Aplicação de métodos experimentais alternativos para avaliação da retardância à chama em madeiras
… 60695-2-13, and the mass loss cone calorimeter (MLCC) test, in accordance with ASTM E2102-08. The results demonstrated that the surface application of the flame retardant did not significantly reduce the peak of heat release rate and the total heat released from the tested materials, counter to …

Modeling and Analysis Methods for ESD and EMI Problems
… to analyze the acoustic noise created by MLCCs on a PCB. A simulation model for the PCB vibration modal response is built to analyze the harmonic response of the PCB excited by the capacitor. Total response is obtained by multiplying the measured power noise spectrum on the MLCC with the …

Flex Cracking and Temperature-Humidity-Bias Effects on Reliability of Multilayer Ceramic Capacitors
Multilayer ceramic capacitors (MLCCs) are known to be susceptible to cracking when subjected to excessive printed circuit board (PCB) flexure, which is called "flex cracking". The bending of the printed circuit board causes stresses to be transmitted through the solder fillets to the surface mount …

Soft Switching Control and Loss Analysis for High Frequency Power Converters
… Class II multi-layer ceramic capacitors (MLCCs) promise even more compact and efficient power conversion. Ferroelectric Class II MLCCs have been widely applied as the DC-link capacitor or resonant capacitors in the WBG-based power converters. However, in literature, little attention has …
