Applications

Talema 10/100BaseT Dual 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.

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.

Features

• Low profile and light weight 10/100 BaseT modules facilitate

pick and place compatability and speed of placement

• Meets requirements of IEEE 802.3u and ANSIX3.263

• Consistent and reliable coplanarity

• Excellent quality at extremely competitive price due to high

volume production

• 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
