ZE2549 Series

Common mode choke for 10BASE-T1 Applications

The ZE2549 is a common mode choke designed for Single Pair Ethernet (SPE) networks, providing common mode noise suppression and EMI reduction in 10BASE-T1L applications. It supports data only transmission as well as with Power over Data Line (PoDL) for transmitting both data and power over a single twisted pair cable. The part is compliant with the IEEE 802.3cg standard. It works with 10BASE-T1L isolation transformers and power injection chokes as a complete solution for 10Base-T1L applications, including industrial automation, building automation, IoT, and others, where low-cost, long-range Ethernet is essential.

メモ

When ordering, please specify packaging code: e.g. ZE2549-474LC
Inductance is for each winding, measured at 100 kHz, 0.1 V.
Irms current is the current when applied to both windings in series that causes the specified temperature rise from room temperature.
DCR is specified per winding.
1500 VDC (1000 Vrms), one minute isolation (hipot) between windings.
