INTRODUCTION
Data in data sheets is presented - whenever possible
-according to a 'format', in which the following
chapters are stated:
The chapters listed above are explained in this
section “Introduction Thick Film Chip Resistors”, with
detailed information in the relevant data sheet.
Chapters “Mounting”, “Packing”, and “Marking” are
detailed in separate sections.
DESCRIPTION
All thick film types of chip resistors have a
rectangular ceramic body. The resistive element is a
metal glaze film. The chips have been trimmed to the
required ohmic resistance by cutting one or more
grooves in the resistive layer. This process is
completely computer controlled and yields a high
reliability. The terminations are attached using either
a silver dipping method or by applying nickel
terminations, which are covered with a protective
epoxy coat, finally the two external terminations
(matte tin on Ni-barrier) are added.
The resistive layer is coated with a colored
protective layer. This protective layer provides
electrical, mechanical and/or environmental
protection - also against soldering flux and cleaning
solvents, in accordance with “MIL-STD-202G”, method
215 and “IEC 60115-4.29”. Yageo thick film chip
resistor is flameproof and can meet “UL94V-0”.

FUNCTIONAL DESCRIPTION
The functional description includes: nominal
resistance range and tolerance, limiting voltage,
temperature coefficient, absolute maximum
dissipation, climatic category and stability.
The limiting voltage (DC or RMS) is the maximum
voltage that may be continuously applied to the
resistor element, see “IEC publications 60115-8”.
The laws of heat conduction, convection and
radiation determine the temperature rise in a
resistor owing to power dissipation. The maximum
body temperature usually occurs in the middle of the
resistor and is called the hot-spot temperature.
In the normal operating temperature range of chip
resistors the temperature rise at the hot-spot, .T, is
proportional to the power dissipated: ∆T = A × P.
The proportionally constant ‘A’ gives the
temperature rise per Watt of dissipated power and
can be interpreted as a thermal resistance in K/W.
This thermal resistance is dependent on the heat
conductivity of the materials used (including the
PCB), the way of mounting and the dimensions of the
resistor. The sum of the temperature rise and the
ambient temperature is:
The stability of a chip resistor during endurance tests
is mainly determined by the hot-spot temperature
and the resistive materials used.
