Note
• 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.

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 body. The fuse 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 performed on 100 % of the
individual fuses. Only accepted products are laid directly
into the paper tape in accordance with IEC 60286-3.
APPROVALS
The fuses are tested in accordance with the following
standards:
• IEC 60127-1
• IEC 60127-4
• UL 248-14
• IEC 60068 series
Approval of conformity is indicated by the UMF Logo on the
package label. Recognition by Underwriter Laboratories Inc.
is indicated by the UL logo on the package label.
ASSEMBLY
The fuses 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 fuses are RoHS compliant, the
pure tin plating provides compatibility with lead (Pb)-free
and lead-containing soldering processes. The immunity of
the plating against tin whisker growth has been proven
under extensive testing. Solderability is specified for 2 years
after production or re-qualification. The permitted storage
time is 20 years.
All products comply with the JIG 101 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)
• 2011/65/EU Restriction of the use of Hazardous
Substances Directive (RoHS)
• 2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)

TEST AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
IEC 60127-1, Miniature fuse - Part 1: Definitions for
miniature fuses and general requirements for miniature
fuse-links
IEC 60127-4, Universal Modular Fuse Links (UMF)
UL 248-14, Low voltage fuses - Part 14: Supplemental
fuses
For the full test schedule refer to the documents listed
above. The testing also covers most of the requirements
specified by METI and CCC.
The tests are carried out under standard atmospheric
conditions in accordance with IEC 60068-1, 5.3. Climatic
category LCT/UCT/56 (rated temperature range: Lower
category temperature, upper category temperature; damp
heat, long term, 56 days) is valid.
Unless otherwise specified the following values apply:
Temperature: 15 °C to 35 °C
Relative humidity: 45 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
The components are mounted for testing on printed-circuit
boards in accordance with IEC 60127-4, unless otherwise
specified.
The requirements stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of IEC 60127-1 and IEC 60127-4
respectively. However, some additional tests and a number
of improvements against those minimum requirements have
been included.
