Thanks for your comments NickS.
Really, this problem is really directed at fault analysis type people. People that have experience with electronic device operation outside of specification, not the reverse.
I really do appreciate everyones efforts.
Won't I don't appreciate is negative...
keep to 1206 and at minimum 0806 footprints
OK, I also have a footprint minimum. 1206 is what I am designing with, only due to the substrate it is going onto.
I tried using resistors, like a 1/16W and I could crank it up to 1W and yes, there was smoke, but it was still in-circuit...
Steve,
It aint a coffee machine! It was just an example.
My application does not get hot, no.
I want to control the burn-out electronically. Magic smoke is ok. We like magic! At 50mA, I don't think there will be much magic though :(
Cheers (and thanks for replying)
Hi Steve,
Thanks for your feedback but maybe Im still not clear enough.
I have a high consumable good. Say its one of those Nestle Nespresso capsules. You have a very small circuit on the capsule that:-
1) Lets the coffee machine know the size of the capsule,
2) Lets the coffee machine...
Yeah, high volumes!
Think of it as an electronic expiry indicator! (Patent Pending :) ) Once the "consumable" product has been used too many times, a component "blows" to indicate that you need to use a new "consumable" product. And, NO, its not to take advantage of warantees.... thats...
Thanks for your responses thus far.
I may need to elaborate a litte.
I really can't use a Fuse, and need to use something very small (equal to or less than 1206 size). So, please do not suggest a Fuse. Plus, a Fuse costs too much. My design is less than $1 already and I want to keep the...
Hi chaps,
I am wanting to make a circuit that I can "blow" on purpose - think of it as an expiry mechanism. I don't want something to reset (non-reset type fuse).
I was just thinking I could use an LED and drive the current high, but Ive noticed that the LED is still in-circuit after...
