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. ## Vishay Beyschlag ## **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) ## **FUNCTIONAL PERFORMANCE** **==> picture [346 x 295] intentionally omitted <==** **----- Start of picture text -----**

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. |**TEST PROCEDURES AND REQUIREMENTS**|**TEST PROCEDURES AND REQUIREMENTS**|**TEST PROCEDURES AND REQUIREMENTS**|**TEST PROCEDURES AND REQUIREMENTS**|**TEST PROCEDURES AND REQUIREMENTS**|**TEST PROCEDURES AND REQUIREMENTS**|**TEST PROCEDURES AND REQUIREMENTS**| |---|---|---|---|---|---|---| |**IEC**
