The VICOR M-FIAM series is a DC front-end input filtering and attenuation module specifically designed for military and harsh industrial environments. Its core function is to provide EMI filtering and transient surge protection. It can be used in conjunction with VICOR's Maxi, Mini, Micro series of DC-DC converters with 24V, 28V or 300V input, as well as the MIL-COTS VI Chip module with 28V input. It meets the MIL-STD-461E requirements for conducted interference/conducted sensitivity, and also complies with the MIL-STD-704 or MIL-STD-1275 military transient protection standards. This series is divided into four core series: 3/5/7/9. There are also MVA-FIAM derivative and customized versions. It is widely used in aerospace, shipborne/carborne military electronics, and harsh industrial control scenarios. Some models can be integrated into the VIPAC series of military power supply systems for input voltage, filtering accuracy, protection level, and specific customization for military scenarios ranging from -55 to 125°C. It is also suitable for dedicated shipborne/carborne military equipment.
