Hi I have two smd resistors of different value one R100 and the other R220 that I want to replace what alternative value can I have ? they are from two different HD motherboard that I am trying to repai

do you have any more clues ? -
Re: Smd resistor alternativ
Hi petehall347. have you read what was the solution for Skodan that you helped to solve ? Read it because it was a very funny problem. what more clues do you want?Comment

Re: Smd resistor alternativ
post me a link to that thread .
with your resistors it all depends on the circuit etc .Comment

Re: Smd resistor alternativ
https://www.badcaps.net/forum/showth...light=bohaboha .it's to a hard drive that both don't work if you want a picture of them? but in general which is the closest replacement that you can use because I don't have at homeComment

Re: Smd resistor alternativ
If the smd resistors are labeled like this : "R100" , "R220" , then they are 0.1 ohms and 0.22 ohms . Their size is important also , but usually in Hard drives , they're 2 Watts .Comment

Re: Smd resistor alternativ
thank you very much I am trying to find similar on my HD cards parts but no on 15 almost similar cards therefore now I am looking for Equivalent if you can advise meComment

Re: Smd resistor alternativ
Wait, does the resistor say Rxxx on it, or does the board say Rxxx on it? If the labels are on the resistors then they indicate size like jiroy mentioned, but if they're on the board then they're just an internal reference number for the board designer and factory to use and don't tell us much without a boardview or schematic.
The best way to get a value is to remove the parts and measure them as small SMD resistors are often not labeled. Then a measurement of length and width (usu. in thousandths of an inch, easiest to measure mm and convert, or use calipers) will tell you what package you need to order.

Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.
I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors... -
The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y -
I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
Since then, This AC/DC adaptor have been out of order.
But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
And Is there any possibility that it will suddenly explode as well as to be out...
