IEC PAS 62686-2:2016(E) defines the minimum requirements for general purpose 'off the shelf' COTS passive components for ADHP (Aerospace, Defence and High Performance) applications. This specification shall be used wherever possible for components that typically can be applied to operate in high reliability applications within the manufacturers publicly available datasheet limits. This specification has been derived from STACK Specification S/0003 issue 02. Adoption of the STACK Specification S/0003 issue 02 will enable all existing STACK Certified manufacturers to be audited by IECQ under the STACK-IECQ joint venture. This publication is to be read in conjunction with IEC 62239-1:2015 for avionics applications.
