Product type
Disc ceramic capacitors are passive electronic components that store and release electrical energy in a circuit. They are made from a ceramic material that acts as a dielectric, sandwiched between two conductive plates. These capacitors are known for their stability, low cost, and reliability, making them a popular choice in various electronic applications.
| Capacitance range | 1 pF to 100 µF |
| Voltage rating | 6.3 V to 1000 V |
| Dielectric material | Class 1 (C0G/NP0) and Class 2 (X7R, Y5V) |
| Temperature coefficient | ±10% to ±20% |
| Tolerance | ±5% to ±20% |

When selecting disc ceramic capacitors, consider the capacitance value and voltage rating required for your application. It's important to specify the dielectric type based on thermal and voltage stability needs. Additionally, check the tolerance and temperature coefficient for your circuit's performance requirements. Quantities can vary based on project needs, so be clear about your order size when requesting a quote.

Class 1 dielectrics offer better stability and lower losses, while Class 2 dielectrics provide higher capacitance values but with more variation in capacitance with temperature and voltage.
Yes, disc ceramic capacitors are suitable for high-frequency applications due to their low equivalent series resistance (ESR) and inductance.
Disc ceramic capacitors have a long lifespan, often exceeding 10 years under normal operating conditions.
No, disc ceramic capacitors are non-polarized and can be connected in either direction in a circuit.
The right capacitance value depends on the specific needs of your circuit, including frequency response and load requirements.
Key factors include temperature, voltage, frequency, and the specific dielectric material used.
