Fusible Thin Film Chip Resistors
M25SI fusible thin film chip resistors are designed for
overload protection in modern professional electronics.
Typical applications include automotive, telecommunication
and industrial equipment.
FEATURES
• Metal film on high quality ceramic
• Special protective top coat
• Flame retardant
• Sn solder contacts on Ni barrier layer
• Fusible resistor for constant voltage
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
Notes
(1) Please refer to APPLICATION INFORMATION below.
(2) Tolerance 1 % on request.
APPLICATION INFORMATION
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal
resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted
film temperature is not exceeded.
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.

Note
• A suitable low thermal resistance of the circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors
within the specified limits. Please consider the application note “Thermal Management in Surface-Mounted Resistor Applications”
(www.vishay.com/doc?28844) for information on the general nature of thermal resistance.

DESCRIPTION
Production is strictly controlled and follows an extensive
set of instructions established for reproducibility. A
homogeneous film of metal alloy is deposited on a high
grade ceramic substrate Al2O3. Specially designed inner
contacts are deposited on both sides. A special laser is used
to achieve the target value by smoothly cutting a meander
groove in the resistive layer without damaging the ceramics.
The resistor elements are covered by a protective coating
designed for 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. Only accepted products are
laid directly into the paper tape in accordance with
IEC 60286-3 Type 1a (1).
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic
soldering using wave, reflow or vapor phase as shown in
IEC 61760-1 (1). The encapsulation is resistant to all
cleaning solvents commonly used in the electronics
industry, including alcohols, esters and aqueous solutions.
The use of conformal coating is not permitted. 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.

TESTS AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
EN 60115-1, generic specification
EN 60115-8 (successor of EN 140400), sectional
specification
IEC 60068-2-xx, test methods
The table presents only the most important tests, for the full
test schedule refer to the documents listed above. However,
some additional tests and a number of improvements
against those minimum requirements have been included.
The testing also covers most of the requirements specified
by EIA/ECA-703 and JIS-C-5201-1.
The tests are carried out under standard atmospheric
conditions in accordance with IEC 60068-1, 4.3, whereupon
the following values are applied:
Temperature: 15 °C to 35 °C
Relative humidity: 25 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
A climatic category LCT / UCT / 56 is applied, defined by the
lower category temperature (LCT), the upper category
temperature (UCT), and the duration of exposure in the
damp heat, steady state test (56 days).
The components are mounted for testing on printed circuit
