"They're $14.50 each! Neither Digi-Key nor Mouser has them in stock, and quote a 25 week lead time. Digi-Key does have a 50 V version available today, but that will set you back $36.54."
I had no idea that the low leakage MLCC X7R dielectric capacitors are so costly!! That is crazy!! What makes these caps so costly and difficult to get any idea? Due to precision manufacturing process cost?
Btw...I never came across suggestions of using capacitor to increase battery life. Thanks for the tips that I should not think about that option even if somebody is suggesting that. Now another thought that comes to mind...we keep some small value capacitors as filters, decoupling capacitors and sometimes we use those abundantly if board space permits, without optimizing as needed. I take a lesson that I should be cautions to make optimal usage of caps in the battery powered circuits.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
