Are HVC components suitable for Tesla coil and high-frequency resonant circuits?

Yes — HVC Capacitor offers specialized product variants optimized for Tesla coil, solid-state Tesla coil (SSTC), DRSSTC (Dual Resonant Solid State Tesla Coil), and general high-frequency resonant converter applications operating from 50kHz through several MHz.

Primary Tank Capacitor	High current, moderate voltage, low ESR/ESL	HVCD-N750 or HVCT8G-N750	DF <0.02%, Q >5000 @ 100kHz
Circuit Element	Tesla Coil Requirement	HVC Optimal Product	Critical Spec
Secondary Base RF Ground	Very high voltage, ultra-low capacitance	HVCT8G-HighFreq Variant	Cj < 2pF, VRRM > peak secondary
Top Load Capacitance	Adjustable, stable value	HVCD-Adjustable Disc	N750 material, no aging
Gate Drive Isolation	Fast switching, low coupling	HVD-Fast Recovery	trr < 40ns, low Cj
Current Sensing/Shunt	Wide bandwidth, non-inductive	HVR-LowInductance Flat	Non-inductive, flat response to 10MHz+

For Tesla coil primary tank circuits operating at 100kHz – 500kHz, HVC recommends N750 dielectric material over N4700:

Parameter	N4700 (Standard)	N750 (HF Optimized)	Why N750 Wins Here
Dissipation Factor @ 100kHz	0.1% – 0.2%	<0.02%	10x lower losses
Q-Factor @ Resonance	2,000 – 5,000	5,000 – 15,000	Sharper resonance peaks
Self-Heating @ 500kHz PRF	Significant	Minimal	Sustained high-power operation
Microphonics	Very low	Extremely low	Cleaner waveform, less noise
Best Frequency Range	DC – 100kHz optimal	50kHz – 10MHz optimal	Matched to Tesla coil band

Note: N750 sacrifices some ultra-high-voltage capability (typically maxes at 30kV vs N4700's 100kV+) but delivers dramatically superior high-frequency performance. For DRSSTC primary tanks below 30kV, N750 is strongly recommended.
