Had csi 825 hot air station go bad.
Getting bad readings on this resistor
Could do with some help identiying the rating

Re: Some help identifiying a resistor
So its
Brown Black Gold GOld
1ohm resistor
Its massive through
3cm wide
Its been used as a fuse resistor
Any recommendations on where to source repalcement -
Re: Some help identifiying a resistor
1ohm 5%
wattage will depend on size.
it's a flameproof type btw.Comment

http://www.maplin.co.uk/p/wirewound-...m-resistor-h1r
will that replace it ?
Its 24mm Length
8mm widthComment

Re: Some help identifiying a resistor
If it's used as a fuse resistor you may have a short somewhere else too.
Source from wherever you like. eBay, Farnell, Digikey, etc.
That one you linked to should be fine, but it's not going to fail like a fuse in the same way as the old one did on overload. You may wish to add a real fuse in series as well.Last edited by Agent24; 01-01-2017, 08:56 PM."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Some help identifiying a resistor
The element blew out
And took the fuse resistor with it..
A glass fuse ?
thanks for the info guysComment

Re: Some help identifiying a resistor
dont use wire-wound - they are inductive.
use metal film typeComment

Re: Some help identifiying a resistor
Glass is OK, ceramic is better.
Would the inductance of a wire-wound resistor really matter here, given that the heating element is probably coiled and has its own parasitic inductance anyway?"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

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 -
Hi, while trying to replace a broken screen connector on the motherboard, I knocked off a resistor next to the connector, and the resistor vanished. I have tried to find out the value of the resistor by looking at the schematics, but I cannot find the value. The ID of the resistor, or what you should call it, is R6400.
I don't know if the resistor is necessary for the phone to function, and the connector is still not soldered on to motherboard. I have contacted Xiaomi and asked them if they know the value, but they want a proof of purchase, which I don't have.
Is...
