Marking Explanation

Resistors with 5 % tolerance may have a

3-digit or 4-digit resistance code.

Complete information about resistance

value and tolerance is found on the label

of the reel of chip resistors.

• 5 %: 3 digits, ﬁ rst two digits are

signiﬁ cant, third digit is number of

zeros to follow. Letter R is decimal point

for values from 1 to 9.9 ohms.

• 5 %: 4 digits, ﬁ rst three digits are

signiﬁ cant, fourth digit is number of

zeros to follow. Letter R is decimal point

for values from 1 to 99.9 ohms.

• 1 %: 4 digits, ﬁ rst three digits are

signiﬁ cant, fourth digit is number of

zeros to follow. Letter R is decimal for

values from 1 to 99.9 ohms.

Resistance Tolerance

F = ±1 % .............. Use with “X” TCR code only for values from 10 ohms through 1 megohm;

Use with “W” TCR code only for values from 1 megohm through 10 megohms

J = ±5 % .................Use with “W” TCR code for values from 10 ohms through 10 megohms;

Use with “Z” TCR code for values above 10 megohms through 20 megohms;

Use with “/” TCR code for zero ohm (jumper) and values from 1 ohm through 9.1 ohms.

TCR (ppm/°C)

X = ±100

W = ±200

Z = ±400

/ = Used with “J” Resistance Tolerance code for zero ohm (jumper) and values from 1 ohm through 9.1 ohms.

Resistance Value

For 1 % Tolerance:

<100 ohms...............“R” represents decimal point (example: 24R3 = 24.3 ohms)

≥100 ohms ...............First three digits are signiﬁ cant, fourth digit represents number of zeros to follow (example: 8252 = 82.5k W)

For 5 % Tolerance:

<10 ohms .............. “R” represents decimal point (example: 4R7 = 4.7 ohms)

≥10 ohms ............... First two digits are signiﬁ cant, third digit represents number of zeros to follow (example: 474 = 470k ohms; 000 = Jumper)
