Shirley, N.Y. -- Modular Devices, Inc. (MDI) offers a compact DC/DC converter with a built-in EMI filter that meets MIL-STD-461 D, E and F, eliminating the need for external EMI filtering. The Series 3090 converters enable more efficient compliance with the latest electromagnetic interference compatibility (EMC) requirements for aerospace, defense, and civil aviation airborne electronics, said the company.
According to MDI, the Model 3090 has a highly damped EMI filter design, providing superior performance in rejection of conducted susceptibility (MIL-STD-461 revisions D, E, and F method CS101 and CS102) inputs. The 5-watt DC/DC converters operate from nominal 28 VDC power sources. Models are available with single or dual outputs, and are packaged in a hermetic case that measure 1.08 inches square x 0.380 inches. The 3090 design is sufficiently robust to operate through MIL-STD-704A 80V/100mS power line transients, said MDI.
"The small size and high compatibility of the 3090 series make it a valuable solution to engineering design challenges as the demand for quieter DC/DC converters becomes more prevalent," said Steven E. Summer, MDI president, in a statement. "Moreover, the 3090 design allows companies to stock a single part for different applications."
A 30-watt series of DC/DC converters with built-in EMI filters will be available later this year.
