These parts are very simple to create in the new "V2013 Footprint Designer" and then save to FPX to share with others on the "Parts on Demand" (POD) website library vending machine.

They should only be built once by someone and then shared with the entire electronics industry.

I've seen a few crystal oscillators and a couple of filters with a similar kind package I think but I can't put my finger on any specific one at the moment.]]> Wed, 05 Sep 2012 00:23:41 +0000 https://www.PCBLibraries.com/forum/bourns-tbuca-series-pad-layout_topic541_post1655.html#1655 <![CDATA[Bourns TBU-CA Series Pad Layout : Oh, I didn't realize I hit...]]> https://www.PCBLibraries.com/forum/bourns-tbuca-series-pad-layout_topic541_post1654.html#1654 Author: Lars P M

Oh, I didn't realize I hit in between all existing foot prints ;-)

Actually Bourns has a series of different TBU components, e.g.

2-pin different pad size

http://media.digikey.com/PDF/Data%20Sheets/Bourns%20PDFs/TBU-KE_Series.pdf

4-pin, 2 rows by 2, different size

http://www.bourns.com/data/global/pdfs/TBU-DT.pdf

8-pin, 2 rows by 4, different size

This Bourns TBU-CA is a 3-Pin DFN but it's the first one I've ever seen with 3 pins in a row -

http://www.bourns.com/data/global/pdfs/TBU-CA.pdf

We will have to create a new component family template for this part, but in the meantime you can create the library part using the 2-pin DFN and add the middle pin in your CAD tool library editor. I would make the size of the middle pin the same size 0.05 mm annular ring larger than the lead size.

Are there any more of these 3-pin DFN parts out there? We do not like to create component families for unique one-of-a-kind package.

This request for a new component family belongs in the "Product Suggestions" Forum -

Hi Lars,

The datasheet says its a DFN package:- However the 3 pins are arranged different than this tool. so I probably would use the 2 pins DFN option and modify it for 3 pins. or just draw it yourself.. not sure if that helps Ouch

The TBU®

high-speed protector placed in the system circuit will monitor the current with

the MOSFET detection circuit triggering to provide an effective barrier behind which

sensitive electronics will not be exposed to large voltages or currents during surge

events. The TBU®

device is provided in a surface mount DFN package and meets

industry standard requirements such as RoHS and Pb Free solder reﬂ ow proﬁ les.

Anybody here having experience with the Bourns TBU-CA High Speed Protectors?

I think the datasheet description of the Pad Layout is a bit unclear.

What Component Category should be used to make the layout?

Thanks
