ceramic substrate to form the resistive layer. Pre-contacts are
printed on both sides of the substrate. The resistors are laser
trimmed to the target value. The resistor elements are
covered by glass and a protective coating combined for
superior electrical, mechanical and climatic protection. The
prepared terminations receive an electroplating of PbSn
solder on nickel plating. A three or four digit code
designates the nominal resistance value.

APPLICATIONS
The result of the determined production is verified by a final
test performed on 100% of the individual chip resistors.
Only accepted products are laid directly into the paper tape
according to
IEC 60286-3.
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic soldering
using wave, reflow or vapour phase. The encapsulation is
resistant to all cleaning solvents commonly used in the
electronics industry, including alcohols, esters and aqueous
solutions.
The resistors are tested in accordance with
IEC 60115-1
and
IEC 60115-8.
This product family of thick film flat chip resistors is
completed by
Zero Ohm Jumpers.

•
Consumer electronics.
DESCRIPTION
DCS 0402, DCT 0603, DCU 0805 and DCA 1206 thick film
chip resistors are made for all general purpose
applications. They are typically used in the production of
office automation equipment and consumer electronics.
The production is performed in a mass volume production
site. A thick film is screen printed on a high grade alumina

ORDERING INFORMATION
DCS 0402; DCT 0603;
DCU 0805; DCA 1206
Components may be ordered by using either a simple clear text ordering code, see “Type description and ordering code”
or BCcomponents’ unique 12NC.
Numeric Ordering code (12NC)
•
The resistors have a 12-digit ordering code starting with 2312.
•
The subsequent 4 digits indicate the resistor type, specification and packaging; see Table 2.
•
The remaining 4 digits indicate the resistance value:
– The first 3 digits indicate the resistance value.
– The last digit indicates the resistance decade in accordance with Table 3.
