DESCRIPTION
The PWR40XX Series offers a low-cost alternative for some
of the most popular DC/DC converters industry wide. Each
model has a high-isolation version and an outstanding
demonstrated MTTF of 5,000,000 hours at 25°C. The superior
reliability and low cost make it an excellent choice for industry
standard usages.
The series includes thirteen standard models (other input
and output voltages are available upon request), all set in a
flexible encapsulation material which has excellent thermal
dissipation and low mechanical stress on internal components.
The use of surface-mount devices and manufacturing
processes, combined with the encapsulation process, provides
the user a product that is environmentally rugged.
The PWR40XX has full isolation between input and output to
give the designer maximum flexibility in grounding options
and polarity configurations. The outputs are protected against
momentary short circuits.

MATERIAL: Units are encapsulated in a low thermal resistance
molding compound which has excellent chemical resistance, wide
operating temperature range, and good electrical properties under
high humidity environments. The encapsulant and outer shell of
the unit have UL94V-0 ratings. Lead material is brass with a solder
plated surface to allow ease of solderability.
