MLCCs are the most common type of capacitor out there. Almost every single electronic device uses MLCCs in a multitude of applications. We all know what MLCC stands for (multilayer ceramic capacitor), but do you know how they are made? What are the different types and how to choose from among all the...

Advantages and disadvantages of MLCC downsizing are discussed in AVX technical papers written by Frank Hodgkinson and Maureen Strawhorne. As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required.

Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, an SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators.

Metallized Polypropylene Film Capacitors For example, consider two of the main purposes of capacitors in electric vehicles: to prevent ripple currents from reaching back to the power source, and to smooth out DC bus voltage variations. Capacitors are also vital in protecting semiconductors – originally thyristors, but now usually IGBTs.

High Voltage MLCCs Arc-Over Prevention

In applications in which energy conservation is critical, such as wind or solar inverters or electric-vehicle (EV) powertrains, distributing power at high voltage can help to reduce I2R losses. The DC link supplying the inverter can be 3 V to 400 V in an EV application, for example, or even higher for wind or solar-power conditioning. However, high operating voltages like these bring additional safety challenges not only for end users but also for components — even those with a suitable voltage rating stamped on the case.
