If you’re designing with EMC in mind, note that all of DATEL’s BWR 3 Watt
DC/DC Converters have been characterized for radiated and conducted
emissions in our new EMI/EMC laboratory. Testing is conducted in an EMCO
5305 GTEM test cell utilizing EMCO automated EMC test software. Radi-
ated emissions are tested to the limits of FCC Part 15, Class B and CISPR
22 (EN 55022), Class B. Correlation to other specifications can be supplied
upon request. Radiated emissions plots to FCC and CISPR 22 for model
BWR-5/250-D12 appear below. Published EMC test reports are available for
each model number. Contact DATEL’s Applications Engineering Department
for more details.
