The naming method of domestic chip
1, 5% precision naming: RS-05K102JT
2, 1% precision naming: RS-05K1002FT
R - indicates resistance
S - indicates power: 0402 is 1/16W, 0603 is 1/10W, 0805 is 1/8W, 1206 is 1/4W, 1210 is 1/3W, 1812 is 1/2W, 2010 is 3/4W, 2512 is 1W .
05 - indicates size (inches): 02 indicates 0402, 03 indicates 0603, 05 indicates 0805, 06 indicates 1206, 1210 indicates 1210, 1812 indicates 1812, 10 indicates 1210, and 12 indicates 2512.
K - indicates a temperature coefficient of 100 PPM.
102-5% precision resistance representation: the first two digits represent a significant number, the third digit indicates how many zeros, the basic unit is Ω, 102 = 10 × 102 Ω = 1000 Ω = 1 KΩ. 1002 is a 1% resistance representation: the first three digits represent significant digits, the fourth digit indicates how many zeros, the basic unit is Ω, and 1002 = 100,000 Ω = 10 kΩ.
J - indicates an accuracy of 5% and F- indicates an accuracy of 1%.
T - indicates the tape package.
