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 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 PWR40xxC 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 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 finish is 100-300 micro-inches matte

tin over 5-40 micro-inches of nickel.
