Product Introduction
QITDA QR2120A‑UPB722EF is a 100Base‑T RJ45 modular jack with integrated magnetics transformer and EMI filter. 10P8C configuration, DIP through‑hole type with green‑yellow dual‑color LED indicators. Metal shield housing supports laser marking. Built‑in magnetic module provides signal isolation and noise suppression, removing external magnetics requirement and simplifying PCB layout. Widely used for NVR recorder, 100M switch, router, industrial mainboard and IOT gateway. Custom solutions are available for bulk orders.
Key Features
Integrated 100M Transformer & EMI Filter Magnetics
Built‑in magnetic transformer for signal isolation and common‑mode noise suppression, improve differential signal quality and reduce EMI interference. No extra magnetic components needed, save PCB layout space.
DIP Through‑hole Soldering Design
Standard DIP pin layout, compatible with wave soldering process. Stable soldering performance for mass‑volume manufacturing.
Dual‑color LED Status Indicator
Green‑yellow LED shows link and data‑activity status for convenient debugging. LED light color can be customized.
Metal Shield Shell with Laser Marking Support
Full metal housing blocks external electromagnetic interference. Top surface supports laser engraving for part number or brand logo for traceability.
Gold‑plated Copper Contacts
Copper contact pins with optional gold plating (3U‑30U). Anti‑oxidation, durable insertion cycles and low signal loss for stable network connection.
