Post by Externet »

Greetings.
It may work for the benefit of the few of us left...

Am looking for ICs
- 2 pcs 4077 CMOS gates trough hole,
- 2 pcs 4070 CMOS gates trough hole.

What do you need ?

Externet,

I'm working on a ATX power supply, that I need some 1000uF 16V 105C Radial through hole Capacitors.
But because parts are crammed in so tight.
I need the Capacitors to be small in size.
10mm in diameter by 20mm in height.

If your still looking for those IC's.
Would you be interested in a trade?

I know I have some {NOS} IC's.
And a few board pulls.
(1) ECG4070B
(10) SCL4070BE

(1) {RCA} CD4070BE

Hi Tzap.
Found only 5 in my bin (some used, some played with) but should have more if you do not mind pulled from miscellaneous boards by the time I mail them to you. My stupid caliper has no metric; but reads 0.4" diameter and 0.82" length. How many do you want ?
Send your mailing address on personal message.
Got the ICs I was after, thanks.

Hey, Externet....

Need too make sure the size is right.
Grab a Ruler that is in Inches.
Measure the Diameter of the Capacitor.
I need it to be 7/16 or smaller.
The Height can be 15/16, or slightly higher, or lower.
The Diameter is the important dimension, since the space on the PCB It has to fit is really tight!

So,
0.4357" (~11mm) x (around) 0.9375"(~24mm), 1000uF 16V 105C Radial. Yes, I know you said 10x20, but that's the conversion to the above fractions.
Here's a handy chart: https://printerfriend.ly/math/mm-to-inc ... heatsheet/
Don't have any, but it looks like Externet does.
Hey, what do I know?

Hi.
Ruler in inches ? The caliper is in inches !
0.4" diameter as I have is 10.16mm ; a frog's hair over 10mm you asked and want ! 7/16" you say now is bigger = 0.4375" = 11.12 mm ! :grin:
0.82" length as I have is 20.8mm ; a couple of frog hairs you asked and want ! 15/16'" you say now is bigger = 0.9375" = 23.81mm ! :grin:

:?

Okay,

I think the diameter is a hair big, but I think I can make it work. :)

I'll PM you my address.

??
Requested 10mm diameter.
10mm = 1cm
1cm / 2.54 = 0.3937in
So 0.4in with variation in (mostly) blue heat shrink thickness, and temperature of aluminum can of cap is
exactly as requested.
7/16in (from later post) leaves plenty of space.

Cheers,
Dale Y

Okay.....

I received the capacitors from Externet.

Thus, went ahead and replaced the two 1000uf 16V Cap's in the power supply.
It was a tight fit, but I got them in. :)

Here's a picture of an old Cap, and one of the Caps Externet sent me.
caps.jpg
The one on the left is the old cap.
6mm diameter x 20mm tall.
The one on the right is the replacement capacitor from Externet.
10mm diameter x 20mm tall.

As you can see, the old cap is about 4mm smaller in diameter than the replacement capacitor.
Thus, why I was so concerned about the physical diameter of the replacement capacitors.
:lol:

Well the power supply is working now, just need to do some testing on it too make sure it will hold up under load.
