APPLICATION NOTES
APPLICATION CIRCUIT
All of these part types have been designed to provide signal performance optimization, maximum noise reduction and
minimum crosstalk interference. Careful board layout and grounding techniques are also critical to control jitter and
signal reflections.
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.
