DESCRIPTION
The PWR40xxC 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 exible 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 PWR40xxC has full isolation between input and output to give
the designer maximum exibility in grounding options and polarity
congurations. The outputs are protected against momentary short
circuits.

MATERIAL:Units are encapsulated in a low thermal resistance molding com-
pound 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
base metal is phosphor bronze; lead nish is 100-300 micro-inches matte
tin over 5-40 micro-inches of nickel.
