Y2 cap legs offset

[Faringdon]

Hi,
For the VY2152M29Y5VS63V7 Y2 cap, the datasheet doesnt say what the "y direction" pin spacing is?

Do you know?

[Matt-Brown]

You mean lead spacing?
It is right on the datasheet

7.5MM

It's bleedin obvious from the datasheet, all you need is pin pitch (as Matt-Brown) says, and T_max from the mechanical drawing. Isn't it about time that you learned to read a datasheet Treez?

You shouldn't be mounting Y caps that close to other components anyway.

[Faringdon]

Thanks, but 7.5mm is the main pitch...the pitch orthogonal to that is not stated.........for the page 2 one.

The distance between two points is a line of definite length.  The fact that the body of the capacitor does not seem aligned to this line is generally irrelevant, unless extreme OCD is pushing you to put the TH pads at an angle so the body of the cap looks nice and neat.  In that case, I think you'd have to guesstimate from the drawings or samples and understand that the 'twist' is not specified or guaranteed.

Why don't you ask Vishay cdc@vishay.com and give them shit for their crappy datasheets and 17-digit part numbers?
"15th digit of the clear text code number to be completed with the packaging code." OK, info is missing from the datasheet.
They offer at least 3 lead-bending options - straight, kinked, (vertical) inline kink, coating extension etc.

Caution the vertical lead bent ones can arc to whatever is next to them, not recommended.

Again, looking at the mechanical drawing for the straight lead package, T_max still covers it. It doesn't matter whether the pins are in-line (package skewed) or not, the package will never be wider than T_max. Whichever cock-eyed way you chose to interpret it, the pin pitch is still the distance between the pin centres!

If Vishay really and truly didn't put the information you're looking for on the datasheet it's almost certainly because they couldn't imagine anyone ever needing the information. Obviously, nobody here knows. So, if you really and truly have a good reason to know (which I won't ask about) then you'll need to contact Vishay.

One alternative is to buy some and measure them.

Another alternative is to convince yourself that you don't need to know and spend your time on something more productive.

Nope, Vishay datasheets commonly have missing specs and dimensions. Just use another brand if you're in a hurry.

If we define the lead spacing F as our X axis, then I think OP is asking what the Y-axis spacing is. A valid question for certain types of capacitors. But of course, this is treez we're talking about, who seems categorically incapable of figuring out anything that's not spelled out as you would for the kids on the short bus...

The capacitor part number provided ends in -3V7, meaning: bulk pack, inline kinked leads, 7.5mm spacing.

Inline kinked.

Inline.

In a line.

The same line.

Y = 0.

Look at the drawing on page 2 at top right. Side view of a cap. See the legs? They're in one line.

So you design your footprint to have two holes, 7.5mm apart, on the same line.

If your actual question isn't the hole positions, but the width of the part itself, that's already been explained.

You're clearly quoting some other datasheet, not this one. That quoted sentence does not exist in this datasheet, this series has only two lead options (straight and inline kinked), and there's no ambiguity as to how to assemble a part number.

I got that from Mouser which links to an old cached datasheet Document Number: 28535, Revision: 18-Oct-11
The latest is Revision: 28-Jan-2022. Mouser Canada links to Vishay. Must've been Mouser USA search results.
For the straight leads part, missing is the lead offset spacing but that option is special order anyway, and clashes with the tape and reel drawings of the leads on the datasheet.

Sometimes I will work backwards and see what distributors offer, and what the 3D model shows, to decipher part numbers and dimensions. Lately I find something critical is always missing when making a footprint. Vishay resistors were on my hit list last week and who's got the time to let them know and argue why they omitted dimensions/specs that other manufacturers have.

I find kinked leads are a problem with thick parts because the leads splay out and then back in (to keep it inline) but the leads like to arc to adjacent parts- which is not discovered until transient testing the product.

Why were you going to Mouser at all, when the link to the datasheet on the Vishay website was right in the first reply?!? (And the OP posted a link to Digi-Key, which in turn also links to the current Vishay datasheet.)

Well you might have better luck if you used the current datasheets, not old ones. And I guess they probably do listen to customer feedback, since they clearly have updated the datasheet over time.
