DLA AND ISO CERTIFICATIONS
Apex Microtechnology products deliver high quality and reliability by using the same DLA MIL-PRF-38534 certification, ISO
9001:2015 registration and qualified manufacturing systems and processes across all product grades. Apex operates a DLA certifiedand qualified QML-38534 manufacturing facility with our certification maintained since November 8, 1989, and a QML listing as ofMay 31, 1990. All products are screened to MIL-PRF-38534 and Class H.
The only point at which variables occur is during electrical testing. The M/883 equivalent (“M” grade) products are tested over awider temperature range, in addition to certain environmental screenings and internal visual inspection criteria. Commercialand industrial grade products are 100% static and dynamic tested at +25°C. Military level products are 100% tested over theirrespective full temperature ranges. For complete product and quality information, including complete technical datasheets andsupporting design documentation, or to request product samples, visit www.apexanalog.com.

POWER DESIGN SOFTWARE TOOL
Need help with selecting the best product that suits your application needs? How about
resolving key design challenges and calculations associated with your power analog circuit?
