Capacitor value question

[Aurbo99]

Greetings

Capacitor marked 104M = 0.1uf +/-20% 50V good for the Grinch board? or too loose a tolerance? Green Ceramic Disk Capacitor

Totally non-critical...that part is fine.

Hi,

Monolithic capacitors are specified for the project, you could use Ceramic capacitors, however they are not recommended for the purpose.

Standard Ceramics 'should' work.

Thanks for the info.

Having a tough time locating such a common part..

Axial Ceramic 50V 0.1uF is monolithic? something new learned today! =)

I may just have to break down and make a purchase from Mouser after all.

I recieved my 6 free Allegro samples last Friday.. 3 days from request to my door. Enough for a single Grinch with 2 spare.

Had to slice up some 20pin dip sockets from wide base to fit the board.

RJ-45 sockets must have all been shipped to Australia or somewhere more exotic.. I cant find a single unit in Maritime Canada.

Resorted to cannibalizing a few dead NIC cards from my computer parts bin, enough to at least try a single 4 channel SSROZ board with the Grinch. But still short 28.

Only 3 Triacs could be found.. which may force my hand towards Mouser..
Only 3 BTA10-400B could be found 10Amp vs 8Amp.. not sure if the specs are good enough yet.. NTE5645e what I found.

Can I run a SSROZ board with only 3 channels installed on it?

NO 3023M's anywhere east of Montreal.. and nothing less than 3 bucks a chip.. Again looking to Mouser to save my project, .45each there.

Well its back to soldering.. Cheers

“monolithic” ceramic capacitor

A much more sophisticated design is called the “monolithic” ceramic capacitor. It offers much higher capacitance per unit volume. it differs from a standard ceramic in that it has three plates, and not two. The ceramic material acts both as dielectric and as encapsulant of the basic element. Electrodes are buried within the ceramic and exit only on the ends.

Capacitor lesson is over.

You can use 1,2,3 or 4 channels on the SSR, and load the PCB with that amount of components.
