Suitable for both flow and reflow soldering

Reduction of assembly costs and matching

with placement machines

Standard: 2%, 5%, 10%---E 24 series

1%---E 96 series

Ordering Procedure: (Ex.: 1206, 1/4W-S, 5%, 10Ω, T/R-5000)

Resistor Type:

Chip Resistor types as follows:

0402, 0603, 0805, 1206, 1210, 2010,

2512, 2D02, 4D02, 4D03, 10P8, 16P8

Resistance Value:

•

E-24 series:

1 digit is “0”

2 & 3 digits are significant

figures of the resistance

4 indicate the number of zeros

E-96 series:

1 to 3 digits are significant figures

of the resistance

4 digit indicate the number of zeros.

“J” ~ 0.1, “K” ~ 0.01, “L” ~ 0.001

Ex.

012J ~ 1Ω2, 226K ~ 2Ω26

Jumper :

use “0” for 1 to 4 digits

•
