What are the brands of solid-state capacitors?

The following is a classification and sorting of mainstream brands of solid-state capacitors, based on their comprehensive technical strength, market share, and application fields, divided into four major technical camps:
1、 Japanese and Korean series: technology leads, dominates the high-end market
Murata Productions (muRata)
Global MLCC leader, leading in ultra micro capacitor (01005 size) technology, excellent high-frequency performance, suitable for 5G RF modules and wearable devices.
Nichicon
Polymer polymerization technology is outstanding, with leakage current as low as 10 μ A or less, specializing in precision circuits (such as ADC modules for medical equipment).
Nippon Chemi Con (Black Diamond)
Our self-developed electrode foil technology achieves the lowest ESR in the industry, and our high-voltage high-capacity products (400V/15000 μ F) monopolize the industrial frequency converter market.
Panasonic
Tantalum polymer capacitors have excellent high-frequency characteristics (supporting 10MHz filtering), and the automotive grade FK series has passed AEC-Q200 certification.
Samsung Electric (SEMCO)
Large capacity solid-state capacitors (≥ 1000 μ F) have high cost-effectiveness and a market share of over 30% in server power supply.
2、 European and American series: automotive standards and military grade benchmarks
KEMET (now a national giant)
Polymer tantalum capacitors have high temperature resistance (175 ℃) and strong vibration resistance, and are used in aerospace power systems.
Vishay
The low ESR series (such as 594D) has a ripple current of 5A and is suitable for new energy vehicle OBC (on-board charger).
Cornell Dubilier
The patented organic polymer technology (such as ESRE series) has a capacitance density three times higher than traditional aluminum electrolysis.
3、 Chinese Mainland: the main domestic alternative
Fenghua High Tech (FH)
Vehicle grade products have passed AEC-Q200 certification, and high-voltage capacitors (500V) for photovoltaic inverters are shipped in bulk.
EYANG Technology
Ultra micro MLCC is compatible with solid-state technology, and 01005 size capacitors are used for 5G mobile phone motherboards.
AiSHi Group
The mixed electrolyte technology extends the lifespan (105 ℃/5000 hours) and has the highest market share of fast charging power supplies in China.
Capxon Electronics
High cost-effective consumer grade capacitors, with a global market share of over 20% for laptop power adapters.
4、 Taiwan, China: the core of the consumer electronics supply chain
National Giant (YAGEO)
After integrating Jimei, the production capacity of automotive capacitors has doubled, and the TAC series supports a wide temperature range of -55 ℃~150 ℃.
WALSIN Technology
Low ESR polymer capacitor (DF value ≤ 0.1), with a penetration rate of over 40% for gaming motherboards.
Lelon Electronics
Solid state aluminum electrolytic capacitors have a lifespan of 105 ℃/8000 hours and are compatible with LED driver power supplies.
Brand technology positioning and typical applications
Faction technology advantages represent product application scenarios
Japanese and Korean high-frequency low loss, ultra miniature 5G base station RF module, automotive ECU
European and American military grade reliability, wide temperature tolerance aerospace power supply, new energy vehicle OBC
Chinese Mainland is a cost-effective, home-made alternative photovoltaic inverter and consumer power adapter
Taiwan, China based standardized production capacity, low ESR design E-sports main board, industrial control board
Selection suggestions
High end fields (automotive/military): Priority given to Japanese and Korean brands (Nichicon, Black King Kong) or European and American brands (Jimei);
Cost sensitive scenario (consumer electronics): Chinese Mainland (Fenghua High tech, Aihua) and Taiwan (Huaxinke) are better;
High frequency applications: Panasonic tantalum polymer or Murata high-frequency MLCC are preferred.
Note: The above brands cover 90% of the global market share, and specific parameters need to refer to the manufacturer's datasheet. Domestic manufacturers are accelerating the certification of vehicle specifications, and it is expected that the share of mainland brand vehicles will exceed 30% by 2025.
