ESP Function	Recommended HVC Product	Key Specification	Why This Choice
DC Bus Filter/Smoothing	HVCT8G-DL (N4700) or HVCD-DL	20kV – 80kV, 1nF – 100nF	Low DF prevents self-heating in 24/7 operation
Voltage Multiplier Stack	HVD-Multiplier Series	20kV – 60kV output	High PDIV immunity in dusty/humid environments
Feedback Divider Network	HVR-GFP/GXP	10MΩ – 10GΩ, ±0.5%	Stable ratio for closed-loop control
Bleeder/Discharge Resistor	HVR-BSP/BOP	100MΩ – 10GΩ, 25W – 100W	Safe energy discharge when powered down
Current Limiting/Protection	HVR-Tube (Custom)	Per fault current calc	Non-inductive, surge-withstanding

ESP installations present uniquely challenging operating conditions that HVC products are specifically engineered to withstand:

Environmental Factor	ESP Challenge	HVC Mitigation
