The part number **1981045-1** refers to a specific electrical connector manufactured by **TE Connectivity (formerly Tyco Electronics)**. This component is primarily used in specialized power delivery and docking applications. --- ### 1. Part Identification and Specifications This part is a high-current, right-angle, board-to-board connector. It is often categorized under the **FORGE** or **Drawer Connector** product lines. | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity | | **Connector Type** | Power Socket (Right Angle) | | **Contact Gender** | Female (Socket) | | **Mounting Type** | Through-Hole, Right Angle | | **Number of Positions** | 2 Power Positions | | **Current Rating** | High Current (Typically up to 35A - 50A depending on trace) | | **Contact Material** | Copper Alloy | | **Contact Plating** | Gold (on mating area) | --- ### 2. Key Features * **Blind Mating:** These connectors are designed with built-in alignment features, allowing them to be plugged in even when the user cannot see the connection point (common in server racks). * **Robust Construction:** Designed for high-reliability environments where repeated mating cycles are expected. * **Low Contact Resistance:** Optimized for high-current delivery with minimal heat generation. * **Solder Tail:** Features pins designed for Wave Solder processes on a Printed Circuit Board (PCB). --- ### 3. Common Applications The 1981045-1 is typically found in industrial and computing infrastructure: 1. **Power Supplies:** Connecting a modular power supply unit (PSU) to a backplane. 2. **Server Racks:** Used in "hot-swappable" blade servers. 3. **Industrial Machinery:** Providing power to modular control units. 4. **Battery Storage Systems:** Connecting battery modules to a central management system. --- ### 4. Technical Drawing Overview If you are designing a PCB for this part, keep the following in mind: * **Footprint:** Ensure the hole diameters match the heavy-duty leads of the power pins. * **Orientation:** As a "Right Angle" connector, it sits flush against the edge of the board to allow horizontal mating. * **Thermal Relief:** Because this carries high current, ensure your PCB copper traces are wide enough to handle the amperage without overheating.
