Traction inverters represent a major application for automotive film capacitors, particularly as electric vehicle manufacturers adopt 800 V and higher-voltage powertrains. These systems require capacitors capable of handling demanding voltage conditions, ripple currents, and elevated operating temperatures while maintaining reliable inverter performance.
In February 2026, TDK Corporation introduced its B3271xP film capacitor series, offering voltage ratings of 600–1,200 V, capacitance values of 0.47–110 µF, and operating temperatures up to 125°C. Designed for traction inverters, onboard chargers, and DC-DC converters, the series reflects growing automotive demand for compact, thermally resilient power-conversion components.
Automotive Film Capacitors Beyond the Main DC-Link
Automotive film capacitors used outside the main traction DC-link generated approximately USD 198 million in 2025 and are projected to reach USD 350 million by 2032, growing at a CAGR of 8.5%. Onboard chargers, DC-DC converters, and electrical filtering systems account for much of this demand, particularly in vehicles equipped with higher-voltage charging and power-conversion systems.
Metallized polypropylene film capacitors are commonly used in these systems because of their low electrical losses and self-healing properties. The adoption of faster charging and compact power electronics is also increasing the need for capacitors that can handle higher currents and temperatures. For onboard chargers and DC-DC converters, capacitor size, reliability, and operating life are important considerations, particularly as automakers seek to reduce equipment weight and accommodate more electrical components within limited vehicle space.
How Much Revenue Do Ceramic and Aluminum Electrolytic Capacitors Generate in EVs?
Ceramic Capacitors Lead Passenger EV Capacitor Revenue
Automotive ceramic capacitor revenue was estimated at approximately USD 943 million in 2025 and is projected to reach USD 1.90 billion by 2032, growing at a CAGR of 10.5%. Ceramic capacitors represent the largest revenue category in the passenger plug-in EV capacitor market, with extensive use in battery management systems, powertrain controls, onboard chargers, and vehicle communication electronics.
Multilayer ceramic capacitors (MLCCs) account for much of this demand, particularly in electronic circuits requiring compact components with high capacitance and reliable performance. The growing use of advanced control units, higher-voltage power electronics, and vehicle safety systems is increasing the importance of automotive-qualified MLCCs. Murata Manufacturing, Samsung Electro-Mechanics, TDK, and KYOCERA AVX are among the established suppliers developing high-capacitance and high-voltage ceramic capacitors for these applications.
Aluminum Electrolytic Capacitors Serve Auxiliary Power Electronics
Aluminum electrolytic capacitors generated approximately USD 153 million in 2025 and are projected to reach USD 266.5 million by 2032, expanding at a CAGR of 8.2%. Their use is concentrated in selected auxiliary power supplies, electronic control units, and filtering circuits where relatively high capacitance and competitive component costs are important.
Manufacturers such as Nichicon and Nippon Chemi-Con supply automotive-grade aluminum electrolytic capacitors for these applications. Component selection depends on operating temperature, expected service life, and available installation space, particularly in auxiliary electrical systems that operate for extended periods under changing vehicle conditions.
How Are Higher-Voltage EV Platforms and Charging Systems Influencing Capacitor Demand?
Electric vehicle manufacturers are moving beyond conventional 400 V platforms toward 800 V and higher-voltage systems, increasing the need for capacitors suited to demanding power-conversion applications. According to the International Energy Agency's Global EV Outlook 2026, the first 1,000 V electric car models entered the market in 2025. These developments are particularly relevant to traction inverters, onboard chargers, and DC-DC converters, where capacitors must withstand higher voltages, electrical ripple, and elevated operating temperatures.
Onboard chargers and DC-DC converters use film and ceramic capacitors for electrical filtering and stable power conversion. As charging equipment becomes more compact, manufacturers face tighter requirements for capacitance, insulation reliability, and temperature resistance. The EPCI technical review also highlights ceramic Y-capacitors used for electromagnetic-interference filtering in high-voltage power electronics, an important consideration in automotive charging and conversion systems.
Which Vehicle Types Account for the Largest EV Capacitor Revenue?
Battery Electric Vehicles Lead Capacitor Consumption
Battery electric vehicle capacitor revenue was estimated at approximately USD 1.35 billion in 2025 and is projected to reach USD 2.99 billion by 2032, growing at a CAGR of 12.1%. BEVs account for the majority of passenger plug-in EV capacitor demand because of their extensive use of traction inverters, battery management electronics, onboard chargers, and DC-DC converters.
Growing BEV production and the adoption of higher-voltage powertrains are increasing demand for automotive-grade ceramic capacitors and specialized DC-link film capacitors. The use of silicon carbide power semiconductors in traction inverters has also placed greater emphasis on capacitor performance under demanding switching, voltage, and temperature conditions.
Plug-In Hybrid Vehicles Maintain Demand for Power Electronics Components
Plug-in hybrid electric vehicle capacitor revenue was estimated at approximately USD 512 million in 2025 and is projected to reach USD 684 million by 2032, expanding at a CAGR of 4.2%. PHEVs use capacitors across electric propulsion systems, onboard charging equipment, battery controls, and auxiliary electronics alongside conventional engine management systems.
Capacitor requirements vary considerably between plug-in hybrid models because of differences in battery capacity, electric motor output, and charging architecture. Manufacturers supplying ceramic and film capacitors benefit from component designs shared across related BEV and PHEV powertrain platforms, although the slower projected growth of PHEVs indicates a smaller incremental revenue opportunity than fully electric vehicles.

Emerging Technologies: Supercapacitors and Advanced Automotive Dielectrics
Supercapacitors are attracting interest in electric mobility applications requiring rapid energy delivery, frequent charging cycles, and short-duration power support. They are being explored for regenerative braking, auxiliary energy storage, and hybrid battery-supercapacitor systems, where they can help manage peak electrical loads. Their lower energy density compared with lithium-ion batteries makes them more suitable for supporting battery performance than replacing conventional EV traction batteries.
Advanced dielectric materials are also gaining attention as automakers seek smaller capacitors capable of operating at higher voltages and temperatures. Peak Nano's NanoPlex dielectric technology focuses on improving energy density and thermal performance, with potential applications in automotive power electronics. For capacitor manufacturers, the commercial value of these developments will depend on whether improved performance can be achieved at costs acceptable to automakers while meeting automotive reliability and qualification requirements.
Analyst Commentary
MarketsandStats expects DC-link film capacitors to offer stronger revenue opportunities as automakers expand 800 V and higher-voltage EV platforms. However, rising competition in conventional ceramic capacitors could put pressure on supplier margins, particularly in China. We believe manufacturers that secure long-term contracts for high-voltage inverters and charging systems will be better positioned than those relying primarily on higher component sales volumes. The key opportunity through 2032 lies in supplying higher-value capacitors for widely produced EV models while maintaining competitive manufacturing costs.
