MOS-FET`s wire linked ?

[B.I.G]

can i wire link some mos-fet`s ? i`ve heard that mos-fet`s can oscilate if they are wire linked !!

the amp is a Holton symetrical 400W with IRFP240/9240 .

how long should the wires be ?

Up to 10 mm and you haven't problems. 😎

Any reasons why you have to wire linked them in the first place? They are all on board, nice and easy!

10mm or 10 cm ?? even the board has links well over 10mm !! about 40mm of pcb link till the last fet !

You must make all " wire " shortest as possible - look at photo 😎 .

Why do you want to do this ?

i want to do this because i have lack of space and can`t mount the transistors on the board

Ive done this with my blue amp.. * blue is what i call them * ill post a picture for you if you want. ?

ok post it please ! 🙂

i`ve conected one channel with the Gate and Source twisted ! the lenght is about 10cm or 4inch ! if we look at the AV800 you can se that the total lenght ftom gate to driver is a lot more than 10cm

Hi,
it is recommended that the gate resistor is mounted directly onto the gate leg with absolute minimum length of leg/wire between FET case & resistor body.
After that the total link lengths are less important, but make them as short as practical
