APPLICATION CIRCUIT
APPLICATION NOTES
• Transmit turns ratio is 1CT:2CT. Receive turns ratio is 1CT:1CT.
• Bel's low profile, surface mount packaging is ideal for high speed pick and place machinery. Parts can be shipped on
tape and reel for high speed placement. Construction processes have been implemented for thermal compatibility with
high temperature IR reflow assembly processing. Post dipping of leads assist with PC board solderability. Each part
is optically inspected to meet rigid coplanarity requirements.
