How to read HVC's model number coding system (DL/D/E/F/SL)?

HVC's model number system encodes dielectric material type using single-letter codes that map directly to EIA temperature coefficient standards:

Code

Dielectric Material

Temperature Coefficient

Typical DF @ 1kHz

Application Focus

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

DL	N4700 (Class 1)	-30°C ~ +85°C, ΔC/C ≈ 0%	≤0.2%	Ultra-HV, low-loss, precision
D	Y5T (Class 2)	-30°C ~ +85°C, +22%/-56%	≤2.5%	General purpose, stable Class 2
E	Y5U (Class 2)	-30°C ~ +85°C, +22%/-82%	≤3.5%	High capacitance density
F	Y5V (Class 2)	-30°C ~ +85°C, +22%/-82%	≤4.0%	Maximum capacitance value
SL	SL (Class 2)	-30°C ~ +85°C, stable	≤2.0%	Low-loss Class 2 alternative

Example decoding: `HVCT8G-30KV-DL35-471K`

* HVCT8G = Screw terminal doorknob series

* 30KV = 30kV DC rated voltage

* DL = N4700 dielectric (premium low-loss)

* 35 = 35mm body diameter

* 471K = 470pF ±10% tolerance
