TMQ Series • 10Base-T Quad SMD Transformer Modules
Features
• Low profile (5.8mm) and light weight (4.0 g) 10Base T Quad
modules facilitate pick and place compatability and speed
of placement
• Four port modules meet requirements of IEEE 802.3
• Consistent and reliable coplanarity
• Manufactured in an ISO-9001:2000, TS-16949:2002
and ISO-14001:2004 certified Talema facility
• Fully RoHS compliant and meets lead free reflow
level J-STD-020C
Quality and consistency is guaranteed through 100% testing
of the specified parameters for primary inductance, leakage
inductance, turns ratio, DC resistance and interwinding
capacitance.This ensures that the return loss and pulse
wave shape requirements can be fully maintained.
Additionally, all parts are tested for 1500V minimum isolation.

Applications
Talema 10BaseT Quad transformer modules contain
transmit and receive isolation transformers to maintain
consistant wave shape and suppression of common mode
noise while providing equipment isolation per IEEE 802.3.
High impedance common mode quad chokes for additional
EMI suppression have been added on some models as
required for FCC and CISPR 22 Class B certification.
