Help with power resistor markings & value?

Aug 21, 2004 9 Replies

Rectangular ceramic power resistor in a Braun handheld blender (120 vac) is open.



Markings on resistor are: 206-8 R R47 10% *



(That's 10 percent followed by a dot, in case the symbol doesn't show up right on your computer...)



I did a Google on resistor markings and values, but got just traditional color codes, etc. The markings on this resistor are Euro designations, I presume.



What's the value of this resistor?



URL for future ref would be appreciated.



Thanks,

R47 is almost certainly 47 ohms. Don't know how many watts, but match the physical size of it and you'll come close.

Ah! Of course! The R for the decimal point. Thanks.

The "R" is used sometimes as a decimal point (4R7 = 4.7 ohms) so R47 could be 0.47 ohms. Buy both, try first the one of 47 ohms.

Thank you, Peter, and all others. I'm on my way to buy a 0.47-ohm, 5W replacement.

Thanks again,

Most certainly 0.47 ohms.

47000000 -> 47M 47000 -> 47k 47 -> 47R 4.7 -> 4R7 0.47 -> R47

47R certainly would be 47 Ohms. In the Euro style the R indicates the position of the decimal point, so R47 would more likely be 0.47 Ohms, in my humble opinion... dr

You are correct, we use 0R47 on our own schematics to reinforce the point, but R47 will be 0.47 ohms.

If that is the square ceramic cased types, they are a little bulky, but are slightly higher rated in W than equivalent wirewounds. The standard Vitreous enamelled 3W and 6W types are a close replacement as long as you don't need the slightly higher dissipation. The also do a solderable spike for them to allow vertical mounting with support, which can be useful to keep the heat off the PCB.
