New DC EMI Filter from SynQor Helps Designers Achieve Military Standards Compliance with Confidence

SALEM, NH / ACCESS Newswire / June 2, 2026 / SynQor, Inc., announces the new MCOTS-F-28-T-HE transient half-brick filter, the latest addition to its MCOTS product family. Supporting a continuous input range from -40 to 40Vdc and transients up to 210Vdc, this half-brick module is equipped for compatibility across a broad range of military platforms and applications. Designed for the demanding requirements of defense and aerospace applications, this half-brick filter offers advanced surge, spike, and reverse-polarity protection features, enabling standard- and low-input 28Vdc MCOTS converters to meet strict military standards, including MIL-STD-461, MIL-STD-1275 B/D, MIL-STD-704, MIL-STD-810G, DO-160E, and DEF-STAN 61-5. Once started, the module will continue to deliver power down to an input voltage of 5.8 Vdc. It can deliver up to 600W or 40A continuously. To minimize stress on the power source during startup, it limits inrush current to approximately 4A, while in stand-by mode, it draws only 12 mA. When subjected to spikes and surges, its input buck stage keeps the output below 50Vdc for further system protection. The filter also includes a pass-through ON/OFF feature, enabling seamless control of downstream converters without degrading system EMI performance.

Boasting the same industry-leading rugged survivability as the rest of the MCOTS line, the MCOTS-F-28-T-HE is encased, allowing for operation in the harshest ground, sea, and air military environments. These ultra-high power density filter modules can be paired with SynQor's DC-DC converters to build military standard compliant systems. This filter streamlines and shortens the design process for systems that must meet some of the harshest military standards worldwide.
