I'm familiar with the common 4 colored bar resistor but have run across some that are all dark red with either one or both ends painted rreen or white or blue and with a value printed on them like 1/2 1M or 16K. I have both types in my Nordmende...but can find no information on the web about those with the printing and no standard colored bars. Can anyone tell me about these resistors and why they don't follow the standard coloring convention of 4 bars? Thanks

Examples of schematic notation of capacitors and resistors seen on Philips and other European schematics.

Resistors:
1Ω =1 Ohm
1kΩ =1 Kiloohm
1MΩ =1 Megaohm
1GΩ =1 Gigaohm

1 Ohm = 10-3kΩ = 10-6MΩ; = 10-9GΩ
Examples as seen on Philips and other European schematics:
100 = 100Ω
4k7 = 4.7k = 4.7kΩ = 4700Ω
8M2 = 8.2M = 8.2MΩ = 8 200 000Ω

Edit: there are at least a dozen Nordmende models branded Tannhauser.
Do you know which one you have?

Printing the characters may be used to signify a more precise (precision) value used, rather than color codes.
At least in the USA.
