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.
