ORDERING INFORMATION - GLOBAL PART NUMBER
Part number is identified by the series name, size, tolerance, packaging
type, temperature coefficient, taping reel and resistance value.
SCOPE
This specification describes AC0201
to AC2512 chip resistors with lead-
free terminations made by thick film
process.
APPLICATIONS
All general purpose applications
Car electronics, industrial
application
FEATURES
AEC-Q200 qualified
Moisture sensitivity level: MSL 1
AC series soldering is compliant
with J-STD-020D
Halogen free epoxy
RoHS compliant
- Products with lead-free
terminations meet RoHS
requirements
- Pb-glass contained in electrodes,
resistor element and glass are
exempted by RoHS
Reduce environmentally
hazardous waste
High component and equipment
reliability
The resistors are 100% performed
by automatic optical inspection
prior to taping.
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
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 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.
