4k7 =: 4700 (4.7 k)
Formula
- d(AWG) = 0.127 mm · 92^((36−n)/39)
- P(mW) = 10^(dBm/10)
- 1 mil = 0.0254 mm
- 1 oz/ft² Cu ≈ 34.8 µm
FAQ
- What does 4k7 mean?
- It is 4.7 kΩ. The prefix letter replaces the decimal point so it can't be lost when printed small.
- Is 1 oz copper always 35 µm?
- Nominally about 34.8 µm, but plating and etching change the final thickness on a real board.
