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.
