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:
