TRJ Series • Pulse Transformers for RF Applications
These miniature transformers are suitable for pulse
applications requiring a very fast rise time and for 50 ohm
widebandRF
Features
• SMD styles are pick and place compatable and
provide consistent and reliable coplanarity
• EMI noise suppression in the common mode
• low leakage inductance
• 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
