Does HVC offer gold or silver termination for ceramic capacitors?
Yes — HVC provides both gold-plated and silver-plated termination options for its high voltage ceramic disc and doorknob capacitor product lines, selected based on application-specific requirements:
| Termination Type | Material | Contact Resistance | Typical Application | Cost Factor |
|-----------------|----------|-------------------|--------------------|-------------|
| Silver (Ag) | Silver epoxy/solder | <10 mΩ | Standard industrial, general purpose | Baseline (1.0x) |
|---|---|---|---|---|
| Gold (Au) | Gold flash over nickel barrier | <5 mΩ | Medical implants, aerospace, high-reliability | Premium (~1.8-2.2x) |
Gold termination advantages:
* Superior oxidation resistance for 20+ year field life in humid environments
* Lower contact resistance critical for precision voltage divider networks
* Enhanced wire-bondability for hybrid circuit integration
* RoHS-compliant gold plating process (no cyanide)
Recommendation: For most smart grid, laser, and RF power applications, standard silver termination provides excellent performance at lower cost. Reserve gold termination for medical implantable devices, space/military programs, or ultra-long-lifecycle (>25 year) infrastructure deployments.
