1206 disposable chip fuse
Physical map：
Description：
This 100% Lead-free, RoHS compliant and Halogen-free fuse series has been designed specifically to provide over current protection to circuits that see
high working ambient temperatures (up to 150ºC).
The general design ensures excellent temperature stability and performance reliability.
In addition to this, the high I²t values typical of the Ceramic Fuse family ensure high inrush current withstand capability.
Features：
• Operating Temperature from -55ºC to +150ºC
• 100%Lead-free,RoHS compliant and Halogen-free
• Suitable for both leaded and lead-free reflow /wave soldering
• UltrahighI2t values
Applications：
• Automotive Electronics
• Printers
• LCD Displays
• Servers
• Notebook Computers
• Scanners
• Data Modems
• Hard Disk Drives

Notes:
1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msec.
2. Nominal Resistance measured with < 10% rated current.
3. Nominal Melting I²t measured at 1 msec. opening time.
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
Devices designed to carry rated current for 4 hours minimum. It is recommended that devices be operated continuously at
no more than 80% rated current. See “Temperature Derating Curve”for additional derating information.Devices designed to
be mounted with marking code facing up.
Temperature Derating Curve
Notes:
1. Derating depicted in this curve is in addition to the standard derating of 20% for continuous operation.
Example:
For continuous operation at 75 degrees celsius, the fuse should be derated as follows:I = (0.80)(0.85)IRAT= (0.68)IRAT
