TLA-7T201LF-T Datasheet, PDF (21/34 Pages) TDK Electronics – Pulse transformers

(20/33)
TLA-7T201LF(-T) ISO8802.3(IEEE802.3) 10/100/1000BASE-T
FEATURES
• Product conforming to RoHS directive.
• Can be mounted with lead-free solder (260°C max.).
• 24-pin SMD package(1.27mm=50mil pin pitch).
• Because it is low profile design of 2.2mm max., space saving is
possible and is suitable for notebook PC.
• Excellent common mode noise suppression.
• Inductance is 350μH or greater (f=100kHz, DC bias=8mA).
• Using the high-quality and wide-band ferrite cores for LAN.
• Packaging specification is taping and bulk(TLA-7T201LF-T:
Tape and reel, TLA-7T201LF: Bulk).

• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
• All specifications are subject to change without notice.
