Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.

Radial leaded aluminum electrolytic capacitors are a type of polarized capacitor where aluminum foil functions as the anode and paper soaked in electrolyte serves as the cathode, with both leads extending from one end of the cylindrical body. These capacitors are designed for through-hole mounting on printed circuit boards (PCBs) and are extensively used in power supply filtering, energy storage, and decoupling applications due to their high capacitance and cost-effectiveness.

The main categories of radial leaded aluminum electrolytic capacitors include those with solid aluminum electrolytes and those with non-solid aluminum electrolytes. Solid electrolyte types are known for improved stability, lower equivalent series resistance (ESR), and longer operational life, making them ideal for applications requiring durability and high frequency. These capacitors are grouped based on capacitance into low capacitance (1 µF - 100 µF), medium capacitance (100 µF - 1,000 µF), high capacitance (1,000 µF - 10,000 µF), and ultra-high capacitance (>10,000 µF). In terms of voltage rating, they are categorized as low voltage (up to 25V), medium voltage (25V - 100V), high voltage (100V - 400V), and ultra-high voltage (>400V). These capacitors are broadly utilized across industries such as consumer electronics, telecommunications, automotive manufacturing, aerospace and defense, and medical devices.
