Downsizing MLCCs Quiz

Quiz | Passive Components | MLCCs Downsizing Q&A with Murata | WorkBench Wednesdays

When downsizing multilayer ceramic capacitors (MLCCs) from larger case sizes down to 0201, there are several considerations. The first is supply chain availability. As customer designs get smaller, so do the requirements for the size of components like capacitors. Therefore, manufacturers like Murata are ramping up their production lines to accommodate smaller case sizes. Second are the design or technical considerations. For background on this topic, watch the following interview between Yang Jiang, Murata Product Manager, and James Lewis, element14 Presents host, as they discuss these considerations. Then watch the Workbench Wednesdays Episode, where James shows how the design considerations affect a 555-timer circuit.

Great companion of the interview and the Electronics Workbench episode.

MLCCs can be tricky to use properly and expensive to source, but they do have some excellent characteristics if you design for them properly.

Again I am astounded by my capacity for answering wrong.

Excellent content! Right now I'm starting to use 0402, maybe in some designs I'll downsize to 0201 if is require. I do manual soldering for almost all of my prototypes.

Need to include NP0 (as an Alternative nomenclature to C0G), X8R, minimization of inductance of capacitors by flipping it on it's sides.

Doubling. As the capactiance goes down, the frequency goes up.

While editing the video, I realized the main reason SimSurfing and the measurements differed. I made the assumption that the capacitor sees the full VCC voltage, it doesn't. I think it only sees about 2/3 of VCC, but I'd have to go look at the 555's internal schematic again to be sure.

I really like these capacitor quizzes, videos and essentials! Curious if muRata have something similar to Würth's Abc of Capacitors book, because I really liked the explanations from the muRata product engineer.

Sadly I missed how much it changed it capacitance with Vdd at 8 V. I heard a 35% figure and looked at the SimSurfing graphs but it was something different, so I'm guessing that you should have seen the more than halving in frequency? I should disclose that I was filling in the quiz as I went along the video, so my focus might not have been 100% at all time.

Some serious content presented on a lighter note. Thanks for putting a smile or two on my face today.
