These power converters require a minimum 10% loading on their primary output and a
minimum 20% loading on their auxiliary outputs to maintain specified regulation. Operation
under no-load conditions will not damage these devices; however they may not meet all
listed specifications.
Application-specific internal input/output filtering can be recommended or perhaps added
internally upon request. Contact DATEL Applications Engineering for details.
Devices can be screened or modified for higher guaranteed isolation voltages.
Contact DATEL Applications Engineering for details.
On "D48A" models, the case is connected to pin 1 (+VIN).

TECHNICAL NOTES
Filtering and Noise Reduction
All A-Series TWR 8-11 Watt DC/DC Converters achieve their rated ripple and
noise specifications without the use of external input/output capacitors. In
critical applications, input/output ripple and noise may be further reduced by
installing electrolytic capacitors across the input terminals and/or low-ESR
tantalum or electrolytic capacitors across the output terminals. Output
capacitors should be connected between their respective output pin (pin 4, 5 or
7) and Common (pin 6) as shown in Figure 2. The caps should be located as
close to the power converters as possible. Typical values are listed below. In
many applications, using values greater than those listed will yield better
results.

In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these units to meet your specific requirements.
