Supply Chain Resilience Upgrade: Solving the AVX Exit Crisis with HVC

Executive Summary

In 2018, the global HV doorknob capacitor market suffered a double blow: Murata and AVX both announced their exit. Vishay continues production but with 14-34 week lead times and the industry's highest pricing. This white paper examines how HVC, through its fully owned production lines, N4700 material technology, and flexible supply chain management, delivers a drop-in replacement solution for medical imaging, power equipment, and scientific testing industries — while simultaneously achieving cost optimization and lead time reduction.

1. Market Background: The Chain Reaction of Three Brand Crises

1.1 First Wave: Murata Exit (August 2018)

Murata announced the discontinuation of its HV bolt ceramic capacitors (DHS/DHK series). The market initially turned to AVX and Vishay, but soon discovered this was only the beginning of the crisis.

1.2 Second Wave: AVX Exit (October 2018)

Just two months later, AVX announced its exit from the HV doorknob capacitor market (HP/HW/HK/HD/HE/HZ series), closing its French TPC factory which had been in production since 1998. AVX was the only brand offering 100KV-rated products, making its exit a critical supply risk for high-end applications such as aerospace and military.

1.3 Vishay: Still in Production but with Limitations

Vishay's 715C series remains in production, but with lead times stretched to 14-34 weeks, premium pricing, and the use of Y5U Class 2 ceramic for high-capacitance models (unsuitable for HV pulse applications), it is far from an ideal solution for customers demanding both performance and timely delivery.

2. Technical Deep-Dive: Why HVC Can Fill the Gap Left by All Three Brands

2.1 Core Material: Full N4700 Class 1 Ceramic

HVC collaborates with a state-level military research institute, holding a patented N4700 ceramic dielectric formulation. Compared to AVX's strontium-based Class 2 ceramics and Vishay's Y5U downgrade option, N4700 delivers superior D.F., temperature stability, and insulation resistance across the board.

5. Solution Portfolio: From "Replacement" to "Upgrade"

5.1 Direct Replacement

5.2 Supply Chain Value-Added Services

• Fast Delivery: Standard 4-6 weeks; urgent orders compressible to 2 weeks.
• Cost Optimization: 20%-50% BOM cost reduction.
• Agile Customization: Non-standard capacitance, special voltage, and mounting configurations supported.
• One-Replaces-Many: Dual-chip structure enables a single part to replace multiple series/parallel configurations.

6. Market Track Record: Validated by Fortune 500 Customers

• GE Healthcare — Successfully replaced Murata DHS and Vishay 715C
• ABB — Replaced Vishay 715C for SF6 breakers
• Nikon / Konica Minolta — Replaced original AVX/Murata models
• Johnson & Johnson / Baker Hughes — Medical and exploration equipment

HVC's replacement solutions have passed the world's most stringent testing protocols, making it one of the most experienced domestic HV ceramic capacitor replacement manufacturers in the industry.

7. Conclusion: Building a Win-Win Supply Chain Partnership

Choosing HVC means higher supply chain security and a more competitive cost structure.
