Class II dielectric materials have a high dielectric constant and a small variation in capacitance with temperature (temperature range -55 ℃~+125 ℃, capacitance change rate ± 15%).
High cost-effectiveness, balancing performance and cost.
Application:
Widely used in consumer electronics (such as smartphones, tablets, smart wearables), power modules, audio circuits, and other scenarios that require medium precision and cost.
(3) X5R type
characteristic:
Similar to X7R, but with a narrower temperature range (-55 ℃~+85 ℃), a capacitance change rate of ± 15%, a higher dielectric constant, and a larger capacity.
Application:
Suitable for scenarios with high capacity requirements but narrow temperature range, such as power filtering, coupling circuits, and LED driver power supplies.

3. High capacity MLCC
characteristic:
By increasing the number of ceramic layers and optimizing electrode design, larger capacitance values can be achieved (e.g. 0805 size can reach 100 μ F, 1206 size can reach 220 μ F).
Balancing miniaturization and high capacity to meet high-density mounting requirements.
Application:
Suitable for scenarios that require large capacity energy storage, such as power backup, energy recovery, audio amplifiers, and industrial power modules.
4. Flexible electrode MLCC
characteristic:
