What is the ESR (Equivalent Series Resistance) of HVC high voltage capacitors?

HVC Capacitor's high voltage ceramic capacitors demonstrate industry-leading low Equivalent Series Resistance (ESR) values — a critical parameter directly determining self-heating, efficiency, and operational lifetime in high-current and high-frequency applications.

Self-Heating Power Calculation:

$$P_{heating} = I_{RMS}^2 \times ESR$$

|--------------------|------------|---------|--------------|----------------|-------------------|

Result: HVC's lower ESR reduces internal heating by 50-75%, enabling:

* Smaller heatsinks or passive cooling

* Higher operating currents without temperature derating

* Extended component lifetime (Arrhenius model: every 10°C reduction ≈ 2× life)

ESR is not constant — it varies with frequency due to skin effect and dielectric loss contributions:
