Where I can find mica insulator MT-200?

[viktor1986]

Hi

I need insulator for Sanken 2SC3264 and 2SA1295 transistors.Does anybody know where i can buy MT-200 insulators?I searched on the web but with no succes.

Why not buy a mica sheet and cut it to size, I make to-220 insulators out of to-3's all the time,.

Anyway, most mt-200 packages I
have seen are electrically isolated and need no insulator for
less thermal resistance.

you told lies about searching for mt200

Damn, the holiday season isn't over yet and Mr T looks like he needs another break again.

Hi Victor,

Mica MT200 insulators can be found, but they're usually pretty expensive.
I live about 5 miles from the BMM audio parts shop(if you can call it a shop), it used to sell MT200 insulators at a rate of around $3 each up to a couple of years ago.
The owner Jean Benoit told me he stopped offering them because the demand was too low to make it worthwhile:

There's an online electronics parts store in Canada that has Mica MT200 insulators at really affordable rates.
They even used to add a number of Micas for free if you ordered some MT200 devices from them.
The downside is that you'd have to buy a substantial number of parts to make the steep shipping costs worth it, they only ship internationally with expensive fancy pants services.

The thread you emailed me about was a scam.
I offered to buy 500 of the MT200 Micas for several interested members overhere, but the guy in the Philippines wanted me to send him cash US$ currency.
The guy said he did not receive the money and asked me to send him dolares a second time. Yeah, Right !

If you do a google dive you'll find online vendors that offer Mica sheets, ranging from 4x4 inches to really giant sizes.
Those sheets are even very affordable, though not the highest quality mica.
There's quite a variety of mica grades, depending where it is coming from.
I've found Mica sheets easy to cut to size with a paper cutter board, holes in mica are also easy to punch.
Even easier if you DIY a punching mold from pieces of wood, aluminum or steel, the one i made punches holes in a stack of several micas in one go.

Other alternative is to look for JAP device mica insulators, those are large enough to rework and serve as MT200 insulators.
I've been building power amps with MT200 power devices for around 20 years now, finding Mica insulators for that package has always been a PITA.

Relax Max.

Nah, I'm sure it wasn't intentional, Andrew.

I (briefly) searched too but couldn't find an answer. These things might still exist but as mentioned, cutting them yourself will probably be the easiest way.
I fail to see how it could be made out of a TO3 insulator, though.

AndrewT,before I have made this topic I searched in another topics but with no succes.I saw that some pepole made MT-200 insolutor from 2 TO247 insulator but nobody hade gave web page where can be found!
