CL21B105KBFNNNE - Multilayer Ceramic Capacitor

@@ -25,6 +25,10 @@ The reliability table gives the rest of the design numbers: dissipation factor 0  Two Class II realities still apply. Capacitance moves with applied DC bias, so check the bias curve at your working voltage instead of trusting the label. (p.14) And mechanical strain is a spec, not a footnote: the bending test allows up to ±10% capacitance change at 1 mm of board flex. (p.2) It ships 2,000 to a 7-inch reel on 4 mm-pitch embossed tape. (p.4) +## 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).
