Abstract (Executive Summary)

Screw-terminal (doorknob) HV ceramics are critical in physics, grid, CT/X-ray, and lasers. Murata’s DHS EOL (2018) tightened supply. HVCA (Dean Tech) markets HT / NX / JX, but buyers often see 16–24 week leads, brand markup, and OEM-limited support.

HVC is an integrated factory: solid copper terminals, internal dual-chip construction, and N4700 Class I. Qualified at GE, Siemens, ABB, J&J—this paper argues HVC is the strongest HVCA screw-terminal replacement on technical and commercial grounds.

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

In screw-terminal HV caps, “Western brand” does not always mean in-house manufacturing.

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

HVCA NX (30–40 kV) and JX (large custom) largely follow a reseller / private-label pattern.

• Limited deep R&D: Non-standard needs (e.g. >50 kV) are constrained by OEM capability.
• Cost stack: After logistics, brand, and distribution, end price can exceed 3× ex-factory.
• Schedule risk: OEM reliance → leads often 16+ weeks or worse when logistics tightens.

1.2 HVC Capacitor: Returning to the Essence of Manufacturing

HVC runs full-process production in-house.

• Process control: Powder through sintering, metallization, epoxy—owned under one roof.
• Lead time: Typically 4–6 weeks; urgent cases about 2 weeks.
• Pricing: Direct factory path often saves 30–50% vs. layered brand chains.

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

Beyond price, design choices explain why tier-one OEMs stay with HVC vs. relabeled HVCA lines.

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

About 40% of screw-terminal field failures are terminal pull-off or stripped threads.

• Typical OEM stack: Silver-on-ceramic or iron caps—higher loss, rust risk, silver migration in humidity, weak under >3 Nm torque.
• HVC: Solid copper terminals—better heat spreading than iron; anchor design rated to 4.5 Nm torque for production drivers.

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

Single monolithic stacks hit a wall near 40 kV before PD and porosity bite.

• HVC: Dual-chip internal series splits stress—production at 50–100 kV screw types (e.g. 50 kV 8000 pF N4700) with margin HVCA rarely matches.

2.3 Material Foundation: True N4700 (Class I) Dielectric

Some cost-trimmed lines blend Class II (Y5U/Z5U)—D.F. can approach 1% and run hot in RF.

• HVC high-end: N4700 Class I—D.F. <0.2%, R_ins >200 GΩ; cooler in CT-style pulse duty, longer service life.

Chapter 3: Precise Benchmarking – HVC's Full Replacement Solution for HVCA JX/NX Series

Pin-to-Pin examples for HVCA JX and NX (see tables).

3.1 Replacing JX Series: 10kV-20kV Large Capacity/Custom Type

JX (JX5T…): HV PSU filtering—large C, often custom.

HVCA (Dean Tech) Actual Model	HVC Recommended Replacement Model	Specifications	HVC Technical Upgrades
JX5T3M802K10KV	HVCT8G-10KV-E-802K	10kV / 8000pF	Y5T; smoother drift vs. T3M.
JX5T3M103K10KV	HVCT8G-10KV-E-103K	10kV / 10000pF	Lower ESR; higher ripple current.
JX5T3M222K15KV	HVCT8G-15KV-E-222K	15kV / 2200pF	Creepage optimized for humid air.
JX5T3M472K20KV	HVCT8G-20KV-E-472K	20kV / 4700pF	Copper terminals vs. iron caps—better oxidation resistance.

3.2 Replacing NX Series: 30kV-40kV Ultra-High Voltage/Precision Type

NX (NX5T…): DHS-class use—CT, X-ray, grid.

HVCA (Dean Tech) Actual Model	HVC Recommended Replacement Model	Specifications	HVC Technical Upgrades
NX5T3M202K40KV	HVCT8G-40KV-DL-202K	40kV / 2000pF	N4700 + dual-chip; higher margin at 40 kV.
NX5T3M102K40KV	HVCT8G-40KV-DL-102K	40kV / 1000pF	Low loss (<0.2%) for HF lasers / accelerators.
NX5T3M472K30KV	HVCT8G-30KV-DL-472K	30kV / 4700pF	Medical-grade; 100% PD tested.
NX5T3M222K30KV	HVCT8G-30KV-DL-222K	30kV / 2200pF	High torque for automated lines.

Chapter 4: Elite Circle – Why Giants Choose HVC?

Field use at tier-one OEMs (examples):

• GE Healthcare — CT HV; qualified vs. Murata after long-term aging.
• Siemens — X-ray gens (BR/EU); 20 kV 3300 pF Y5T, 30 kV screw types.
• ABB / grid — breakers and HV test gear outdoors.
• J&J — surgical power modules; custom fit where space is tight.

---

Chapter 5: Conclusion and Commercial Value

Staying on HVCA alone often means brand premium plus long, less predictable lead times.

• Tech: Copper terminals, dual-chip, N4700 where it matters.
• Cost: Factory-direct—often >30% savings.
• Delivery: ~4–6 weeks standard; VMI available.

Rational BOM: source from the factory that actually builds the part.
