Temperature range for use |
-55℃~+125℃或-55℃~+85℃ |
Temperature range for use |
-55℃~+125℃或-55℃~+85℃ |
Characteristics and Applications
No external sealing layer, suitable for surface mounting;
The medium is Class II ceramic, with a high dielectric constant and a large capacitance to volume ratio of the capacitor;
Each batch of products undergoes 100% temperature shock screening and high-temperature electrical load screening;
Suitable for bypass, filtering, low-frequency coupling circuits in various military electronic equipment such as weapons, ships, aviation, and aerospace, or circuits with low requirements for loss and capacitance stability.
