[经验] 如果你找不到你的MLCC,你为什么要看看KO-CAP

工程界的每个人都试图订购一种较高价值(≥0.1μF)的多层陶瓷芯片电容器(业内称为MLCC),他们最近痛苦地意识到常见价值的持续不足。
需求超过供应,MLCC产能恢复平价还需要一段时间。
那么你在此期间做了什么?
KEMET技术营销高级经理Wilmer Companioni(兼工程师!)可能会为您提供KO-CAP系列(他们的钽聚合物电容器系列)的解决方案。
它适用于每个人吗?
不,但鉴于正确的情况,它可能提供一个合理的选择。
Companioni最近在KEMET的在线教育资源工程中心的博客文章中概述了如何以及在何种情况下用钽聚合物取代MLCC可能对您有用。
是的,MLCC行业正在经历相当大的容量紧缩。
最后一次是这样的,我们又回到了'99  -  2000年的.COM日。
制造商正在投入产能,但这需要一些时间才能实现。
我知道对于处理线下情况的工程师以及不得不乞讨,借用和窃取零件的供应链经理来说,这是一种冷酷的安慰。
在这样的时代,工程师们无需进行大规模的重新设计即可探索新的选择和替代技术。
我不是妄想,当我正在寻找MLCC时,我也是一名工程师并且用钽销售我并不是我的心。
但是,作为工程师,解决问题就是我们所做的,这意味着做我们以前没有考虑过的事情。
与工程中的其他任何事情一样,决定从MLCC转到KO-CAP只是管理权衡的问题。
做出决定时必须考虑很多事情。
要了解从MLCC到KO-CAP的更多信息,请阅读完整的文章。
此外,Digi-Key的高级应用工程技术人员Robert Fay在Digi-Key技术论坛的帖子中提供了关于可能将MLCC Cap转换为Tantalum Cap的想法。

以下为原文


Everyone in the engineering community who has tried to order one of the higher value (≥ 0.1 µF) multi-layer ceramic chip capacitors (referred to by the industry as MLCCs) recently is painfully aware of the ongoing shortage of common values. Demand has outpaced supply, and it will take some time before MLCC production capacity regains parity. So what do you do in the meantime? Wilmer Companioni, Sr. Manager – Technical Marketing (and fellow engineer!) at KEMET may have a solution for you in the KO-CAP series (their tantalum polymer capacitor series). Will it work for everyone? No, but given the right situation, it may offer a reasonable alternative. Companioni outlines in a recent blog post in the Engineering Center, KEMET’s Online Education Resource, how, and under what circumstances, replacing MLCC with tantalum polymer might work for you.
Yes, the MLCC industry is experiencing quite the capacity crunch. The last time it was like this we were back in the .COM days of ’99-2000. Manufacturers are putting in capacity, but that will take some time to come up. I know that’s cold comfort for the engineers who are dealing with line down situations, and the supply chain managers who are having to beg, borrow, and steal parts. It is times like this that make engineers explore new options and alternative techniques without having to do a massive redesign.
I am not delusional, I was (am) an engineer too and selling me on tantalum when I’m looking for MLCCs isn’t exactly the way to my heart. But, as engineers, solving problems is what we do and that means doing things we haven’t previously considered. As with anything else in engineering, making the decision to go to KO-CAP from MLCC is just a matter of managing tradeoffs. There are a slew of things that must be considered when making that decision.
To learn more about going from MLCC to KO-CAP read the complete article here. Additionally, Robert Fay, Senior Applications Engineering Technician from Digi-Key, provides thoughts on potentially crossing an MLCC Cap to a Tantalum Cap in his post on the Digi-Key Tech Forum.
