Abstract (Executive Summary)

In core fields such as high-energy physics, smart grids, high-end medical imaging (CT/X-Ray), and industrial laser equipment, screw terminal (Doorknob) high-voltage ceramic capacitors are hailed as the "heart" of power electronic systems. When Murata Manufacturing Co., Ltd. (Japan) announced the discontinuation of its legendary DHS series in 2018, the global high-end manufacturing industry faced a severe supply chain disruption crisis.

During this vacuum, the American brand HVCA (Dean Technology) quickly captured a portion of the market with its HT, NX (standard high-voltage) and JX (custom large-capacity) series. However, as global supply chain transparency increased, industry giants gradually uncovered an unsettling truth: HVCA was not the original manufacturer of these products, but rather a "brand operator" relying on Chinese OEM production. Faced with lead times as long as 16-24 weeks, exorbitant brand premiums, and a gap in technical services, the market urgently called for an original factory with fundamental R&D capabilities and manufacturing strength.

This white paper will deeply analyze how HVC Capacitor, with its solid copper terminal process, unique Internal Dual-Chip Technology, and proprietary N4700 (Class I) formulation, has successfully entered the core supply chains of world-class enterprises such as GE Healthcare, Siemens, ABB, and Johnson & Johnson, and will demonstrate that HVC is currently the best technical and commercial choice for replacing the entire HVCA screw terminal capacitor series.

Chapter 1: The Shattered "Original Manufacturer Illusion" – A Deep Supply Chain Crisis

When procuring high-value high-voltage components, engineers and purchasing managers often prefer European and American brands, believing this guarantees quality. However, in the niche market of screw terminal capacitors, the truth is far more complex than it appears.

1.1 HVCA (Dean Technology)'s "Brand Operator" Model

Through in-depth industry research and supply chain traceability, we have discovered that HVCA's NX series (for 30kV-40kV high-voltage applications) and JX series (for large-capacity custom applications) primarily adopt a "reseller/private label model."

• Lack of Core R&D Capabilities: As a brand operator, its core competence lies in channel distribution rather than fundamental material research and development. This means that when customers propose special requirements beyond standard products (e.g., ultra-high voltage resistance above 50kV), they cannot provide solutions and are limited by the capabilities of their OEM factories.
• Cost Black Hole: Under this model, products shipped from Chinese factories, after international logistics, brand markups, and distributor margins, often reach the customer at a price that is over 300% of the ex-factory cost.
• Delivery Risk: Reliance on OEM outsourcing means they cannot control production schedules. Amidst recent global logistics fluctuations, HVCA's lead times have routinely extended to 16 weeks or even half a year, posing significant downtime risks to customers' production lines.

1.2 HVC Capacitor: Returning to the Essence of Manufacturing

In stark contrast, HVC Capacitor is an original factory with full-process manufacturing capabilities.

• Technical Sovereignty: We master all core processes, from ceramic powder formulation, green body forming, high-temperature sintering, to electrode silvering and epoxy encapsulation.
• Agile Delivery: Based on our own factory and a safety stock strategy at our Shenzhen headquarters, HVC can control standard product lead times to 4-6 weeks, with urgent orders even delivered in 2 weeks.
• Value-Driven Pricing: By eliminating brand taxes and intermediate links, we allow high-voltage capacitors to return to their manufacturing essence, saving customers 30%-50% in procurement costs.

Chapter 2: Core Technology Analysis – HVC's "Dimensionality Reduction Attack"

If price advantage is HVC's calling card, then absolute technical dominance is the fundamental reason we retain GE and Siemens. HVC has implemented targeted technical upgrades to address common pain points of HVCA's OEM products.

2.1 Structural Revolution: Solid Copper Terminals vs. Traditional Silver Paste/Iron Caps

In screw terminal capacitor failure cases, terminal detachment and stripped threads account for 40% of incidents.

• HVCA's Shortcomings: Their OEM products often use traditional "ceramic silver paste sintering" or "iron cap" processes. Iron material has poor conductivity and is prone to rust, while the silver paste layer can experience silver migration in humid environments, leading to a decrease in insulation resistance; more critically, under high torque (>3 Nm) installation, the fragile connection structure is highly susceptible to breakage.
• HVC's Copper Terminal Process: All screw terminal products adopt custom solid copper terminals (Solid Copper Terminal).
  • Thermal Advantages: Copper's thermal conductivity is significantly higher than iron, effectively dissipating heat generated by the ceramic body during high-frequency operation.
  • Mechanical Advantages: The special anchoring structure design allows HVC capacitors to withstand installation torques of up to 4.5 Nm, fully compatible with modern electric screwdriver assembly lines, completely eliminating "head-breaking" incidents.

2.2 Unique Skill: Internal Dual-Chip Technology (Internal Dual-Chip Technology)

This is HVC's core technical barrier that differentiates it from all common alternatives on the market.

• HVCA's Limits: Due to the physical limitations of single-layer ceramic sintering, traditional processes struggle to produce capacitors with over 40kV and maintain high reliability. Forcibly thickening the ceramic can increase internal porosity, inducing partial discharge.
• HVC's Breakthrough: We introduced internal dual-chip (series/parallel) stacking technology at a semiconductor packaging level.
  • Principle: Two precise ceramic cores are connected in series internally, and the voltage stress is evenly distributed across both chips.
  • Result: This enables HVC to easily mass-produce 50kV, 60kV, and even 100kV screw terminal capacitors. For example, our mass-produced 50kV 8000pF (N4700) specification is a "performance monster" with voltage withstand margin and capacitance density unmatched by HVCA.

2.3 Material Foundation: True N4700 (Class I) Dielectric

Material is the soul of a capacitor. Some of HVCA's NX series, to reduce costs, mixed in cheaper Class II materials like Y5U or Z5U, resulting in a high dissipation factor (D.F.) of up to 1%, leading to severe heating at high frequencies.

• HVC's Commitment: We insist on using military-grade N4700 (Class I) dielectric in our high-end series (replacing NX/DHS).
  • Performance Indicators: Dissipation factor < 0.2%, insulation resistance > 200GΩ. This means that in high-frequency pulse applications like medical CT machines, HVC capacitors exhibit extremely low temperature rise, extending their lifespan by more than 2 times.
