Product Description
0402 Resettable Surface Mount Fuses Overview
As consumer electronics continue to miniaturize, electronic components must follow suit. Our 0402 resettable surface mount fuses represent the smallest form factor available in the market, providing reliable overcurrent protection while saving valuable PCB space.
Key Features
- RoHS compliant, lead-free and halogen-free construction
- Fast response to fault currents for enhanced protection
- Compact 0402 design maximizes board space utilization
- Low resistance and low-profile design
- Compatible with high-temperature soldering processes
- Industry's smallest PPTC fuse compatible with high-temperature solders
- 10,000 pieces per reel with Tape & reel packaging per EIA481-1
Applications
Ideal for USB peripherals, disk drives, CD-ROMs, motherboard and peripheral protection, PDAs, digital cameras, game console port protection, tablet and notebook PCs, and e-readers.

Parameter Definitions
V max = Maximum operating voltage device can withstand without damage at rated current (Imax).
I max = Maximum fault current device can withstand without damage at rated voltage (V max).
I hold = Hold Current. Maximum current device will not trip in 25°C still air.
I trip = Trip Current. Minimum current at which the device will always trip in 25°C still air.
Pd = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.
Ri min/max = Minimum/Maximum device resistance prior to tripping at 25°C.
R1max = Maximum device resistance is measured one hour post reflow.
I max = Maximum fault current device can withstand without damage at rated voltage (V max).
I hold = Hold Current. Maximum current device will not trip in 25°C still air.
I trip = Trip Current. Minimum current at which the device will always trip in 25°C still air.
Pd = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.
Ri min/max = Minimum/Maximum device resistance prior to tripping at 25°C.
R1max = Maximum device resistance is measured one hour post reflow.
CAUTION: Operation beyond the specified ratings may result in damage and possible arcing and flame.
