Have you tried the local markets? Title: Re: help me in finding electronic parts mosfet... Post by: vineet on January 05, 2012, 01:23:58 PM yes i had , went through all the shops mostly , nobody have, some guys on ebay selling at 40 rs per peice , and some of them from some chinese website selling them at 10 rs but dont know if they are turst worthy.. like from alibaba.com.
what should be the price according to you Title: Re: help me in finding electronic parts mosfet... Post by: reas on January 05, 2012, 01:49:29 PM I have some IRLR8743 lying around not the 7843. ordered them to make an BLDC ESC myself. similar specs though. well, yeah they are costly if you live in India ! pm me if you want some. I have the D2PAK though.
Title: Re: help me in finding electronic parts mosfet... Post by: KALYANPRODHAN on January 05, 2012, 10:43:10 PM If you want cheap, go to electronics waste and search faulty motherboards. I have seen that MoBo technicians are searching MoBo lots (Garbage) for their items.
However, I will search not only of your item but need to explore SMD Market in Kolkata. May be delay to you. Title: Re: help me in finding electronic parts mosfet... Post by: reas on January 05, 2012, 11:09:45 PM if the original ESC had through hole mosfets i'm afraid these may not work.. these are SMD.
attatched some pics.. could you also attatch some pics of your ESC.. lets have a look :) Title: Re: help me in finding electronic parts mosfet... Post by: vineet on January 05, 2012, 11:59:20 PM here i go
Title: Re: help me in finding electronic parts mosfet... Post by: vineet on January 06, 2012, 12:00:10 AM some more
Title: Re: help me in finding electronic parts mosfet... Post by: reas on January 06, 2012, 11:41:33 AM yeah, those are DPAK, same as I have.. I see there is only one damaged mosfet..
yes, you sure can try as kalyanprodhan says.. rummaging helps a lot.. but i'm not sure if you'll get a 120A transistor.. Title: Re: help me in finding electronic parts mosfet...
