P-DUKE has launched the new MCF series which are front-end filters for P-DUKE COTS (commercial-off-the-shelf) DC/DC converters to comply with the requirements of MIL-STD 1275D (Characteristic of 28 volt DC electrical systems in military vehicles) and MIL-STD 461 (Requirement for the control of electromagnetic interference characteristics of subsystems and equipment). This filter series accepts 9-36Vdc input voltage (50Vdc for 1 sec.) which is suitable for military vehicle with 28V bus systems respectively 24V bus systems They are also applicable for both heavy industrial and rolling stock applications.

The MCF series offers active input over-voltage protection which clamps over-voltages for maximum 50ms up to 100V to a safe level of 40V and absorbs +/-250V spikes with the internal protection circuits. By connecting the MCF module with a few additional MLCCs, its internal EMI filter meets MIL-STD 461G limits. Besides, it also features other active protection functions for an advanced protection of the DC/DC converter module such as remote on/off control, overload protection, output short-circuit protection, reverse polarity protection, inrush current limitation, etc.

The MCF filter module is a fully integrated front-end module. In addition to complying with MIL-STD 1275D and MIL-STD 461G, it also fulfills the EN 50155,
RIA 12 and NF F 01-510 standards for rolling stock 24V bus systems. It greatly reduces the time to design the EMI-filter and peripheral circuits, save system space and provide a comprehensive system protection.
The MCF filters meet the environmental MIL-STD 810F specification for shock and vibration. The operating temperature range of -40°C to 105°C (optionally -55°C) allows to use these MCF filters with P-Duke DC/DC converters in a wide range of demanding applications.
The MCF modules are especially designed for military and rolling stock applications. Together with P-Duke COTS DC/DC converters, a significant cost saving is offered compared to using traditionally developed military DC/DC converters in the power range of up to 250W.
