By Klaus Jing & Dr. Liwu Wang

San Diego, California, Oct 08, 2023 – We are pleased to announce that all AEM automotive grade surface mount fuses meet new regulations of AEC-Q200 Rev E. The new AEC-Q200 Rev E defines clear requirements for fuses performances before and after the stress tests which set a higher standard for safety and reliability. The AEC-Q200 Rev E provides a wide range of performance reliability and high I²t values to ensure high inrush current withstand capability, offering an array of component options and design flexibility in providing circuit protection against abnormal overloading and surging conditions.

AEM is well-known in the industry and market for providing one of the most extensive and comprehensive surface mount fuses for circuit protection. AEC-Q200 Rev E qualified AEM fuses are manufactured at the ISO14001 & IATF16949 certified facility. AEM surface mount fuses are setting a new standard for reliable performance for automotive electronics and electric vehicle applications. AEM automotive grade product portfolio includes AirMatrix^® (Wire-In-Air Surface Mount Fuse), SolidMatrix^® (Co-fired Solid Body Surface Mount Fuse), QMF High Power Fuse and Polymer PTC Resettable Fuses.
