0603 disposable chip fuse
实物图片：
Features产品特点：
• Compatible with leadfree solders and higher temperature profiles.
• High performance materials provide improved performance in elevated ambient temperature applications.
• Marked on top surface with code to allow amp rating identification without testing.
• Low profile for height sensitive applications.
• Flat top surface for pickand-place operations.
• Element covering material is resistant to industry standard cleaning operations.
• Mounting pad and electrical performance is identical to Littelfuse 431 and 434 Series products.
• Alloy based element construction provides superior inrush withstand characteristics (I2t) over ceramic
or glass based 0603 fuse products.
Applications产品应用：
Secondary protection for space constrained applications:
• Cell phones

1. Measured at 10% of rated current, 25ºC. 2. Measured at rated voltage.
Temperature Rerating Curve
Note:
1. Derating depicted in this curve is in addition to the standard derating of 25% for
continuous operation.
Example:For continuous operation at 70 degrees celsius, the fuse should be deratedas follows:
I = (0.75)(0.80)IRAT = (0.60)IRAT
2. The temperature derating curve represents the nominal conditions. For questions about temperature derating curve,
please consult our technical support for assistance.
