Resistance Tolerance
F = ±1 % ..............Used with “X” TCR code only for values from 10 ohms through 1 megohm; and
Used with “W” TCR code only for values above 1 megohm. through 10 megohms.
J = ±5 % ............... Used with “W” TCR code for values from 10 ohms through 10 megohms;
Used with “Z” TCR code for values above 10 megohms through 20 megohms;
Used with “/” TCR code for zero ohm (jumper); and for values from 1 ohm through 9.1 ohms.
TCR (ppm/°C)
X = ±100
W = ±200
Z = ±400
/ = -200 to +500
Resistance Value
For 1 % Tolerance:
<100 ohms ...........“R” designates decimal point (example: 24R3 = 24.3 ohms)
100 ohms ............First three digits are significant, fourth digit represents number of zeros to follow (example: 8252 = 82.5k ohms).
For 5 % Tolerance:
<10 ohms .............“R” designates decimal point (example: 4R7 = 4.7 ohms)
10 ohms ..............First two digits are significant, third digit represents number of zeros to follow (example: 474 = 470k ohms; 000 = Jumper).
