AEM’s High-Reliability Solid-Body Fuses Added to European Preferred Parts List (EPPL)

AEMAEM, Inc. has announced that its FM12 line of solid-body fuses has been selected by the European Space Components Coordination (ESCC) body for inclusion in the European Preferred Parts List (EPPL). The FM12 Series fuses, also included on the Defense Logistics Agency Qualified Products List (QPL), are intended for use in a wide variety of aerospace applications that require the highest level of reliability.

AEM’s high-reliability FM12 solid-body fuses feature a precision thick-film fusible element with a glass arc suppressing system that ensures that arc, plasma, and vapor are contained within the fuse package during overload-current conditions. The positive temperature coefficient of the fuse element causes an increase in resistance (prior to opening), thereby preventing an absolute short circuit to the power source. The devices are rated for operation between -55ºC and +125ºC. No current or voltage derating is required during vacuum operation.

“We are delighted to learn that our FM12 fuses are now included in the EPPL,” says AEM’s marketing director, Scott Sentz. “With over 30 years in orbit with zero reported failures, AEM fuses have long been recognized and utilized by every major producer of satellites and spacecraft hardware. And now we are also recognized by the European Space Agency as a qualified parts provider.” Sentz adds, “AEM has a proven commitment for supplying the highest-quality components while meeting expectations for service and delivery.” Typical lead times for most FM12 series fuses range from two to 16 weeks.

AEM’s MIL-STD-790 and AS9100 certified facility in San Diego, California will continue to provide unique component solutions to meet mission critical program needs. 


AEM will be exhibiting at Space Tech Expo USA in stand 4024.
