The SMD resistor code F11 stands for 27 MΩ / 2%, in words: twenty-seven Megaohms with two percent tolerance.

SMD resistors with a 2%, 5% or 10% tolerance can be marked using A11 format (letter followed by two digits). The letter indicates the multiplier. The digits (numbers) range from 01 to 60. They have a double function: they indicate the value and the tolerance at the same time. The numeric combinations from 01 to 24 indicate 24 values of the E24 table and a 2% tolerance. The combinations from 25 to 48 indicate 24 values of the E24 table again, but with a 5% tolerance. Finally, the combinations from 49 to 60 indicate 12 values of the E12 table with a 10% tolerance. The usage of a letter prevents the confusion with 3-digit marking system. The letter is at the beginning to prevent confusion with EIA-96 marking of +/- 1% resistors. Code "D03", for example, indicates a 120 kiloohm resistor. The number 03 indicates the 3rd value of the E24 table (120) and D indicates multiplication by 1000. The value is then 120 x 1000 = 120 000 ohms or 120 kiloohms. The number is in 01 - 24 range, so the tolerance is 2%. Code "D27" means the same value (120 kiloohms) but with a 5% tolerance, because range 25 - 48 means 5%. Number 27 is 3rd in this range, indicating the 3rd value of E24 table - value 120. Letter D indicates multiplication by 1000, just like in the previous example. Code "D51" is a 150 kiloohm resistor. The tolerance is 10%, because the number is in the 49 to 60 range. Number 51 is 3rd in this range, indicating the 3rd value of E12 - value 150. Letter D multiplies by 1000 as always. Note that 2% and 5% resistors have 24 possible values per decade, while 10% resistors only have 12 possible values per decade.



This is a simple online calculator for color band resistor marking, inductor color band marking, ceramic or tantalum capacitor 3 digit marking and SMD resistor 3-digit, 4-digit, 10%, 5%, 2% and EIA-96 (E96) 1% tolerance code marking.
