The designs have been created to provide 350µH OCL with 8mA DC bias applied. Consult the Bel short form catalog and applicable application circuit for the specific configuration of each individual part type. • 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.
