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 1206, 0805 size
For E24/E96 series, each resistor is marked with a four digits code on the protective coating to designate the
nominal resistance value. For non E24/E96 series, no marking is applied!

FUNCTIONAL DESCRIPTION
Product characterization
Standard values of nominal resistance are taken from the E192 & E24 series for resistors with a tolerance of
1%, 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.
Storage and Handling Condition:
1.
2.
Products are recommended to be used up within two years. Check solderability in case
shelf life extension is needed.
To store products with following condition:
Temperature : 5 to 40
Humidity
: 20 to 70% relative humidity
Caution:
a. Don’t store products in a corrosive environment such as sulfide, chloride gas, or acid. It
may cause oxidation of electrode, which easily be resulted in poor soldering.
b. To store products on the shelf and avoid exposure to moisture.
c. Don’t expose products to excessive shock, vibration, direct sunlight and so on.
