DESCRIPTION

A uniform alloy film is deposited on a high grade ceramic body (Al2O3) and achieved the desired temperature coefficient by

annealing. Nickel plated termination caps are firmly attached on the ceramic body. It is achieved the target value by

smoothly cutting a helical groove in the resistive layer without damaging the ceramic body. The resistive film is covered by

epoxy molding compound designed for electrical, mechanical and climatic protection. For environmental soldering issue,

Nickel plated terminations receive a final pure tin on it. Four color code rings designate the resistance value in accordance

with IEC 60062.

FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E192 series for resistors with a tolerance of ±1%,

±0.5%, ±0.25%, ±0.1%. The values of the E192 series are in accordance with “IEC publication 60063”.

DERATING

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

MOUNTING

Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by

automatic placement systems.

Cylindrical placement can be on ceramic rods 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 cylindrical 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 within lead-free solder bath. The

test condition for no leaching is 260°C for 30 seconds. Typical examples of soldering profile and condition that

provide reliable joints without any damage are given in Fig 3. and Table 1.
