The UST 1206 is a chip fuse for surface mounting with a “slow-blow” characteristic. This means that it has a high melting integral I2t, thanks to which the fuse does not trip immediately at inrush current peaks higher than the rated current. This is of great importance in many industrial applications (e.g. motors, power converters).
The UST 1206 was designed for UL 248-14 characteristics. With such fuse-links, the rated current corresponds to the current that interrupts the current flow after several hours. The maximum current that may flow continuously without the fuse-link tripping is around 70 % of the rated current.
Previous versions of the UST 1206 had a maximum rated current of 25 A. This range will be increased to 30 A and 35 A with two further variants. The rated voltage is 32 VAC and 63 VDC respectively. The fuse can be operated from -55 °C to +90 °C.
