Hi guys,

I have an Astro Flight 109 Charger, and I had a problem with it.

I need to know what component is in this photo below or the eletric schema or photo like below.



If somebody knows what component is that, I will appreciate the information.

Best Regards

Not sure but most likely a surface mount capacitor.

I guess a varistor, because it's green like a smd varistor. But I'm not sure.

Thanks

I'd really like to help but there no markings on his component what so ever.

Maybe you can help me, I had one of the 7 power mosfet like devices blow out - I can not even read the markings on it anymore. That would be on the other side of the board (right on your photo), second one from the outside. Can you please provide me with whatever is written on this part?

Much appreciated!

Hi,

The power mosfet is IRF 4905.

Can you send me a photo from the board? And do you known how many ohms have on the component that blow out?

Thank you!

I must be getting old - a picture of this board revealed some markings.

By the way, this is what my HEXFET looks like.

Thank you for the Photos!

I hope that you recover your charger!
