Type 3203 Series
Consuming just 10.5 sq.mm of
board, the 3203 has been
developed specifically for a new
generation of hand held equipment,
where mixed technology and double
sided component placement are
unavoidable. These 3mm devices are
just 2mm high and sealed for IR,
vapour phase and full immersion wave
soldering together with solvent board
washing process. Also available
within this range is the 3213, the
auto adjust sister to the 3203.
