Source: Vishay precision thick-film chip resistor data sheet.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Worked example.<\/strong> A 0603 rated 0.1 W sits in an enclosure that reaches 100 \u00b0C. Available power is 0.1 W \u00d7 0.65 = <strong>65 mW<\/strong>. The circuit puts 9 mA through a 1 k\u03a9 part: P = I\u00b2R = 0.009\u00b2 \u00d7 1,000 = <strong>81 mW<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The part fails \u2014 and this is the trap: at 70 \u00b0C the same 81 mW would have sat comfortably inside the 100 mW rating. The part passes on the bench and fails in the enclosure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why small packages are hit hardest.<\/strong> Power density rises as the body shrinks, and there is less pad copper to sink heat into. The pad and its copper are part of the thermal path, which is why the land pattern in the next section is also a thermal decision, not only a mechanical one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Mitigations,<\/strong> in the order worth trying: move up a package size, widen the pads and the copper connecting to them, add thermal vias where the layout allows, or split the dissipation across two parts in series or parallel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Land Patterns and Pad Geometry<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The pad dimensions decide whether the part solders reliably, and they are not the same as the component dimensions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The pad is deliberately larger than the termination. That extra copper gives solder somewhere to wet, and it gives the part self-alignment: surface tension in the molten solder pulls a slightly misplaced chip into position during reflow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Three dimensions govern the result. <strong>Pad width<\/strong> sets joint strength. <strong>Pad length<\/strong> \u2014 the extension beyond the termination \u2014 sets the fillet and the self-alignment force. <strong>The gap between the two pads<\/strong> sets bridging risk and decides how much solder sits between the terminations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IPC-7351 defines three density levels. <strong>Level A<\/strong> gives the most land protrusion and the widest process window, and suits low-density boards and wave soldering. <strong>Level B<\/strong> is the nominal default and is what most production boards use. <strong>Level C<\/strong> gives the least protrusion for high-density designs, and IPC-7351 calls for user qualification before adopting it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vishay&#8217;s land pattern document states that its figures reflect IPC-7351 and IEC 61188-6-2, and it publishes a set for each (<a href=\"https:\/\/www.vishay.com\/doc?28950\">Vishay, recommended solder pad dimensions for surface-mount resistors and fuses, document 28950<\/a>, retrieved 2026-10-21). In both, <strong>C is the gap between the two pads, Y is the pad length along the component axis and X is the pad width across it<\/strong>, so the overall footprint is Z = C + 2Y:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">\u30d1\u30c3\u30b1\u30fc\u30b8<\/th><th class=\"has-text-align-left\" data-align=\"left\">IPC-7351, reflow (C, Y, X, Z)<\/th><th class=\"has-text-align-left\" data-align=\"left\">IEC 61188-6-2, reflow (C, Y, X, Z)<\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-left\" data-align=\"left\">0201<\/td><td class=\"has-text-align-left\" data-align=\"left\">0.27, 0.43, 0.42, 1.13<\/td><td class=\"has-text-align-left\" data-align=\"left\">0.30, 0.24, 0.32, 0.78<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">0402<\/td><td class=\"has-text-align-left\" data-align=\"left\">0.40, 0.55, 0.60, 1.50<\/td><td class=\"has-text-align-left\" data-align=\"left\">0.55, 0.35, 0.55, 1.25<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">0603<\/td><td class=\"has-text-align-left\" data-align=\"left\">0.70, 0.90, 1.00, 2.50<\/td><td class=\"has-text-align-left\" data-align=\"left\">0.90, 0.55, 0.90, 2.00<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">0805<\/td><td class=\"has-text-align-left\" data-align=\"left\">1.00, 0.90, 1.45, 2.80<\/td><td class=\"has-text-align-left\" data-align=\"left\">1.10, 0.65, 1.30, 2.40<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">1206<\/td><td class=\"has-text-align-left\" data-align=\"left\">1.75, 1.15, 1.80, 4.05<\/td><td class=\"has-text-align-left\" data-align=\"left\">2.10, 0.80, 1.65, 3.70<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">1210<\/td><td class=\"has-text-align-left\" data-align=\"left\">1.75, 1.15, 2.65, 4.05<\/td><td class=\"has-text-align-left\" data-align=\"left\">2.10, 0.80, 2.50, 3.70<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Read the 0603 row as two pads 1.00 mm wide and 0.90 mm long, separated by a 0.70 mm gap, giving a 2.50 mm overall footprint.

Pads are defined as solder-mask-defined or non-solder-mask-defined, and the stencil aperture is usually reduced from the pad to control paste volume. And unequal copper on the two pads of a small chip means unequal heating, which is the primary mechanism behind tombstoning \u2014 picked up again in the assembly section.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Voltage Rating and Other Limits<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A chip resistor carries two independent limits \u2014 a power limit and a voltage limit \u2014 and on small packages the voltage limit usually binds first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Power rating is a thermal property. Voltage rating is a dielectric property, set by the body length and the spacing between terminations. They are physically unrelated, and both must be satisfied.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The crossover is where the binding constraint flips. A resistor reaches its rated voltage at V = \u221a(P \u00d7 R), so the critical resistance where voltage takes over from power is R = V\u00b2 \u00f7 P. For a 0402 rated 50 V and 1\/16 W, that is 50\u00b2 \u00f7 0.0625 = <strong>40 k\u03a9<\/strong>. Above 40 k\u03a9 the part is voltage-limited and can break down while dissipating a small fraction of its rated watts. For a 0603 rated 75 V and 0.1 W the crossover is about 56 k\u03a9, and for a 1206 rated 200 V and 1\/4 W it is about 160 k\u03a9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical maximum working voltages for general-purpose thick-film series run roughly 50 V for 0402, 50\u201375 V for 0603 and 100\u2013150 V for 0805.

SMD resistor is a fixed-value resistor in a leadless rectangular package that solders to pads on the surface of a printed circuit board rather than passing through holes.

Most guides to these parts stop at two questions: what size is it, and what does the code mean. Both matter, and both are answered below.
