markdown6.8 Ω Resistor 0603 - Stackpole RMCF0603FT6R80
SEI Stackpole RMCF0603FT6R80: 0603 Thick Film Resistor, 6.8 Ω ±1%, 0.1 W. An Adom Basic Part: Adom keeps it on reels for its pick-and-place line, so boards built with it draw on Adom stock.

Notes for designers
RMCF0603FT6R80 is a 6.8 Ω ±1 % thick film chip resistor from Stackpole’s RMCF series in the 0603 size, the general-purpose, standard-power branch of the family (RMCP is the high-power one). (p.1) Values this low are written with ‘R’ as the decimal holder (6R80 → 6.8 Ω) (p.15), and the 0603 carries a 3-character marking, underlined on recent date codes to flag the 1 % tolerance. (p.12)
The 0603 size is rated 0.1 W at 70 °C, derating to zero at +155 °C, and the part operates from −55 to +155 °C. (p.1, p.4) Two numbers are easy to misread at this end of the ohmic range. The 75 V column figure is a ceiling, not a promise: rated continuous working voltage is the lesser of √(P×R) and 75 V, and at single-digit ohms the √(P×R) term is the one doing the limiting. (p.1) And TCR here is ±200 ppm/°C, the 1-9.76 Ω band is specified looser than the ±100 ppm/°C the 10 Ω-1 MΩ band gets. (p.1)
Budget drift the same way: the load-life limit is ±(1 % + 0.05 Ω) after 1000 h at 70 °C (p.3), at a value this low the fixed 0.05 Ω adder is on the same order as the percentage term itself, so the real-world tolerance stack is wider than ±1 % alone suggests. Ships as 5,000 pieces of paper tape on a 7-inch reel. (p.15)

| Pad width | 0.9 | 0.95 | 1 | 0.9 |
| Gap between pads | 0.8 | 0.85 | 0.7 | 0.8 |
| Centre to centre | 1.45 | 1.65 | 1.6 | 1.45 |

| Corner radius | not specified | 0.2 (ratio 0.25) | 0.225 (ratio 0.25) | square (as drawn) |
| Corners: square, as the datasheet draws them. The datasheet does not call for rounded corners, so the footprint does not add any. |
Chip outline
The part's 3D outline in the standard pose (pad 1 toward the viewer), drawn from the STEP by Adom's OpenCascade service; the part number sits where the laser-etched mark is on the 3D model and reads the same way.
Symbol options
The default symbol, RMCF0603FT6R80.kicad_sym (the one in the Symbol & Footprint panel), is the plain standard symbol. RMCF0603FT6R80-outline.kicad_sym is the same symbol with the part's 3D chip outline drawn beside it, its part number placed and reading as on the 3D model.
