High-reliability solid body fuses added to European Preferred Parts List

AEM’s FM12 line of solid body fuses have 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. Their 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 -55C and +125C. 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," said 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 added, "AEM has a proven commitment for supplying the highest quality components while meeting expectations for service and delivery."
