Model
(CR = Chip Resistor)
Size
• 0402
Resistance Tolerance
F = ±1 % ............Used with “X” TCR code only for values from 10 ohms through 1 megohm.
J = ±5 % ..............Used with “W” TCR code for values from 10 ohms through 5.6 megohms. Used with “/” TCR code for zero ohm (jumper)
......................and for values from 1 ohm through 9.1 ohms.
TCR (ppm/°C)
X = ±100 ..............Used with “F” Resistance Tolerance code only for values from 10 ohms through 1 megohm.
W = ±200 ..............Used with “J” Resistance Tolerance code only for values from 10 ohms through 5.6 megohms.
/ = -250 to +500 ..Used with “J” Resistance Tolerance code only for zero ohm (jumper), and for values from 1 ohm through 9.1ohms.
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).
