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 DPA, 100% temperature shock screening, high-temperature electrical load and room temperature moisture screening;
Suitable for bypass, filtering, low-frequency coupling circuits in various military electronic devices or circuits with low requirements for loss and capacitance stability.
