CRM2512 - High Power Current Sense Chip Resistors

How to Order

CRM 2512 - F X - R100 E LF

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 (example: R100 = 0.100 ohm)

• 1% Tolerance:

<100 ohms ...........“R” represents 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)

• 5% Tolerance:

<10 ohms .............“R” represents 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)

0 ohm Jumper ......“000”

Packaging

• E = 4000 pieces per 180 mm (7 inch) reel

Termination

• LF = Tin-plated (RoHS Compliant)
