DESCRIPTION

The resistors are constructed in a high grade ceramic body (aluminum oxide). Internal metal electrodes are

added at each end and connected by a resistive layer that is applied to the top surface of the substrate. The

composition of the resistive layer is adjusted to give the approximate resistance required and the value is

trimmed to nominated value within tolerance which controlled by laser trimming of this resistive layer.

The resistive layer is covered with a protective coat. Finally, the two external end terminations are added. For

environmental soldering issue, the outer layer of these end terminations is a Lead-free solder .

4-digits marking for 2512, 2010, 1210, 1206, 0805 size

For E24+E96, each resistor is marked with a four digits code on the protective coating to designate the

nominal resistance value. For values below 976 the R is used as a digit. For values of 100 or greater, the

first 3 digits are significant, the fourth digit indicates the number of multiple to follow.

FUNCTIONAL DESCRIPTION

Product characterization

Standard values of nominal resistance are taken from the E192 & E24 series for resistors with a tolerance of

1.0%, 0.5%, 0.25%, 0.1%, 0.05%.

The values of the E24/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.

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.
