SK406

Features

AEM, Inc. is the sole U.S. manufacturer of solid body current limiting fuses produced utilizing thick film technology with subsequent screening and qualification for spacecraft/ satellite applications. AEM, Inc.’s P600L Series Fuses have been selected by most major space programs and have been in orbit for the past 35 years with zero failures.

Applications

Used in military and commercial satellites and spacecraft including manned space vehicles

  • Protection of power supplies, batteries and solar arrays
  • Isolation of redundant and branch circuits
  • Short circuit protection from fired squib and jettison circuitry

Features

  • Consistent clearing times achieved at overload currents regardless of vacuum conditions
  • Solid body construction without outgassing and not subjected to the de-rating factors of MIL-STD-975
  • Solid body construction capable of withstanding greater vibration and shock exposure without damage
  • Positive temperature coefficient of fuse element causing resistance to increase (prior to opening) thereby preventing absolute short to the power source
  • Internal construction ensuring that arc, plasma, and vapor are contained within the fuse package during overload current conditions
  • Groups A/B data supplied with each shipment and Group C inspection optional 
  • High-reliability fuse series with over 29 million hours of life testing without a failure
  • Available as QPL Certified per MIL-PRF-23419/12
