The **TS-75-R** refers to a specific series of miniature, high-frequency, surface-mount (SMD) coaxial connectors, often associated with the **Hirose U.FL** or similar micro-coaxial standards used in RF (Radio Frequency) applications. These parts are critical for modern wireless communication devices. --- ### 1. Technical Specifications The "TS" series typically follows these electrical and mechanical parameters: | Feature | Specification | | :--- | :--- | | **Impedance** | 50 Ohms (Standard for RF) | | **Frequency Range** | DC to 6 GHz | | **V.S.W.R.** | 1.3 Max (at 0-3 GHz) / 1.5 Max (at 3-6 GHz) | | **Contact Resistance** | 20 mΩ Max | | **Withstanding Voltage** | 200V AC / 1 minute | | **Operating Temp** | -40°C to +85°C | ### 2. Physical Components The TS-75-R is composed of three primary material sections: 1. **Housing/Insulator:** Usually made of High-Temperature Thermoplastic (LCP - Liquid Crystal Polymer) to withstand reflow soldering temperatures. 2. **Center Contact:** Gold-plated Phosphor Bronze or Brass for high conductivity and oxidation resistance. 3. **Outer Shell (Ground):** Silver-plated or Gold-plated Phosphor Bronze to ensure high-quality shielding and grounding. --- ### 3. Key Applications Because of its small footprint and reliable high-frequency performance, this part is used in: * **Wireless Modules:** Wi-Fi, Bluetooth, and ZigBee modules. * **Mobile Devices:** Smartphones, tablets, and wearable tech for internal antenna connections. * **IoT Hardware:** GPS trackers and smart home sensors. * **Embedded Systems:** Connecting external antennas to internal PCB traces. ### 4. Mounting and Usage * **SMD Reflow:** These parts are designed for automated SMT (Surface Mount Technology) assembly lines. * **Mating:** They are designed to mate with ultra-fine coaxial cable assemblies (e.g., 0.81mm or 1.13mm diameter cables). * **Durability:** Being "miniature," they are typically rated for **30 to 50 mating cycles**. They are not intended for frequent plugging/unplugging by the end-user. --- ### 5. Part Number Breakdown (Typical) While naming conventions vary by manufacturer (e.g., Top-Link, Hirose, or IPEX equivalents), the code usually signifies: * **TS:** Series Designator. * **75:** Specific height or profile series (e.g., 1.25mm or 1.5mm mated height). * **R:** Packaging format, usually indicating **Reel** for automated pick-and-place machines.
