RDERING EXAMPLE
The ordering code for an AC0402
chip resistor, value 100 KX with
±1% tolerance, supplied in 7-inch
tape reel is: AC0402FR-07100KL.
NOTE
1. All our RSMD 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
contact sales.

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 lead-free 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.
