DESCRIPTION

The 78250 series of converter transformers

are specifically designed for use with Maxim

chipsets to provide isolated RS232 interfaces.

Carefully controlled turns ratios ensur e

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.

Volt-time Product, E

ABSOLUTE MAXIMUM RATINGS

Operating free air temperature range

Storage temperature range

Lead Temperature 1.5mm from case for 10 seconds
