QPL Military Quartz Crystals

QPL (or Qualified Parts List) crystals are certified and approved by the US Government's Defense Logistics Agency.  In many military and defense applications, the success of the mission (and the lives of our warfighter) depend on the reliable performance and quality of the parts within the electronic systems being use.

To be listed as an approved part in the QPL database requires process and quality audits and even part testing through DoD certified test laboratories.

All products listed herein have been qualified under the requirements for the product as specified in MIL-PRF-3098 (Quartz Crystals).

When mission success is the only option, QPL certified parts give you an added sense of assurance.
