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 is also a MVA-FIAM derivative version and customized version. It is widely used in aerospace, shipborne/car-mounted military electronics, and harsh industrial control scenarios. Some models can be integrated into the VIPAC series of military power supply systems with input voltage of 10-36V DC; output current of 18A; pins are long and ROHS gold-plated; operating temperature is -40 to 100℃ for 24/28V input military equipment. It has high requirements for pin materials in precise military industrial scenarios.
