The part number **M8YV-F44-R/F** typically refers to a high-density, high-performance connector, often associated with **JAE (Japan Aviation Electronics Industry)** or similar manufacturers specializing in board-to-board or board-to-cable interfaces. Below is a detailed breakdown of the electronic and structural characteristics of this component. --- ### 1. General Specifications This part is designed for applications requiring a large number of signal paths in a compact footprint. It is commonly used in industrial automation, medical equipment, and telecommunications. | Feature | Specification Details | | :--- | :--- | | **Connector Type** | High-density Board-to-Board or Interface Connector | | **Pin Count** | 44 Pins (typically arranged in multiple rows) | | **Gender** | Female (Receptacle) | | **Mounting Style** | Right Angle (indicated by 'R') / Surface Mount (SMT) | | **Plating** | Gold (Au) flash over Nickel (Ni) for high conductivity and oxidation resistance | | **Operating Temp** | -40°C to +85°C (standard industrial grade) | --- ### 2. Key Electronic Parameters The electrical integrity of the M8YV series is optimized for low-voltage signal transmission. * **Current Rating:** Typically 0.5A to 1.0A per contact (depending on temperature rise). * **Voltage Rating:** 100V AC/DC. * **Contact Resistance:** Maximum 40mΩ to 50mΩ (initial). * **Insulation Resistance:** Minimum 1000MΩ (at 500V DC). * **Dielectric Withstanding Voltage:** 500V AC for 1 minute without breakdown or flashover. --- ### 3. Mechanical & Material Construction The "F44" designation indicates a 44-position layout, while the suffixing describes the orientation and lead-free status. * **Housing:** High-temperature Thermoplastic (UL94V-0 rated), usually LCP (Liquid Crystal Polymer) to withstand lead-free reflow soldering. * **Contacts:** Copper alloy (e.g., Phosphor Bronze) for durability and elasticity. * **Mating Cycles:** Designed for approximately 50 to 100 mating cycles. * **R/F Designation:** * **R:** Right Angle orientation (connector sits 90 degrees to the PCB). * **F:** Frequently denotes "Lead-Free" (RoHS Compliant) or a specific Flange/Fixing style for mechanical stability. --- ### 4. Common Applications Due to its high pin density and reliability, the M8YV-F44-R/F is found in: 1. **Industrial Controllers:** Connecting daughterboards to backplanes. 2. **Imaging Systems:** Transmitting sensor data in medical scanners. 3. **Networking Hardware:** Internal high-speed signal routing in routers/switches. ---
