Surface Mount Fuses
UN1206FS Series Fuse
UN1206FSSeriesFuse
Description
UN1206FS Series are the fuses set the industry
standard for performance, reliability and quality. The
solder‐free design provides excellent on‐off and
temperature cycling characteristics during use and also
makes our SMD fuses more heat and shock tolerant
than typical subminiature fuses.
Features
● Rapid interruption of excessive current
● Compatible with reflow and wave solder
● Ceramic and glass construction
● One time positive disconnect
● Lead Free and Halogen free material

* DC Interrupting Rating (Measured at rated voltage, time constant of less than 50 microseconds, battery source)
* DC Cold Resistance are measured at <10% of rated current in ambient temperature of 25°C
* Typical Pre-arching I2t are measured at 10In Current
