Jumpers or low-ohms resistors in SOT523?

Folks,

Is a SOT23 "shorting device" available at a mainstream distributor? What would it be called? Pretty much like this but in SOT523:

It's a situation similar to what Phil recently had, there ain't enough volts. In my case a moocher winding on a 5V switcher. The load the client has on the +5V may be much lower than anticipated. The switcher then goes into pulse skip made and there isn't enough energy left to keep the -4V at -4V. I had a BAV199T in there to drop from -5.2V to -4V but it sags to less than 3V with the pulse skip. So I need a SOT523 with pins 1 and 2 shorted or low-ohms. Whether pin 3 is involved won't matter because it's a no-conect in the circuit.

Worst case yes, but automated board fab places frown upon such kludges.

Start with an NPN transistor and make your own!

The phssst ... *POOF* method is not easily ECO-releasable :-)

for sot523 is should of course be 0402, the pads are on the small side but the pitch is correct so I'd think that it could be automated

jumper do exist:

Nah, just buy some costly SOT523 device at a chineese brooker...

Guarenteed to be a fake and you'll have some chances to have what you're looking for (a dead short), indeed.

Thanks,

It can be automated but it's really frowned upon.

Shazam! Thank you. DC123 is exactly what I was looking for. It's weird that they use a domain for the island of Tuvalu without having any presence there. Looks like they have a sales outfit in Georgia:

Maybe it's a tax thing...

They might just have picked it because they missed getting the .com.

Looks like their actual headquarters is now in Georgia (the US one, not the European one) but it used to be in Orange County (the California one, not one of the several others).

More likely they want to go Hollywood.
