and halogen-free

• Fast response to fault

currents

• Low resistance

• Low-prole

• Compatible with high

temperature solders

• Compact design saves

board space

Applications

• USB peripherals

• Disk drives

• CD-ROMs

• PC motherboards - plug

and play protection

• Mobile phones - battery

and port protection

• PDAs / digital cameras

• Game console port

protection
