APPLICATION NOTES
• All receive transformers (except for S553-1084-05) have 1CT:1CT turns ratio.
• Multiple design options offered to optimize individual PCB layouts and grounding configurations. Consult Bel
engineering for assistance in choosing the best solution.
• 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.
