who manufacturers gold plated Jfets in Philippines ?

which semiconductor based company manufacturers gold plated jfets to Linear Systems in Philippines?

These are made in California by Linear Systems. I can only presume if you want originals then buy through a distributor from Linear Systems.

Then why is it marked as Philippines on it?

 

[JonSnell Electronic]

Probably a fake. Why not ask Linear Systems, they are only an email away.

I guess a fake would print a more "prestigious" Country (USA/Japan?Germany) to boost sales?

If it says "Philippines" , then why not? they may very well have a plant there, even if headquartered in USA.

As an example, here's a list of plants owned and operated by ST, Europe's largest semiconductor maker, with "official" headquarters in Switzerland:

Manufacturing facilities

Major sites include:
Grenoble, France

Rousset, France

Tours, France

Milan, Italy

Catania, Italy

Kirkop, Malta

Ang Mo Kio, Singapore

Tunis, Tunisia

also:

Assembly plants

Malta
Muar, Malaysia
Shenzhen, Guangdong province, China, near Hong Kong
Calamba City, in the province of Laguna, Philippines

Ready to sell semiconductors would have the assembly/packaging factory Country printed on the case (since that was the last significant operation), even if the actual chip inside was made elsewhere.

Many smaller semiconductor companies use third party test and packing companies, that you have never heard of. These are usually in SE Asian countries

Please no need to rev up the fake paranoia. Packaging and assembly in the Philippines is pretty standard the wafers are made in the LS fabs. This is all standard practice.
