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 00-300 micro-inches matte
tin over 5-40 micro-inches of nickel.

These devices are intended for wave soldering or manual soldering.
They are not intended to be subject to surface mount processes under any circumstances.
The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of no more than 0 seconds.
Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures within the converter will not exceed 75°C. Care should
be taken to control manual soldering limits identical to that of wave soldering.

To maintain low cost, the PWR40xxC Series provides limited short-
circuit protection. To protect against continuous short circuits, a fuse is
required. It is recommended that the fuse be placed in series with the
The PWR40xxC series was designed to meet power requirements up
to 4W. Due to the nature of unregulated power supplies, a higher-than-
rated output voltage will result when less-than-rated power is used
(see Typical Performance Curves). This series has been designed to
run from no load to 4W without derating up to +70°C.
UnBAlAnCED loADS
Unbalanced loads may be used on dual output models with each side
sourcing up to 200mA as long as the total power out is not more than
4W. With an unbalanced load, the output voltages will track within
5% of each other.
oUTpUT noiSE
The output noise can be reduced to less than 50mVp-p by adding a
low ESR 0µf tantalum capacitor across each output.
