Capacitor technical knowledge, principles and fundamentals
Every switching transition pushes current through the loop between the switch and its decoupling path. That loop has inductance, and inductance turns a change in current into a voltage: [...]
A solar inverter asks its DC-link capacitor for something harder than a peak rating. It asks for the same modest duty, repeated every day for twenty-five years. What separates a [...]
Choosing between an MLCC and a film capacitor comes down to one question: is this position about density and frequency, or about voltage, current and life? MLCCs win the first [...]
An 800 V SiC inverter pushes its DC-link film capacitor harder than any IGBT-based design did. The bus voltage climbs to the 800 V class, and the switching frequency rises [...]
Choosing a DC-link film capacitor comes down to four numbers: voltage rating and derating, ripple current, ESR, and the size that fits your inverter. Get these right and the capacitor [...]
eVTOL powertrains are rewriting the requirements for DC-link capacitors. Electric aircraft need high ripple current, low inductance, low weight and aviation-grade reliability from the film capacitors that sit on [...]
Open any box of used power supplies and you will find the same green rectangular part stamped with a code like 2J105J. The CBB22 capacitor value printed on its [...]
What Is a CBB Capacitor? A CBB capacitor is a metallized polypropylene film capacitor — a non-polarized capacitor that uses polypropylene film as the dielectric and an ultra-thin metallized [...]
Learn everything about film capacitors - types, working principle, key parameters, applications and selection tips. A complete guide by Xuansn, a film capacitor manufacturer.
What Are the Common Capacitor Types? A Complete Selection Guide Capacitors may look similar from the outside, but in practical electronic design, different capacitor types serve very different purposes. [...]
