2.05 MΩ resistor colour code
Five bands: Red · Black · Green · Yellow · Brown. The first three give the digits — a precision value needs all three — then the multiplier, then how far off the real part may be.
Nominal

2,050,000 ohms
Real range at ±1%
2.0295 MΩ – 2.0705 MΩ
A brown band allows this much drift.
Series
E96
A 1% precision value. Five bands, not four.
Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Red | 1st digit — 2 |
| 2 | Black | 2nd digit — 0 |
| 3 | Green | 3rd digit — 5 |
| 4 | Yellow | Multiplier — ×10k |
| 5 | Brown | Tolerance — ±1% |
How much it can take
Current and dissipation across the resistor, and the package you need. The suggested rating keeps a factor of two in hand, which is what anyone building a board actually does.
| Across it | Current | Dissipated | Package to pick |
|---|---|---|---|
| 3.3 V | 1.61 µA | 5.31 µW | 1/8 W |
| 5 V | 2.44 µA | 12.2 µW | 1/8 W |
| 12 V | 5.85 µA | 70.2 µW | 1/8 W |
| 24 V | 11.7 µA | 281 µW | 1/8 W |
What you can actually get
Standard on paper, absent from the shelf.
2.05 MΩ is a proper E96 value, but no part carrying it is currently held for assembly. The nearest value you will actually find is 2.05 MΩ.
What ten of them actually cost
The price everyone quotes is the reel price. If you want ten, you cannot buy the reel — and the real figure is usually several times higher per piece.

Per piece, ten costs 9.6× the reel price. That gap is why a handful of resistors never costs what the headline price suggests.

The same value, marked differently
Values that can overlap this one
At ±1% the tolerance bands of neighbouring values run into each other. A part sold as one of these could measure the same as a 2.05 MΩ — which is why measuring beats reading when it matters.
If you do not have one
Standard values that land within 1% of 2.05 MΩ when combined.
