Does HVC offer low-inductance variants for high-frequency applications?

Yes — HVC Capacitor provides purpose-built low-inductance (low-ESL) variants across its product lines specifically optimized for high-frequency switching, RF power, and fast-pulse applications where parasitic inductance directly impacts circuit performance and efficiency.

Technique #1: Internal Electrode Geometry Optimization

Standard disc capacitors use radial electrode patterns that create significant current loops. HVC's low-inductance variants employ:

* Concentric electrode rings minimizing enclosed magnetic flux area

* Multi-terminal feedthrough designs canceling mutual inductance

* Shortened internal current paths reducing total loop length

Technique #2: Terminal Construction

* Flat ribbon terminals replacing round wire leads (reduces self-inductance by ~30%)

* Direct solder-pad interface eliminating lead wire entirely for surface-mount options

* Parallel terminal arrangement creating opposing current paths with partial cancellation

Technique #3: Material & Process

* Lower-loss dielectric formulations allowing thinner substrates (shorter current path)

* Precision laser-trimmed electrode patterns optimizing current distribution
