They should do their own test. This is not a problem which is present in my item only. This is a general problem present in all ics in the same batch in their collection. So they shouldn't ask a customer make a video, instead their technical team should do the test.
Very nice information Great work for you Sir ji Sadar Namste 🙏🙏 सुप्रभात बहुत अच्छी जानकारी दी आप ने जारी रखें भारत सरकार को ईस विषय पर ध्यान देना चाहिए B E L,H C, को इन आई सी का उत्पादन करना चाहिए क्योंकि चीनी elektronik पार्ट्स पे ही निर्भर है भारत इलेक्ट्रोनिक लिमिटेड, कंपनी ब्रांड के ट्रांसिस्टर आई सी की क्वालिटी बहुत अच्छी होती थी लेकिन शायद बनाना कम कर दिया बहुत बहुत धन्यवाद
Ya scam IC ke sat he nhi mosfet transistor sat bhi hota hai market me jo IRFZ44N mosfet milta hai wo sab almost fake hi hote hai audio transistor audio IC bhi fake milta hai mara sat bhi aisa hua hai mai jab koi circuit banata hu to wo achaa kam nehi karta hi kyunki us mai fake component laga tha zab mai original component lagatha hoo thb wo achha se kam karta hai. 😢 big fan of your i have learned lots of things from you thank you for your knowledge
your test setup is correct; but you should do one reference test in which the IC is removed and the input is connected to the output via a 1k resistor. that will tell that your setup is good.
I also faced fake amplifier Ic problem in childhood but now I only purchase from branded trusted wholesale shop and give priority to ST and Texas Instrument IC first. Branded one also cost me around ₹15 to ₹20 in shop, why purchase online?
Sir, I need a suggestion from you. In use Xl6009 boost module, input voltage 5/12volt approx 15-20amp current and 3055 transistor. Can I get output voltage approx 24-30 volt and current approx 10 amp. Is it possible.plz suggest me.🙏🙏🙏❤️❤️💚💙
No, Not possible for step up purpose, you have to use some kind of coil to increase voltage. That might work for step down purpose, but why should you do that? We use switching converters (like XL6009) to get another level of voltage without wasting power. But if you use such a transistor to convert voltage level it will heat very much and loose power. Then no point of using switching converter there, u can get base driving voltage from a pot, or a zener diode etc.....

they asked you to make video and send them, you made video and uploaded to public! Good

Kaha se milta hai bhai original components
Thank you for making this Informative Video. 👍👌. China copy IC 😆😑
দাদা অনেক দিন পর ভিডিও এলো ❤❤
Love from Purba Bardhaman 😊😊
Sir Doso kaise istemal karte hain istemal ek ful details video banai hai na🙏🏻
Original ic me itna margin nhi hota islea copy sale krte hai. Tda 2030 copy 20rs ka aata hao original 50~60rs

Bro, give us some trusted websites
Good and simple explanation in Hindi.
Fak ic is a big problem for makanic
where do you buy parts?
Tlo72 ko use kr sakte he aha pr ?
Usme output oscillate krta hai. Compensation problem
Very good job
Good explanation👌✌️👍👏👏👏🔥
i am a big fan of robu, after your video i have to think about it. what was their response after your video??
Only way is buy from mauser or digikey or element14
We have tested and even in India battery like exide 7Ah ups version has many fakes.
So,for my application i am using discrete design substituting IC in my perticular application.
Can you suggest a design to get higher slew in discrete
Excellent job.
Good job 👍

Thanks bro
Sir fakeic to har website par milta hai.. Original bolkar fake ic bhej dete hai.. Aur return aur refund ka koi guaranty nahi dete... 😡😡😡
Can you probe the supply At ic pin
The supply is from battery, also there is decoupling cap. So power is clean

boycott this website... mai to ab nhi lunga ye website se... isko to dekh krle sell krna chahiye
Baki site isse vi gya gujra hai
Ehi ek site h quality components deta h
Konsa site name batha yen
I thought I only got fake ic in the local market and I thought I would not get fake from online but ...
I agree with that 😑🤦
