FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E24/E96 series for resistors with a tolerance of 5%

& 1%. The values of the E24/E96 series are in accordance with “IEC publication 60063”

Derating

The power that the resistor can dissipate depends on the operating temperature; see Fig.2

Figure 2. Maximum dissipation in percentage of rated power

As a function of the ambient temperature

MOUNTING

Due to its rectangular shape and ultra small size, Surface Mountable Resistors 01005 should be carefully

handling by automatic placement systems. 01005 chip can withstand pressure force min. 1.9N by applying

φ0.18 pressure jig as shown drawing below. For mounting application, please contact Walsin group for details.

SOLDERING CONDITION

The robust construction of chip resistors allows them to

be completely immersed in a solder bath of 260C for 10

seconds. Therefore, it is possible to mount Surface

Mount Resistors on one side of a PCB and other

discrete components on the reverse (mixed PCBs).

Surface Mount Resistors are tested for solderability at

245C during 3 seconds. The test condition for no

leaching is 260C for 30 seconds. Typical examples of

soldering processes that provide reliable joints without

any damage are given in Fig 3.
