Flexible. Powerful. Reliable. These are words that best describe P-DUKE’s series of electronic components for military/defense and industrial applications. P-DUKE, a leading manufacturer of high-performance power conversion products, has developed the MCF series of MIL-COTS DC/DC front-end filters. These products are designed to meet the strict requirements of MIL-STD 1275E (28V DC electrical systems in military vehicles) and MIL-STD 461 (electromagnetic interference control for subsystems and equipment). 

The front-end filters also accept 9-36Vdc input voltage, making them suitable for military vehicles and aircraft with 28V or 24V bus systems. They are also applicable to heavy industrial and rolling rock applications. 

Safe in Any Environment

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. 

What Makes the MCF Series Unique

What’s unique about P-DUKE’s MCF modules? The series is designed for military and rolling stock applications, so when used with P-DUKE’s COTS DC/DC converters, offers significant cost savings compared to traditional military DC/DC converters in the power range of up to 250W. 

Other cool factors – the MCF-208 module features complete protection and a wide range of wattage covers from 15W to 250W. The module also is integrated with both the EMI filter and surge protection, whereas most similar parts are only integrated with either the EMI filter or surge protection. 

The MCF filter module also reduces design time, saves system space, and provides comprehensive system protection. The MCF filters meet environmental MIL-STD 810F specifications for shock and vibration and have an operating temperature range of -40°C to 105°C.
