H6400NL H6400NLT Quad Port 1000BASE-T Discrete Magnetic Transformers
H6400NL/H6400NLT Quad Port 1000BASE-T Ethernet Transformer
Product Overview:
The H6400NL and H6400NLT are high-performance Quad Port 1000BASE-T Ethernet Transformers designed for advanced networking applications requiring superior signal integrity and reliable power delivery. These LAN Transformers feature an open frame construction in a BGA (Bump Grid Array) package, optimized for 1000BASE-T data transmission. Engineered to comply with IEEE 802.3 standards for Gigabit Ethernet applications fully, the H6400NL/H6400NLT series delivers exceptional electromagnetic performance with carefully controlled insertion loss, return loss, and crosstalk parameters across a wide frequency range. These transformers provide excellent common-mode rejection and maintain signal quality even in electrically noisy environments, making them ideal for data centers, networking equipment, and industrial Ethernet applications.
