Commented Oct 12, They ensure optimum use of board space, compact size, and low noise. For some reason Kemet recommend a . Adding an additional fabrication tolerance to the pad size calculation is a “Double (duplicate) Tolerance” and is unnecessary. 50 nH is obtained when the smaller 0402 size capacitor is mounted using the via-on-side scheme with wide connecting traces to the larger 20 mil via drill diameter. 6 1. When designing with surface mount components, the right solder pad size and land pattern should be used. In the case of 0402 components, these pad designs will actually differ slightly in physical size as detailed below (Figure 7-9). The 0402 package is nearly the smallest chip resistor package; only the 0201 chip resistor package is smaller. 8mm: 4000: 8mm Pitch 4mm Large Size Chip RoHS: Size (inch) Size (metric) Qty Per Tray: Tray Packaging: Tray Order Number: PDF Dwg: 3035 0. ---<(kaimartin)>---Continue reading on narkive: Search results for 'size of 0402 footprint' (Questions and Answers) 3 Lenpad = Length of the capacitor pads plus trace length from pad to the via (mils) Lencap = Length of the capacitor body (mils) the optimum mounting inductance of 0. ± 5% Temperature Coefficient of Resistance Resistance Value Code Type 15 27 33 39 ERAV, ERAS ERAW, ERAV, ERAS ERAW, ERAV, ERAS ERAV, ERAS 1500 2700 3300 3900 ( 10–6/°C) For example, is it possible to compare the footprints of 0603 and 0402 components to determine if I can use an Through-hole footprints: pad size from technical drawings. 79 1.

So 0402 for small size solution, still hand-solderable, or 0603 for not as good but still acceptable size solution, easily hand-solderable. 54 mm / 0. The board also has two QFPS, so my stencil design at those locations uses trapezoidal apertures reduced down to 80% of the pad size. 5mm to 0. 3mm) and 0603 (1. For fine pitch components, apertures are often slightly reduced to compensate for paste spread. If you are planning to have pads for a large tantalum cap, then having small 0402 ceramic capacitors doesn't give an advantage, because the large pads for the tantalum cap are there anyways. 0 x 0. 8 mm 0805 0. 10 P0.
