How can I tell what a size/resistance a cooked friken tiny surface mount resistor used to be .. ( HP bluetooth GPS unit ... the bluetooth still works)
There are several others identical in size and appearance next to it .. could I take resistance measurements from that an replace it with a unit the same size .. what have I got to loose ??? it farked as is..
I know why the unit is fried ... an 14 year old with small phillips head screwdriver a 9v battery and some leads ... and a sore backside after his dad kicked it ...

Replace a surface mount resistor

Replace a surface mount resistor

there sized by colour coding of the rings around the body of the resistor. NFI what the code is, i learnt that years ago and never used it again.
-Scott- would know it though. Otherwise i reckon you could probably get it from the dick smith electronics site.
im no electronics guru either, but i dont think resistors fail that often??

.. does the gps side still work ? or just the bluetooth side?
Re: Replace a surface mount resistor
The resistors could be any resistance, and given that it is fried and you don't have the cct diagram for it, it would be very difficult what value to get for sure.

If it is worth repairing, take it back to the distributors and see if they will have a look at it. Otherwise ditch it, as the extra 9 volts in the cct at the wrong points is likely to have take out a bit more than just the resistor.

I don't think the SMD resistors are done that way as there isn't enough "acreage" on them to be visible.mickyd555 wrote:there sized by colour coding of the rings around the body of the resistor. NFI what the code is, i learnt that years ago and never used it again.

Usually they will have a three igit/letter code eg 10K, 4K7, 1M2. If you can see that on the body of the resistor with a magnifying glass if needed, you might be able to get it replaced.
Could you return the GPS/Bluetooth as a warranty repair? (If it doesn't look too tampered with)

all surface mount reisistors ive worked with just have very fine writing on themDAMKIA wrote:I don't think the SMD resistors are done that way as there isn't enough "acreage" on them to be visible.mickyd555 wrote:there sized by colour coding of the rings around the body of the resistor.

5k6 etc.
I am not having any fun with fine delicate equipment .. my digi cam (the one that can do macro anyway) has decided it is doing its best to make all my pics look like watercolors ... arghhhh ...
I believe we have a unit like this at work ,, I will see if it needs to come to the IT dept for a some reason
.. see what resistor it is .. and hopefully get a replacement ...

Damn shame if the one at work happened to blow up. Perhaps you could lend them your working onelove_mud wrote:I am not having any fun with fine delicate equipment .. my digi cam (the one that can do macro anyway) has decided it is doing its best to make all my pics look like watercolors ... arghhhh ...

Hi love_mud, surface mount resistors use alphanumeric code called the EIA Code, to indicate their resistance value.
If you have an Altronics or Dick Smiths catalogue, you will find the EIA code listed in the data section of either catalogue.
It is also common practice in constructing surface mount electronic devices, to design the circuit to use as many of the same values as the circuit will allow, this helps to speed up construction and reduce costs. So you may be lucky and the surrounding resistor just might be the same.
Cheers and best of luck.

if its the same as the little belkin module i have one here, if you can get a pcb shot i can match it up and ill be able to get a new resistor for ya and fit it too if your nearby, been doing SMD stuff for a few years, pm me if i can help.

ps im sure there will be 100 smd resistor javadecoders on the net if you google, but be carefull smd caps, resistors and rf chokes all look very similar it may have not even been a resistor.
cheers
