Key Explanations

Differences between the Four Core Series (Quick Differentiation)

1. • M-FIAM3 series: Designed for 300V high voltage input, with an output current of 3A, it is compatible with Maxi, Mini, and Micro DC-DC converters and VI Chip modules with 300V input. Transient compliance is mainly based on MIL-STD-704 [1][5][6]

2. • M-FIAM5 series: Adapted to 24/28V input (14-36V), output current 20A, only supports MIL-STD-704 single transient protection standard, mainly for basic military filtering protection [2][6]

3. • M-FIAM7 series: Derived from MVA-FIAM, focusing on power line filtering, mostly chassis mounting or through-hole soldering, some models have limited supply, suitable for military power line protection scenarios [3]

4. • M-FIAM9 series: Adapted to 24/28V input (10-36V), output current 18A, supports MIL-STD-704 and MIL-STD-1275 dual transient protection standards, suitable for complex vehicle and shipboard scenarios [4][6]
