LAN Discrete Transformer Modules

Pulse Electronics LAN Discrete Transformer Modules are optimized for all major LAN transceivers. These modules provide electrical circuit isolation that meets IEEE 802.3 standards while maintaining the signal integrity needed for the most demanding applications. Pulse Electronics LAN Discrete Transformer Modules feature a peak reflow temperature rating of +245°C. Other features include 1kHz to 100MHz frequency range, 1Ω impedance, 350µH inductance, and 1.5kV isolation voltage.
