CT41 - Military multilayer ceramic capacitors
- 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 devices or circuits with low requirements for loss and capacitance stability.
