Mil-COTS DC/DC Filters – MCF028 Series


Mil-COTS DC/DC Filters – MCF028 Series

P-DUKE has developed the MCF series, MIL-COTS DC/DC front-end filters, to meet the requirements of MIL-STD 1275E (28V DC electrical systems in military vehicles) and MIL-STD 461 (electromagnetic interference control for subsystems and equipment). These filters accept 9-36Vdc input voltage, making them suitable for military vehicles and aircraft with 28V or 24V bus systems, and they are also suitable for heavy industrial and rolling stock applications.

The MCF series features active input over-voltage protection, clamping over-voltages for up to 50ms to a safe level of 40V, and absorbing +/-250V spikes. With additional MLCCs, the internal EMI filter meets MIL-STD 461G limits. It also includes various active protection functions for advanced protection of the DC/DC converter module.

The MCF filter module is fully integrated and complies with MIL-STD 1275E, MIL-STD 461G, EN 50155, RIA 12, and NF F 01-510 standards. It reduces design time, saves system space, and provides comprehensive system protection. The MCF filters also meet environmental MIL-STD 810F specifications for shock and vibration and have an operating temperature range of -40°C to 105°C (optionally -55°C).

Designed for military and rolling stock applications, the MCF modules, when used with P-Duke COTS dc/dc converters, this solution offers significant cost savings when compared to traditional military DC/DC converters.
