NFR25, NFR25H
Vishay BCcomponents
Fusible, Non-Flammable Metal Film Leaded Resistors
FEATURES
• Technology: Metal film
• Overload protection without risk of fire
• Wide range of overload currents (refer Fusing
Characteristics graphs)
DESCRIPTION
• Lead (Pb)-free solder contacts
A homogeneous film of metal alloy is deposited on a high
grade ceramic body. After a helical groove has been cut in
the resistive layer, tinned connecting wires of electrolytic
copper are welded to the end-caps. The resistors are coated
with a grey, flame retardant lacquer which provides
electrical, mechanical, and climatic protection. The
encapsulant is resistant to all cleaning solvents in
accordance with IEC 60068-2-45.
• Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
• Compatible to RoHS directive 2002/95/EC
APPLICATIONS
• Audio
• Video

MARKING
The nominal resistance and tolerance are marked on the
resistor using four colored bands in accordance with
IEC 60062, marking codes for resistors and capacitors.
For ease of recognition a fifth ring is added, which is violet
for type NFR25 and white for type NFR25H.
FUNCTIONAL PERFORMANCE,
PRODUCT CHARACTERIZATION
Standard values of nominal resistance are taken from the
E24 series for resistors with a tolerance of ± 5 %.
The values of the E24 series are in accordance with
IEC 60063.
OUTLINES
The length of the body (L1) is measured by inserting the
leads into holes of two identical gauge plates and moving
these plates parallel to each other until the resistor body is
clamped without deformation (IEC 60294).

FUSING CHARACTERISTICS
The resistors will fuse without the risk of fire and within an indicated range of overload. Fusing means that the resistive value of
the resistor increases at least 100 times.
The fusing characteristic is measured under constant voltage.

TESTS AND REQUIREMENTES
Essentially all tests are carried out in accordance with
IEC 60115-1 specification, category LCT/UCT/56 (rated
temperature range: Lower category temperature, upper
category temperature; damp heat, long term, 56 days).
The tests are carried out in accordance with IEC 60068-2-xx
test method, “Recommended basic climatic and
mechanical robustness testing procedure for electronic
components” and under standard atmospheric conditions
according to IEC 60068-1, 5.3.
www.vishay.com
7
In the Test Procedures and Requirements table the
tests and requirements are listed with reference to the
relevant clauses of IEC 60115-1 and IEC 60068-2-xx test
methods. A short description of the test procedure is also
given. In some instances deviations from the IEC
recommendations were necessary for our method of
specifying. For inflammability requirements reference is
made to IEC 60115-1.
All soldering tests are performed with mildly activated flux.
