Note:
Character code representation rules:
0402 and below specifications, represented by no character code
0603 Specification: ± 1% (F), ± 5% (J) are all represented by "three codes"
For example: resistance value of 100m Ω=0.10 Ω=R100=R10 represents
Resistance value of 10m Ω=0.010 Ω=R010=010 represents
Specifications 0805 and above: ± 1% (F), ± 5% (J) are represented by "four codes"
For example: resistance value of 100m Ω=0.10 Ω=R100=R100 represents
Resistance value 10m Ω=0.010 Ω=R010=R010 represents
