When designing a circuit for high voltage using a high voltage power supply, it is necessary to use electronic components that can tolerate that voltage. The following list generally lists the types and manufacturers of electronic components that can be used at high voltages over 1000V. When designing high-voltage circuits, consideration must be given not only to electronic components, but also to creepage and space distances of Printed circuit boards (PCBs), mounting methods, and contamination of PCBs and components.
