description
The 78250 series of converter transformers are
specifically designed for use with Maxim chipsets
to provide isolated RS232 interfaces. Carefully
controlled turns ratios ensure consistent
performance whilst a toroidal construction
minimises EMI.
The surface mount devices are fully compatible
with CECC00802 to 280°C which allows them to
be placed and reflowed with IC’s thus reducing
time and cost in production.
