4.7 µF Capacitor 0805 - Samsung CL21A475KAQNNNG

@@ -24,6 +24,10 @@ Dissipation factor is 0.1 max at 1 kHz / 1.0 Vrms, insulation resistance is 10,0  The other Class II tax is DC bias: effective capacitance falls as working voltage rises, and the product manual requires checking the bias curve rather than assuming 4.7 µF at your rail. (p.14) The X5R window also closes at +85 °C. (p.2) Reflow is rated 260±5 °C peak for 30 s, and it ships on embossed tape on a 7-inch reel. (p.2, p.1) +## 3D model provenance++The STEP is Samsung Electro-Mechanics' own model (`CL21A105KAQ1INE.STEP`, published through SnapEDA as "Created with Samsung"). Samsung builds its MLCC models at the top of the thickness tolerance, so this one is 1.41 mm tall against the 1.25 +/- 0.15 mm thickness Samsung lists for this part. Samsung exports it lying on its side (Y up); it is stood upright (Z up, seated on the board) without changing its shape or colours. Samsung's file is kept byte for byte in `provenance/`, beside the previous model.+ ## Footprint  Redrawn from the datasheet land pattern (the previous pads were off by up to 0.326 mm).
