ORDERING EXAMPLE
The ordering code for an AC0402
chip resistor, value 100 KΩ with
± 1% tolerance, supplied in 7-inch
tape reel is: AC0402FR-07100KL.
NOTE
1. All our R-Chip products are RoHS
compliant and Halogen free. "LFP" of the
internal 2D reel label states "Lead-Free
Process".
2. On customized label, "LFP" or specific
symbol can be printed.
3. AC series with ±0.5% tolerance is also
available. For further information, please

CONSTRUCTION
The resistors are constructed on top of an automotive grade ceramic body. Internal metal electrodes are added at
each end and connected by a resistive glaze. The resistive glaze is covered by a protective glass.
The composition of the glaze is adjusted to give the approximately required resistance value and laser trimming of this
resistive glaze achieves the value within tolerance. The whole element is covered by a protective overcoat. Size 0603 and
bigger is marked with the resistance value on top. Finally, the two external terminations (Ni / matte tin) are added, as
shown in Fig.8.
