•
TCT 0603, TCU 0805 and TCA 1206 trimmable flat chip
resistors are best suited whenever stable circuit adjustment
is required and potentiometers will be either too expensive,
too unstable or too large. The trimming is done directly on the
printed-circuit board (PCB) using a state of the art laser
trimming system e.g. with YAG or CO
2
laser source. Typical
applications include any type of electronic sensors,
oscillators or electronic circuits which have to be trimmed to
certain functional parameters after PCB assembly.

Notes
(1)
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded.
(2)
All given figures are valid for the untrimmed resistor
•
These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over
operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

REFLOW SOLDERING
Note
• The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of
power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the
reliability of the assembly.
Specified power rating above 125 °C requires dedicated heat-sink pads, which depend on board materials.
The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x, or in
publication IPC-7351. They do not guarantee any supposed thermal properties, particularly as these are also strongly influenced by many other
parameters.
Still, the given solder pad dimensions will be found adequate for most general applications, e.g. those referring to “standard operation mode”.
Please note however that applications for “power operation mode” require special considerations for the design of solder pads and adjacent
conductor areas.

DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A newly
developed cermet layer is deposited onto a high-grade
(Al
2
O
3
) ceramic substrate and conditioned to achieve the
desired temperature coefficient. Pre-contacts are built on
both sides of the substrate. The resistor elements are
covered by glass for superior electrical, mechanical and
climatic protection. The terminations receive a final pure
tin-on-nickel plating.
The result of the determined production is verified by an
extensive testing procedure performed on 100 % of the
individual chip resistors. Only accepted products are laid
directly into the paper tape in accordance with
IEC 60286-3
(3)
.
The resistors are RoHS compliant; the pure tin plating
provides
compatibility
with
lead
(Pb)-free
and
lead-containing soldering processes. Solderability is
specified for 2 years after production or requalification. The
permitted storage time is 20 years. The immunity of the
plating against tin whisker growth has been proven under
extensive testing.
All products comply with the
GADSL
(1)
and the
CEFIC-EECA-EICTA
(2)
list of legal restrictions on
hazardous substances. This includes full compliance with
the following directives:
• 2000/53/EC End of Vehicle life Directive (ELV) and
Annex II (ELV II)
• 2002/95/EC Restriction of
Substances directive (RoHS)
the
use
of
Hazardous
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic soldering
using wave, reflow or vapour phase as shown in
IEC 61760-1
(3)
. The encapsulation is resistant to all cleaning
solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
suitability of conformal coatings, if applied, shall be qualified
by appropriate means to ensure the long-term stability of the
whole system.
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
APPROVALS
The resistors are tested in accordance with
EN 140401-802
which refers to
EN 60115-1
and
EN 140400.
The detail
specification refers to the climatic category 55/125/56, which
relates to the “Standard operation mode” of this datasheet.
Vishay BEYSCHLAG has achieved
“Approval
Manufacturer”
in accordance with
EN 100114-1.
