The HUA/HUD Series is ideally suited
for many analog and digital applica-
tions in process control, microproces-
sors, telecommunications and auto-
matic test equipment
Applications
he HUA/ HUD is a cost-effective
series of DC/DC converters,
offering both single and dual
outputs. These unregulated converters
offer the latest in MOSFET technology.
Featuring efficiencies to 80%, cool
operating case temperatures and a
high level of reliability with a MTBF in
excess of 1,000,000 hours. Additional
standard features include an internal Pi
filter, 500 Vdc I/O isolation, up to 12
watts of output power and operating
temperature of –25°C to +71°C with no
derating. All this in a package measur-
ing 2.0” x 2.0” x 0.40” high.
