Hi-Rel Fuses
AEM is the sole QPL listed manufacturer of solid body, current limiting fuses produced using a thick film technique for the aerospace industry. Our fuses have been chosen by most major space programs and have been in orbit for the past 30-plus years with zero reported failures.
Applications
Features
Used in military and commercial satellites and manned space vehicles.
Protection of power supplies, batteries and solar arrays.
Isolation of redundant and branch circuits.
Short protection from squib and jettison circuitry.
Consistent minimum and maximum clear-times at overload currents regardless of vacuum conditions.
Solid body construction does not outgas and therefore is not subjected to the de-rating factors of Mil-Std-975.
Solid body construction can withstand greater vibration and shock exposure without damage.
Positive temperature coefficient of fuse element causes resistance to increase (prior to opening) thereby preventing absolute short to the power source.
Internal construction assures that arc, plasma, and vapor are contained within the fuse package during overload current conditions.
P600L fuses have been subjected to over 6 million hours of life testing without a failure.
QPL Certified/Mil-PRF-23419/12.
Hi-Rel Fuses
FM12A
AEM's QPL Certified/Mil-F-23419/12.
P300L
AEM's P300L fuse series was developed from the P600L offering our customers a cost saving alternative for some applications. The P300L exhibits an expanded blow time range at 250% overloads.
P600L
AEM's P600L fuse series is the commercial version of the QPL'd FM12A series.
P700L
AEM's P700L fuse is a surface mountable version of our solid body series. It is available on tape & reel for automated manufacturing processes.
P800L
AEM's P800L slow blow fuse series was designed to operate with slower clearing times, providing engineers additional flexibility in their electrical designs.
SM1206
AEM's SM1206 solid body chip fuse series was designed for surface mounting in lower voltage applications. It is available on tape & reel for automated manufacturing processes
SK406
AEM's SK406 series is a modified lead configuration of the P600L, providing the design engineer additional flexibility of surface mounting the popular P600L series.
SK2000
AEM's SK2000 is designed to handle extremely high currents at low voltage. Applications including cell shorting and battery protection.
Non Standard & Custom
We offer a wide range of higher voltage, devices not found in our standard solid body product offerings. Also available are custom lead configurations and matched sets. Please contact the factory with your fusing requirements.
