Product type
High voltage resistors are passive electronic components designed to handle high voltage applications. They are typically made from materials such as carbon composition, metal film, or wire wound, which allow them to maintain stability and reliability under high voltage conditions. These resistors are essential in circuits where voltage levels exceed standard limits, ensuring safe operation and performance.
| Resistance range | 1 kΩ to 10 MΩ |
| Power rating | 0.25 W to 10 W |
| Voltage rating | Up to 10 kV |
| Tolerance | ±1% to ±10% |
| Temperature coefficient | 100 to 500 ppm/°C |
| Construction type | Wire wound, metal film, or carbon film |
When selecting high voltage resistors, buyers should consider the resistance value, power rating, and voltage rating to ensure compatibility with their applications. It is also important to specify the tolerance and temperature coefficient based on the precision required for the circuit. Certifications such as UL or CE may be relevant depending on the application, and buyers should inquire about minimum order quantities to optimize their procurement process.
