The **FJT-96-R/Q** refers to a specific series of **F-Type Coaxial Connector PCB Jacks**. These are commonly used in telecommunications, cable television (CATV), and RF signal processing equipment to bridge physical coaxial cables to a printed circuit board. --- ## 1. Technical Specifications Below are the typical electrical and mechanical characteristics for the FJT-96-R/Q series: | Parameter | Specification | | :--- | :--- | | **Connector Type** | F-Type (Female) | | **Mounting Type** | Through-Hole (Right-Angle / 90°) | | **Impedance** | 75 Ohms (Nominal) | | **Frequency Range** | 0 - 2.5 GHz / 3 GHz | | **Contact Resistance** | ≤ 20 mΩ | | **Insulation Resistance** | ≥ 500 MΩ | | **Voltage Rating** | 500V AC | --- ## 2. Part Suffix Breakdown The letters following the base part number usually indicate specific physical configurations: ### FJT-96-R * **"R" (Right Angle):** This indicates that the connector pins are bent at a 90-degree angle. When mounted, the cable plugs into the connector parallel to the PCB surface. * **Mounting:** Usually features two or more grounding legs (tabs) to provide structural stability and EMI shielding. ### FJT-96-Q * **"Q" (Quick/Special Mount):** In many RF component catalogs, "Q" signifies a specific height profile or a "Quick-Connect" threadless design, though in the FJT series, it often refers to a specific **Pin Length** or a **Body Material** variation (such as Zinc Alloy vs. Brass). --- ## 3. Physical Components The FJT-96 series is composed of four primary electronic/mechanical parts: 1. **Outer Shell (Body):** Usually made of Nickel-plated Zinc or Brass. It acts as the ground return and provides shielding against electromagnetic interference (EMI). 2. **Center Contact:** Typically Phosphor Bronze with Gold or Tin plating. This transmits the actual high-frequency signal. 3. **Insulator (Dielectric):** Often Polypropylene (PP) or Polyethylene (PE). This maintains the 75-ohm impedance by providing a specific distance between the center pin and the ground shell. 4. **Mounting Leads:** The "R" configuration uses through-hole pins designed to be wave-soldered or hand-soldered to the PCB. --- ## 4. Common Applications * **Set-Top Boxes (STB):** The primary input for satellite or cable signals. * **Cable Modems:** Used for high-speed DOCSIS data transmission. * **Signal Splitters/Amplifiers:** Distribution points within a building's RF network. * **Headend Equipment:** Professional-grade video processing hardware.
