IAS SERIES - 12 WATT
DESCRIPTION
IAS
DC/DC converters provide up to 12 watts of output power in
an industry-standard package and footprint. With a maximum case
temperature of 100°C, the IAS is well suited for the most
demanding applications. The IAS features 1500 VDC isolation,
short circuit, and overtemperature protection, as well as six-sided
shielding. The IAS is available with optional enable and voltage
trim pins. Please see the IAD series for dual output applications.

Notes
† MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load,
unless otherwise stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully
compatible with commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model.
Please consult factory for specific model information.
Units are water-washable and fully compatible with
commercial spray or immersion post wave-solder washing
equipment.
