SCOPE
ORDERING INFORMATION - GLOBAL PART NUMBER
This specification describes AC0612
to AC1225 chip resistors with leadfree terminations made by thick film
process.
Part number is identified by the series name, size, tolerance, packaging
type, temperature coefficient, taping reel and resistance value.
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.

There are 2~4 digits indicated the resistance value. Letter R/K/M is decimal point, no
need to mention the last zero after R/K/M, e.g.1K2, not 1K20.
Detailed coding rules of resistance are shown in the table of “Resistance rule of
global part number”.

O RDERING EXAMPLE
The ordering code for an AC0612
chip resistor, value 100 KΩ with
± 1% tolerance, supplied in 7-inch
tape reel is: AC0612FR-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 a high-grade
ceramic body. Internal metal electrodes are added at each
end and connected by the resistive glaze. The resistive
glaze is covered by a leadfree glass. The composition of
the glaze is adjusted to give the approximate required
resistance value and laser trimming of this resistive glaze
achieves the value inside tolerance. The whole element is
covered by a protective overcoat. Size 0508 and bigger is
marked with the resistance value on top. Finally, the two
external terminations (Ni / matte tin) are added. See fig.3.
