## Overview of the PL71-R-PC The **PL71-R-PC** is a high-frequency coaxial connector primarily manufactured by **Hirose Electric**. It is part of the PL71 series, which is specifically designed for high-density packaging and high-speed signal transmission, commonly used in the broadcasting and telecommunications industries. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | BNC Coaxial (Micro-miniature) | | **Gender** | Female (Jack) | | **Mounting Type** | PCB Through-Hole (Right Angle) | | **Impedance** | 75 Ohms (Standard for Video/Broadcast) | | **Frequency Range** | Up to 3 GHz | | **Termination Method** | Solder | --- ### 2. Physical and Material Characteristics * **Right Angle Design:** The "R" in the part number denotes a **Right Angle** configuration. This is ideal for space-constrained PCB layouts where the cable needs to connect parallel to the board. * **75 Ohm Impedance:** Specifically engineered to match the impedance requirements of high-definition video signals (HD-SDI) and telecommunications, minimizing signal reflection and loss. * **Compact Size:** The PL71 series is significantly smaller than standard BNC connectors, allowing for a higher density of ports on a single interface panel. * **Material Construction:** * **Body:** Usually brass or zinc alloy with nickel plating for durability and corrosion resistance. * **Contact:** Gold-plated phosphor bronze or brass to ensure high conductivity and reliable mating cycles. --- ### 3. Common Applications The PL71-R-PC is widely used in professional electronic equipment where high-frequency signal integrity is critical: 1. **Broadcasting Equipment:** Used in switchers, routers, and cameras for HD-SDI video transmission. 2. **Telecommunications:** Integration into digital cross-connect systems and transmission devices. 3. **Medical Imaging:** High-resolution video output for medical monitors and diagnostic tools. 4. **Test and Measurement:** High-speed data acquisition boards. --- ### 4. Mounting Layout (General Reference) When designing a PCB for this part, the footprint typically requires a specific arrangement of the signal pin and ground legs: ```text [PCB Footprint Concept] ○ (Ground) | ○ ---- ● ---- ○ (GND) (Signal) (GND) | ○ (Ground) ``` *Note: Always consult the official Hirose datasheet for exact dimensions and hole diameters before PCB fabrication.* ---
