HY981141A General Specifications

Overview

The HY981141A Single Port RJ45 + USB Connector with Integrated Magnetics and LED is designed for 10/100/1000Base-T NIC applications, providing reliable network connectivity in a compact form factor. This connector integrates magnetics for signal integrity, EMI suppression, and isolation, while the LED indicators allow easy monitoring of network status.

Key highlights:

• Supports Gigabit Ethernet (10/100/1000Base-T) for high-speed data transmission.
• Combines RJ45 and USB ports in a single package for versatile connectivity.
• Integrated magnetics reduce board space requirements and simplify system design.
• LED indicators (Green, Orange, Yellow) provide clear network activity and link status feedback.
• RoHS compliant and UL recognized, ensuring environmental safety and reliable performance.

This connector is ideal for network interface cards (NICs), embedded systems, and industrial applications requiring robust, space-saving connectivity with clear status indication.
