High-Reliability Fuses

  • The challenge: Standard fuses can struggle in low-pressure or vacuum environments, like space or high-altitude avionics. When a fuse blows in these conditions, the result can be catastrophic; a single local fault can cause a cascade of short circuits and become a mission-ending event.
  • The AEM solution: Our high-reliability fuses provide the answer, ensuring that all arc, plasma, and vapor are fully contained within the hermetically sealed body, preventing collateral damage to the system. 
  • Applications: Satellite constellations, manned and unmanned spacecraft, and military and defense avionics.

High-Reliability Ferrite Beads

  • The challenge: Electromagnetic interference becomes a major threat as designers pack more power and high-frequency signals into smaller PCB footprints, especially in satellite payloads and military comms. Standard beads often shift in impedance or fail when exposed to extreme temperature swings or radiation.
  • The AEM solution: We provide the only DLA-approved ferrite chip bead designed specifically for high-reliability use. Our beads provide unparalleled EMI and RFI suppression, ensuring signal integrity from the bottom of the ocean to deep space.
  • Applications: Military and aerospace communications, space payloads, and subsurface activities including downhole and undersea.
