UST 1206 Chip Fuse – Now Up to 35A

In 2008, SCHURTER launched the first SMT chip fuse in the 1206 format: the UST 1206. Since then, this particularly compact and powerful fuse has enjoyed great popularity. Due to popular demand, SCHURTER is expanding its product portfolio with even more powerful versions of the UST 1206 with rated currents of up to 35 A.

The SCHURTER UST 1206 is a surface-mounted chip fuse with a “slow-blow” characteristic. This means that it has a high melting integral I2t, which means that the fuse does not blow immediately at current peaks higher than the rated current. This is of great importance in many industrial applications (e.g. motors, power converters).

UL 248-14 Characteristic
The UST 1206 is designed for UL 248-14 characteristics. For such fuses, the rated current corresponds to the current that interrupts the current after a few hours. The maximum current that may flow continuously without the fuse being tripped is approximately 70% of the rated current.

New variants up to 35 A
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 new variants. The rated voltage is 32 VAC and 63 VDC respectively. The fuse can be used from -55 °C to +90 °C.

Areas of application
The SCHURTER UST 1206 is ideal for all applications in secondary overcurrent protection where current requirements are particularly high, even at low voltages.
