In the electronics industry, SMT resistors are one of the common electronic components. In order to meet different circuit requirements and improve production efficiency, manufacturers offer various types of SMT resistor packaging. This article will introduce you to the dimensions and power parameters of SMT resistor packaging
1、 Package size (in millimeters)
The following are several common sizes for SMT resistor packaging:
10x25 1216 (mm2)
16x32 1608 (mm2)
20x40 2512 (mm2)
25x52 3225 (mm2)
32x65 4768 (mm2)
50x100 5025 (mm2)
Note: The packaging size is in millimeters and represents the length of the resistor at both ends, where 1 mm=0.1 mm
2、 Power range
The power parameters of SMD resistors are usually expressed in ohms, and the following are some common SMD resistance values in the power range:
1/16W @ 1k Ω~± 6% (@ 1%)
1/32W @ 1k Ω~± 6% (@ 1%)
1/64W @ 1k Ω~± 6% (@ 1%)
1/128W @ 1k Ω~± 6% (@ 1%)
1/256W @ 1k Ω~± 6% (@ 1%)
(Omitting some power values)
These power ranges may vary depending on the manufacturer and brand. When selecting SMT resistors, please be sure to consult the relevant product manual for accurate power information
