TM Series • 10 Base-T Single Port SMD Transformer Modules
Features
• Low profile and light weight 10 Base-T modules facilitate pick
and place compatability and speed of placement
• Meets requirements of IEEE 802.3
• 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
Electrical Specifications @ 25°C
Minimum isolation voltage: 1500 Vrms
Operating Temperature Range: -40°C to +85°C
Storage Temperature: -40°C to +125°C
Test Frequency: Inductance, Interwinding Capacitance and
Leakage Inductance measured @ 100kHz/20mVrms
Standard Packing: Tape and Reel
Quality and consistency are 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 10Base-T 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.
