The H82409S network transformer emerges as a standout component in industrial-grade Gigabit Ethernet ports, delivering exceptional value and reliability. Fully compatible with the classic Pulse H5084NL (matching performance and dimensions), it pairs seamlessly with Realtek’s RTL8111H-CG Gigabit PHY chip to create a cost-effective, high-performance Ethernet solution.

Designed for industrial rigor, the H82409S integrates advanced filtering and 1:1 voltage conversion coils to optimize signal isolation and noise immunity. Compliant with IEEE 802.3az energy efficiency standards, it ensures stable full-speed Gigabit transmission while minimizing power consumption. Its ultra-compact footprint (15.6×10.5×4.5mm) saves 20% PCB space versus traditional designs, ideal for space-constrained applications. Precision-engineered coupling coils enable accurate power/data separation, achieving tested transmission jitter below 0.5ns.

Engineered for harsh environments, it features a metal shield and TVS diode array for robust 15kV ESD protection. Engineers can directly upgrade existing H5084NL designs to enjoy identical performance with enhanced space savings—perfect for industrial controls, automation, and IoT devices demanding compact, reliable networking.
