This video from Würth Elektronik elaborates on clearance and creepage distance and solid insulation materials. Many applications of fire are productive and warming. Fire can be a real risk if the components on pcb has not been selected correctly for high voltages. In some circumstances, incorrectly selected components can create Transient voltage, which could cause Read the original post at Creepage and Clearance of...

Full paper download The challenge of Space operating components increases from one year to another. This paper study capability and physical mechanisms of microswitch manufactured by PETERCEM to operate at different temperature ranges (cryogenic, ambient and a transition temperature from cryogenic to ambient). The paper was presented by Manuel Sánchez Ruiz, Alter, Sevilla, Spain at the 4th PCNS 10-14th September 2023, Sønderborg, Denmark as paper No. 3.3....

Full paper download Designing medical implantable devices for high reliability is crucial for a variety of reasons. To ensure that used components are manufactured to meet medical implantable application standards, proper screening and high reliability design is required. This paper elaborates on requirements for MLCC ceramic capacitor to meet such medical standards. The paper was written by Victor Lu and presented by Samuel Dowrick,...

Full paper download The paper compares two ways to increase the robustness of assembly against ECM electrochemical migration. In the paper, we underline some challenges in gap cleaning. We describe state-of-the-art methods of cleaning process control and diagnostics, which move the cleaning process from randomly controlled to very safe with stable results. The paper was presented by Vladimir Sitko, PBT Works s.r.o., Rožnov pod...

This video by Dr. Ali Shirsavar from Biricha is a follow up from a previous video on inductor behaviour in a switching power supply with practical demonstration of inductor EMF electromotive force. In one of our previous videos here: Inductor Behaviour in a Switching Power Supply we explained the action of an inductor in a switch mode power supply. This is the second part...

This article is based on Murata application note on 3-terminal capacitor use to suppress EMI radiated emission noise and improve conducted immunity. Noise-control techniques are becoming increasingly important due to high-speed operation of ICs and electrification of automobiles. This application note introduces examples of using the 3-terminal ceramic capacitor as a filter (feed-through connection) for radiated emission and conducted immunity. Radiated Emission In the recent...
