Model
(CRM = Precision Chip Resistor)
Size
2512 = 2512 Size
Resistance Tolerance
• F = ±1 %.................Use with “X” TCR code
• J = ±5 % .................Use with “W” TCR code for values from 1 ohm through 1 megohm
Use with “X” TCR code for values from 0.047 ohm through 0.91 ohm
Use with “/” TCR code for 0 ohm (Jumper)
TCR (PPM/°C - See Electrical Characteristics chart)
• W = ±200 PPM/°C
• X = ±100 PPM/°C
• / = Jumper
Resistance Value
• 1 % or 5 % Tolerance:
R <1 ohm..............“R” represents decimal point followed by three significant digits
≥10 ohms .............First two digits are significant, third digit represents number of zeros to follow
(example: 474 = 470K ohms)
0 ohm Jumper ......“000”
Packaging
• E = 4000 pieces per 180 mm (7 inch) reel
Termination
• LF = Tin-plated (RoHS Compliant)
