Key Features and Benefits
In PLC systems, high-voltage doorknob capacitors serve as indispensable "frequency selectors" and "insulation barriers" in the coupling circuit, addressing two core challenges:
- Withstand power line voltages from several thousand to tens of thousands of volts to ensure absolute safety for back-end communication equipment
- Achieve low-loss signal transmission within the carrier frequency range (typically 40-500kHz)
Our high-voltage door handle capacitors feature specialized ceramic dielectric and vacuum epoxy potting process that ensures:
- Stable insulation performance across voltage levels of 35-500kV
- Low equivalent series resistance (ESR) and low inductance (ESL) for excellent frequency response
- Exceptional temperature stability (±2% capacitance change from -40°C to +85°C)
- Long-term reliability in harsh environments
As a core component in the coupling circuit, our high-voltage door handle capacitors fulfill the dual duties of high-voltage isolation and high-frequency coupling, ensuring stable operation of PLC systems in various conditions.
