†This dimension determines the number of conductors which may pass under the surface mounted device.
Construction
Thick film resistor material, overglaze and organic protection
are screen printed on a 96% alumina substrate.
Solderability
Wrap-around terminations have an electroplated nickel barrier
and solder coating, this ensures excellent ‘leach’ resistance
properties and solderability. They will withstand immersion in
solder at 26±°C for 3± seconds.
Terminations
Planar (or single-sided) termination is gold and suitable for
wire-bonding; wrap-around is suitable for soldering.
Marking
All relevant information recorded on the primary package or reel.

Application Notes
Operating Temperature Range
Packaging
The chips themselves can operate at a maximum temperature
of 155°C (see performance claims above). For soldered chips,
the joint temperature should not exceed 110°C. This
condition is met when the stated power levels at 70°C are
used.
Wrap-around Termination
Chip resistors are supplied taped and reeled on standard
8mm tape to IEC 286-3.
Quantity per reel; 3000 max.
Mounting
Planar Terminations
Resistor chips are supplied in waffle packs.
This chip resistor is ideally suited for handling by automatic
methods due to its rectangular shape and the small
dimensional tolerances. Electrical connection to a ceramic
substrate or to a printed circuit board can be made by wire
bonding (eg suffix ‘G’ in CR0805G) or by reflow soldering of
wrap-around terminations (eg suffix ‘F’ in CR0805F).
The ‘F’ terminations provide good leach properties and ensure
reliable contact. Due to the robust construction the resistor
chip can be immersed in the solder bath for 30 seconds at
260°C. This enables the resistor to be mounted on one side
of a printed circuit board and other wire-leaded components
on the other side.

For CECC released product state on order the CECC number. Example: CR2512F-10KFI CECC40401-008
For SnPb finish instead of Pb-free replace the packing suffix with PB. Example: CR2512F-10KFPB
For zero-ohm jumper chips use the dummy value & tolerance code R005J
