Package Generator - E-Cap

Tasse500 — Sat, 03 Feb 2024 14:47:43 GMT

Hi,

I am trying to generate an E-Cap package with the Package Generator.

I had a datasheet where D (Lead Span) and D1 (Terminal Gap) were given so I chose L (Terminal Length) as the optional dimension. However, when I provide the dimensions the values for L seem to be calculated wrong and the tool prevents me from adding the package because Lmin is greater than Lmax.

The tool is doing

Lmin = (Dmin - D2min)/2; Lmax = (Dmax - D2max)/2

I belive it should be

Lmin = (Dmin - D2max)/2; Lmax = (Dmax - D2min)/2

I can work around it by changing the values slightly, but I would suppose to change the calculations.

Thanks

Hi @Tasse500,

Could you post the specific Datasheet? Keep in mind that the letters in the datasheet don't always line up with what's specified in the Package generator, make sure that that what the quantities represent is the same on the datasheet as it is on the package generator.

Let me know if there's anything else I can do for you.

Best Regards,

I have this exact same issue, the outer dimensions for the legs should be set by D, unless I'm misunderstanding the package figure shown by Fusion. Settings for package generator, the output with the error measurement shown, and the datasheet for reference.

Hello @SeanDBA,

I hope you're doing well. So the thing that is annoying is that there is not standardized format for datasheets. In this case what the datasheet defines as L and what Fusion defines as L is different. So you are going to have to be careful and map the letters in the datasheet to the letters in Fusion and make sure the correct values go where they need to go.

Let me know if there's anything else I can do for you.

Best Regards,
