The most common resistors are 1/4W 5% carbon film. Unless otherwise specified, this is what is considered the ‘default’ resistor. 5% resistors are available in the following values:
2.2, 2.4, 2.7, 3.0, 3.3, 3.6, 3.9, 4.3, 4.7, 5.1, 5.6, 6.2, 6.8, 7.5, 8.2, 9.1 10, 11, 12, 13, 15, 16, 18, 20, 22, 24, 27, 30, 33, 36, 39, 43, 47, 51, 56, 62, 68, 75, 82, 91, 100, 110, 120, 130, 150, 160, 180, 200, 220, 240, 270, 300, 330, 360, 390, 430, 470, 510, 560, 620, 680, 750, 820, 910, 1.0K, 1.1K, 1.2K, 1.3K, 1.5K, 1.6K, 1.8K, 2.0K, 2.2K, 2.4K, 2.7K, 3.0K, 3.3K, 3.6K, 3.9K, 4.3K, 4.7K, 5.1K, 5.6K, 6.2K, 6.8K, 7.5K, 8.2K, 9.1K, 10K, 11K, 12K, 13K, 15K, 16K, 18K, 20K, 22K, 24K, 27K, 30K, 33K, 36K, 39K, 43K, 47K, 51K, 56K, 62K, 68K, 75K, 82K, 91K 100K, 110K, 120K, 130K, 150K, 160K, 180K, 200K, 220K, 240K, 270K, 300K, 330K, 360K, 390K, 430K, 470K, 510K, 560K, 620K, 680K, 750K, 820K, 910K 1.0M, 1.2M, 1.5M, 1.8M, 2.2M, 2.4M, 2.7M, 3.3M, 3.9M, 4.7M, 5.6M, 6.8M, 8.2M
Mouser’s brand is Xicon, and the part numbers are encoded as 30BJ250-1.0K where the bold part at the end is the resistance value.
Digikey’s brand is Yageo, and the part numbers are encoded as 1.0KQBK-ND where the bold part at the beginning is the resistance value
Mouser’s Xicon brand 1% metal film resistors are encoded as 271-10K-RC where the bold part in the middle is the resistance value (10K in this case)
Digikey’s Yageo brand 1% metal film resistors are encoded as 10.0KXBK-ND where the bold part in the beginning is the resistance value (10.0K in this case)
