Small part, huge comment war
Extreme 220GHz+Broadband Silicon Capacitor X2SC 0201M 22nF BV11
A tiny part with a giant price tag has commenters laughing, squinting, and asking if it’s basically magic
TLDR: Murata unveiled a microscopic part for ultra-fast communications that packs unusual performance into something almost dust-sized. Commenters were far more animated about the price, the hilariously bare-bones diagram, and whether this fancy component is genius engineering or overkill in tiny form.
A new Murata capacitor — basically a tiny electronic part that helps control and smooth signals — landed with a spec sheet so intense it reads like it wants an action movie trailer. We’re talking a speck-sized component built for super-fast communication gear, bragging about working across an absurdly wide range and surviving extreme heat. On paper, it’s a serious bit of engineering. In the comments, though? Absolute chaos.
The biggest mood was a mix of awe, sticker shock, and nerdy comedy. One commenter dropped a DigiKey link and deadpanned that it costs “a mere 2.40 euros each!” for a part so small you could probably lose ten of them just by blinking. That instantly turned the conversation into a classic internet subplot: is this a miracle component, or an expensive grain of sand for people with very specific problems?
Then came the hot take: why does this even need to exist? One commenter wondered if you could just fake it with PCB traces, basically challenging the whole premise of the product. Others were less interested in the engineering debate and more obsessed with the comedy gold inside the datasheet itself, especially the gloriously underwhelming block diagram, which got multiple laugh-out-loud reactions. And in a delightfully niche twist, one person praised the rare sight of using nF instead of the usual confusing ways to write capacitance. Yes, even the units sparked feelings. Peak comment-section energy.
