High-Rel Fuses & Beads
High-reliability fuses and ferrite chip beads from AEM
High-Reliability Fuses and Ferrite Chip Beads
AEM's industry-leading high-reliability fuses and high-reliability ferrite chip beads are designed and screened specifically for mission-critical applications where failure is not an option.

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.
Key features of high-rel fuses:
- Zero failures in orbit for over 38 years
- Thick film fusible element construction with glass arc suppressing system
- Solid body construction with hermetically sealed gold fusing elements that ensures arc, plasma, and vapor are contained during overload current conditions
- QPL approved to MIL-PRF-23419/12, MIL-PRF-23419/13, and MIL-PRF-23419/14
Key features of high-rel beads:
- Unparalleled suppression of EMI and RFI without signal leakage
- The first and only DLA-approved ferrite chip bead designed for high-reliability use, featuring a monolithic structure with a closed magnetic path
- Designed for operation in harsh environments and extreme temperatures
- Standard EIA/EIAJ chip sizes (0603, 0805, 1206)
