FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken

from the E96 & E24 series for resistors with a

tolerance of ±1%, ±5%. 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 their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by

automatic placement systems.

Chip placement can be on ceramic substrates and printed-circuit boards (PCBs).

Electrical connection to the circuit is by individual soldering condition.

The end terminations guarantee a reliable contact.

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

235°C during 2 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.
