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 devices or circuits with low requirements for loss and capacitance stability.
