Tantalum is one of the most critical materials affected by the new DFARS 252.225-7052 requirements, yet many companies don’t realize how extensively it’s used in their products.
Tantalum is prized for its ability to store electrical charge efficiently and resist corrosion. You’ll find it in capacitors — the most common use — with almost every electronic circuit board in modern systems containing tantalum capacitors. It also appears in high-performance electronics such as radar systems, communication equipment, and sensors, as well as in power management systems critical for battery-powered devices and voltage regulation.
In aerospace and naval systems, tantalum is commonly found in avionics, navigation equipment, and shipboard electronics. Its unique properties make it difficult to replace in many high-reliability applications.
Even “simple” commercial components like tablets, VR headsets, displays, and computers often contain tantalum capacitors. When these devices are integrated into a defense training system or any other end item, they typically lose their COTS exception and require full supply chain tracing.
The challenge many companies face is that suppliers cannot easily provide detailed origin information for the tantalum used in their components. This creates compliance gaps that must be addressed through reasonable inquiry and mitigation plans. The situation is further complicated by the fact that tantalum supply chains are often long and complex, with multiple tiers of suppliers and processors involved.
If your products contain electronic components — which most do — it’s time to assess your exposure to tantalum and other covered materials. Taking a proactive approach now can save significant time, cost, and risk later when audits and delivery requirements become more stringent.
RavenClear provides full-service compliance solutions to help you identify these risks and build defensible documentation that meets regulatory expectations while supporting your program timelines.
