1 Design Registerable! Smallest Surface Mount AC Fuses 470 and 476 Series New Product Introduction December

2 Introducing the 470 & 476 Series Fuses What are they? AC Voltage SMT NANO 2 Subminiature Fuses 470 Series 1206 package 476 Series 2410 package Smallest 125/250Vac rated SMT type Used on primary side circuit protection Solution for AC voltage, compact applications 2

3 Why Use Fuses? Design considerations? Designed to provide protection against faulty over-current loads Protects the downstream components No moving parts to wear out Limit shock threats to human life and property damage Over-current protection devices are essential in electrical systems 3

4 470 & 476 Series Common Applications LED Lighting LCD/LED TVs Notebooks/PCs White Goods Gaming Consoles Power Supply Units 4

5 470 & 476 Series Key Features and Benefits Key Features Surface Mount Type AC Fuse Smallest footprint 470 Series Series 2410 High operating temperature at 125 o C Surge Immunity Capability 470 Series US: ENERGY STAR (1.5A and above ampere rating only) 476 Series Global: IEC ed. (3A and above ampere rating only) Benefits SMT is the trend in compact, spacelimited applications; it also enables higher speed and yield in manufacturing processes Occupies less board space Suitable for high temperature applications such as LED lighting 470 and 476 Series Fuses withstand surge from AC power line and keep LED light bulb/tube working continuously 5

6 470 & 476 Series Advantages Why Choose the 470 & 476 Series? Operate effectively at extreme temperatures, without sacrificing too much on current re-rating Available in the highest number of amperage ratings at the rated voltages Passes ENERGY STAR requirements (470 Series, 1.5A and above ampere rating only) and IEC ed. Surge Immunity test (476 Series, 3A and above ampere rating only), optimal for LED lighting applications Tested extensively to open safely at the specified interrupt ratings especially at 86VDC/10KA 6
