2.2 µF Capacitor 0805 - Samsung CL21A225KAFNNNG

@@ -24,6 +24,10 @@ Its insulation-resistance spec is the strong one in this group: 10,000 MΩ or 50  The limits to respect: the X5R window closes at +85 °C, not 125, (p.2) and as a Class II ceramic its capacitance drops under DC bias, the product manual explicitly requires checking the bias characteristic at your working voltage. (p.14) 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 (`CL21A105KAF1INE.STEP`, published through SnapEDA as "Created with Samsung"). Samsung builds its MLCC models at the top of the thickness tolerance, so this one is 1.36 mm tall against the 1.25 +/- 0.10 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 0.476 mm).
