Analysis of the advantages of three ring CCTC surface mount capacitors
1、 Technological innovation and breakthroughs in localization
As a leading enterprise in the field of electronic components in China, Sanhuan Group has achieved breakthroughs in the entire industry chain from materials to products in the field of surface mount capacitors (MLCC) through independent innovation and technological accumulation. Its core advantages are reflected in the following aspects:
Breakthrough of technical barriers: For a long time, the MLCC market has been dominated by Japanese and Korean companies, but Sanhuan Group has successfully broken through the technological blockade through material research and development and process innovation. For example, its dielectric layer thickness technology has been increased from 5 microns to 1 micron, significantly improving capacitor capacity and performance, and achieving localization of key specifications.
Domestic substitution capability: Three ring MLCC products cover over 90% of specification requirements, especially in wireless charging, automotive electronics and other fields. MLCC capacitors developed based on M3L material have performance comparable to international mainstream NPO capacitors, and their prices are only 1/4 of imported products, achieving seamless substitution.
Capacity guarantee: In 2024, the monthly production capacity is close to 55 billion units, and by 2025, the investment will be further expanded to a scale of billions to ensure supply chain stability and support the domestic substitution of high-capacity capacitors.
2、 Integration of high-capacity and miniaturization technologies
Three ring MLCC follows the trend of "1 small, 4 high" (miniaturization, high capacity, high frequency, high reliability, high voltage) and launches a series of high capacity products:
Technological breakthrough: By optimizing the ceramic medium formula and multi-layer stacking process, the combination of small size (such as 0201 packaging) and large capacity can be achieved. For example, the 0402 size product has a capacity of up to 100 μ F, meeting the high-density circuit requirements of 5G smartphones, new energy vehicles, and other applications.
Application Scenario:
Consumer electronics: Small size (0201/0402) and low ESL high-frequency models (such as X7R 0402 100nF) are required for power filtering (CPU powered) and RF front-end (matching network, antenna tuning) of mobile phones/tablets.
Automotive Electronics: The MLCC usage of a single intelligent vehicle exceeds 10000 pieces, and the high capacity products of Sanhuan have performed outstandingly in the fields of power systems, ADAS, etc., supporting the upgrading of automotive electrification and intelligence.
High frequency performance: Low ESR (equivalent series resistance) and low loss characteristics ensure stable operation of high-frequency circuits (such as communication base stations), with performance comparable to international competitors.
3、 M3L material: Innovation in wireless charging field
The M3L ceramic medium developed by Sanhuan for wireless charging optimization combines performance and cost advantages:
High frequency and low loss: suitable for LC oscillation circuits, with low heat generation and charging efficiency comparable to C0G capacitors, supporting 5W to 10W wireless charging solutions.
Temperature stability: The capacity change rate is as low as -0.1%, and the bending strength and DC bias performance are comparable to C0G, making it suitable for harsh environments.
Packaging flexibility: Provides a full range of packaging from 0603 to 1206 to meet the space requirements of ultra-thin devices. It has been widely used in mainstream wireless chargers, replacing traditional CBB capacitors and solving size and cost problems.
4、 The entire industry chain is independently controllable
Sanhuan Group builds its core competitiveness through a three in one research and development system of "materials+equipment+processes":
Material research and development: Starting from basic ceramic materials, entered the field of capacitors after 2000, accumulated more than 20 years of experience, and accumulated rich experience in the field of high capacitance technology.
Intelligent Manufacturing: The four major production bases (Nanchong, Deyang, Shenzhen, Chaozhou) are equipped with high-precision equipment to achieve rapid response from research and development to mass production.
Environmental certification: The product complies with RoHS standards and uses halogen-free packaging technology to help customers meet global environmental regulations.
5、 Widely applicable scenarios and reliability
Three ring CCTC surface mount capacitors are widely used in various fields, reflecting their high reliability and adaptability:
Consumer Electronics:
Mobile phone/tablet: power filter, RF front-end, audio coupling require small size, low ESL model.
TWS earphones: Ultra small size (01005/0201) MLCC for charging case power management.
Automotive Electronics:
ECU module: High reliability MLCC (AEC-Q200 certified) can withstand wide temperature range of -55 ℃~+150 ℃, vibration and shock, and is used for engine control, ABS and other modules.
BMS system: Low ESR/ESL high voltage MLCC (such as 100V~250V X7R) is used for battery voltage sampling and capacitor voltage division.
Industrial control:
PLC equipment: Large capacity MLCC (such as 470 μ F~1000 μ F) filtering, capable of withstanding industrial environmental temperatures (-40 ℃~+85 ℃).
Inverter: High voltage MLCC (X7R or high-voltage ceramic) absorbs surge current and reduces IGBT module stress.
Communication equipment:
5G base station: Low loss C0G MLCC (0402~0603) matched with RF circuit; High voltage MLCC (X7R) stable power module power supply.
Satellite communication: Anti radiation MLCC is used for signal processing in satellite payload circuits.
6、 Cost advantage and supply chain guarantee
Process optimization: Adopting the base metal electrode (BME) process, replacing traditional Ag/Pd electrodes with Cu/Ni, reducing sintering shrinkage, allowing for thinner dielectric layers (d ≤ 0.8 μ m), increasing the number of layers (≥ 2000 layers), and achieving small size and large capacity.
Large scale production: With a monthly production capacity of nearly 55 billion units in 2024, it aims to reach a scale of billions by 2025, ensuring supply chain stability and reducing procurement costs.
Price competitiveness: M3L material capacitors are priced at only 1/4 of imported NPO products, helping customers create cost-effective products.
7、 Future Development Trends
Driven by the demand for 5G, new energy vehicles, and AIoT, the three ring MLCC is evolving in the following directions:
Breakthrough of contradiction between miniaturization and large capacity: increase the density and reduce ESR and ESL through nano ceramic medium (prepared by sol-gel method).
High frequency: Optimize ceramic formula (add MgO, ZrO ₂), reduce dielectric loss tangent (tan δ ≤ 10 ⁻⁴), meet 5G RF (28GHz/39GHz) and Wi Fi 6E (7.8GHz) requirements.
Low ESL design: Adopting a "multi terminal" structure (such as 4-terminal/8-terminal MLCC), shortening the current path and reducing parasitic inductance (ESL ≤ 1nH), suitable for high-speed digital circuits (such as DDR5 memory power supply).
Conclusion
Three ring CCTC surface mount capacitors have set a benchmark for domestic substitution in the MLCC market with technological innovation, high capacitance, high frequency and low loss, independent controllability of the entire industry chain, wide application scenarios, and cost advantages. Its products not only have performance comparable to international competitors, but also provide cost-effective solutions for global customers through large-scale production and material technology breakthroughs, helping electronic devices develop towards miniaturization and higher performance.
