A series of stacked-ceramic capacitors specially designed for SMPSs features the thermal per-formance of conventional ceramics without their mechanical drawbacks, enabling higher reliability and operating temperatures. number of applications require elec-tronics that can survive and operate in extreme environmental conditions.
The most common design of a ceramic capacitor is the multi layer construction where the capacitor elements are stacked as shown in Figure C2-70, so called MLCC (Multi Layer Ceramic Capacitor). The number of layers has to be limited for reasons of the manufacturing technique. The upper limit amounts at present to over 1000.
KYOCERA AVX stacked ceramic capacitors are supplied with lead frames for either thru-hole or surface mount assembly. The lead frames act as stress relief for differences in coefficients of expansion between the large ceramic chip (10 ppm/°C) and the PC boards ,and are offered in both horizontally and vertically stacked configurations.
For example, combining two 220 µF T54 series parts results in a 450 µF assembly. There are also other mechanical advantages of using the stacked capacitor terminations. They include better heatsinking and more robust shock and vibration performance.
