①② ③ ④ ⑤
①Code designation Samsung Thick - Film Chip Resistor
②Dimension 322
(mm code) L : 3.2 ± 0.2 mm W : ± 0.2 mm
T : ± 0.1 mm
③Resistancs tolerance ±5 %
④Nominal resistance value ※3digits
Left 2 digits : Resistance value,Right 1 digits : Exponential number of 10.
ex) 101 : 10×101 = 10×10 = 100Ω
※4digits
Left 3 digits : Resistance value,Right 1 digits : Exponential number of 10.
ex) 4222 : 422×102 = 422×100 = 42.2㏀
Read alphabet "R" as decimal point "000" : Jumper(0Ω)
ex) 3R7 : 3.7 = 3.7Ω / 88R7 : 88.7 = 88.7Ω
