±10% | | **Operating Temperature** | -40°C to +125°C | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the component's physical and electrical properties: * **48NAT**: The Series designation. Usually refers to a specific physical size (e.g., a compact footprint for high-density PCBs). * **4RH2**: The electrical value code. In RF components, this often dictates the winding ratio or the specific inductance value (e.g., 4.2). * **-R**: Indicates **RoHS Compliance** (Lead-free) and often implies **Tape and Reel** packaging for automated pick-and-place assembly. --- ### 3. Common Applications These parts are designed for high-performance signal integrity and are frequently found in: 1. **RF Circuits**: Used for impedance matching in antenna circuits. 2. **CATV/Broadband**: High-frequency transformers for cable television equipment. 3. **Wireless Infrastructure**: Base stations and satellite communication hardware. 4. **Signal Isolation**: Providing DC isolation while allowing high-frequency AC signals to pass. --- ### 4. Handling and Soldering * **Sensitivity**: As an SMD magnetic component, it is sensitive to excessive heat. Reflow profiles must follow J-STD-020 standards. * **Placement**: Due to its small size and air-core/ferrite nature, precise placement is required to avoid electromagnetic interference (EMI) with neighboring traces.
