converter applications

• Designed to support the growing need for efficient

DC/DC converters in battery operated equipment

• Two separate windings provide versatility by ability

to connect windings in series or parallel

• Operating temperature range: - 40 °C to + 125 °C

• Supplied on tape and reel and is designed to be pick

and place compatible

• Custom versions and turns ratios available. Contact the factory

with your specifications
