brother I am in Jordan, components here in Jordan are much expensive due to high exchange rate of Jordanian Dinar. moreover the shipping charges are too high I will check tomorrow and will reply. because to send or receive any electronics parts and items needs a special customs approval. I will check. if it will easy and economic I will send if the shipping charges are much high then I will not recommend to purchase components from this country

I'm cheap. I used my hand sterilizer alcohol/gel to remove the flux, then washed off the leftovers with water. Worked great. LOL I had to replace 7 bad electrolytic capacitors in my Lenovo ThinkCentre m58p computer PSU. One bad cap in particular was causing the computer to be stuck in boot looping status. The rest of the bad caps were bulging at the top and thus needed to be replaced. So that was about $9.53 to fix the PSU.

@HaseebElectronics2 жыл бұрын
in this situation we need to download the datasheet, application note, sample circuit or typical application circuit for that main component or IC. so we can get a very closer value for that burnt out component. otherwise it needs a detailed and too much time consuming reverse engineering to recalculate the all components to find the burnt out component value

1 second ago 1 it is impossible to include a low-frequency diode 1N4007 in a circuit with frequencies above 1 kHz! only ultrafast FR107 (HER107) diodes need to be installed there 2 it is impossible to connect the power supply to the mains without making sure that the parts of the COLD side are working properly and that the feedback is working correctly, only after checking the serviceability of the feedback circuits can you try to supply power from the mains - otherwise there is a huge probability of completely burning such a unit. OVERVOLTAGE protection power supply ON KEY DIODES AND CAPACITORS Tip in case of any problems with the hot part, replace the optocoupler with a PC817 (yt is even worth checking the old one - ALWAYS CHANGE) the same applies to the PWM power supply capacitor

@HaseebElectronics2 жыл бұрын
the series lamp is 60 watt or 100 watt. and the kettle resistance is 1500-2000 watt. so lamp will glow full, because the lamp have more resistance than the kettle resistance. if we see the voltage drop across the two resistors in series, then the kettle resistance is much low than the lamp resistance, in result the kettle resistance will not get more voltage to produce enough wattage
