Inductor - can I use one greater than 10uH? - Mintyboost v3

[lee321987]

Is it ok to use an inductor greater than 10uH?
Perhaps it's ok to go a litter over, but not more than <insert value>?

The design process - including inductor calculations - can be found here: http://www.ladyada.net/make/mintyboost/process.html

Thanks. I read it, but it doesn't answer my question.
Assume the greater-henry inductor has equivalent resistance to the official one.

[adafruit_support_bill]

The inductor is part of a tuned circuit. Any significant variation is likely to decrease efficiency - if it works at all. You will note that half of the "process" page is about prototyping and testing. If you want to swap parts, be prepared to do a lot of testing and tweaking on your own before you get it right.

As it says in the FAQ:

Most components cannot be swapped, and must be used as indicated, even if they're difficult to find in your area. All documentation is on the site.

I can't provide any support or help to 'DIYer's because of the time and difficulty in debugging these projects. Please endeavor to work out your project on your own.

Ok, I understand. Thank you.

I noticed that the parts list for the MintyBoost (v2 & 3) specifies a 10uH inductor. However, the parts link to Digi-Key shows a 2200uH part. Which one is correct? I'm assuming the 10uH part is indeed the part in the kit, but can you clarify?

[adafruit_support_bill]

The partfinder page link actually shows two inductors, 2200uH and 10uH. The 10uH is highlighted, but it is easy to overlook because there is no image.

I fixed the missing image.

The image I used was that of the RLB9012, taken from the manufacturer website, so there shouldn't be copyright concerns.

Note I did hotlink the image, which probably is not a good long term idea...
