7 Fold Signal Trafos May-03

Seven Fold SMD Signal Transformer Modules
Features
• Low profile (5.8mm) and light weight (4.0 g) these 7 fold modules
facilitate pick and place compatability and speed of placement
• 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
