Based on your query, it appears you are referring to the **FTS-16-R**, which is a high-performance **Micro-Stripline Header/Socket system** manufactured by **Samtec**. Below is a detailed breakdown of its electronic specifications, physical characteristics, and typical applications. --- ## 1. Technical Specifications The FTS series is designed for surface-mount (SMT) applications where a low profile and high density are required. | Feature | Specification | | :--- | :--- | | **Pitch** | .050" (1.27 mm) | | **Terminal Material** | Phosphor Bronze | | **Plating** | Au (Gold) or Sn (Tin) over 50 µ" (1.27 µm) Ni | | **Operating Temp Range** | -55 °C to +125 °C | | **Current Rating** | 3.4 A per pin (2 pins powered) | | **Voltage Rating** | 350 VAC | | **RoHS Compliant** | Yes | --- ## 2. Part Number Breakdown: FTS-16-R While specific suffixes can vary, here is the standard decoding for this part type: * **FTS:** Series Prefix (Low Profile Terminal Strip). * **16:** Typically denotes the number of positions per row (or total pins depending on configuration). * **R:** Usually indicates the **Packaging** (e.g., Tape and Reel) or a specific **Orientation** (Right Angle). *Note: In Samtec's standard FTS nomenclature, "-TR" is Tape & Reel, while "-S" or "-D" defines rows.* --- ## 3. Key Electronic Characteristics ### Signal Integrity Because of the small 1.27mm pitch and low profile, these connectors are excellent for high-speed signal integrity. They minimize inductance compared to standard 2.54mm (0.100") headers. ### Contact Resistance The use of phosphor bronze with gold plating ensures a very low contact resistance (typically < 10 mΩ), which is critical for sensitive logic-level signals. ### Durability These parts are rated for approximately 100 mating cycles when using gold plating, making them suitable for internal board-to-board connections that are not frequently unplugged. --- ## 4. Common Applications * **Embedded Systems:** Connecting "daughter" boards to a main motherboard. * **Industrial Controllers:** Compact PLC modules. * **Telecommunications:** High-density routing in switches or routers. * **Handheld Devices:** Due to the ultra-low profile (1.27mm height). --- ## 5. Footprint Example (CAD/EDA) When designing a PCB for the FTS-16, the SMT pads must be precisely aligned. Below is a conceptual representation of the pad layout: ```markdown (Row A) [ ] [ ] [ ] [ ] (1.27mm centers) (Row B) [ ] [ ] [ ] [ ] <-------------> Pitch Length ```
