Quick answer: post-launch guides describe Capacitors as a rare resource used for permanent facility/company upgrades in the Den. EA's public help pages confirm the broader base-upgrade and mission-reward systems, but EA has not published a complete official Capacitor drop table. Exact mission names and quantities should therefore be verified in your live campaign.
What Capacitors are used for
Independent post-launch documentation reports Capacitors alongside Credits as requirements for selected permanent facility upgrades. That makes them a strategic progression resource rather than normal combat ammunition or a consumable utility.
The safest way to use this information is to check the cost shown by the upgrade terminal in your current game version. If an upgrade displays a Capacitor requirement, that UI is more authoritative than a static guide written before future patches.
Where Capacitors come from
Community/post-launch guides report three broad sources: selected Tactical Mission rewards, influence/progression payouts and certain Operation outcomes. Because those exact rewards depend on campaign state and can be patched, this page intentionally does not publish an unverified "every Capacitor location" table as official fact.
When choosing between missions, inspect the reward panel before deployment. If Capacitors are currently your progression bottleneck, prioritize an opportunity only when the live UI explicitly shows the resource or a trusted current guide has verified the same campaign condition.
Why this page uses Source Tier B
The keyword has real player intent, but official EA help currently provides far better detail for Specializations, weapons, PC settings and troubleshooting than for Capacitor locations. Rather than pad the article with generic resource-management advice, this page labels the evidence gap.
If EA publishes an official facilities/resource guide, this page should be upgraded to Source Tier A and expanded with exact costs and reward routes. Until then, specific numbers remain secondary-source information.
Spending strategy
Permanent upgrades compete for a scarce resource, so spend according to your campaign bottleneck. If roster capacity, economy or influence access is blocking progress, prioritize the facility that removes that constraint. Avoid spending solely because an upgrade is available; compare its benefit with the next likely Capacitor opportunity shown by the campaign.
