P600L

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
