SMT chip fuse portfolio in 1206 format expanded

Schurter launched the first SMT chip fuse in the 1206 format in 2008: the UST 1206. Since then, this extremely compact and powerful fuse has been very popular. In response to several customer requests, the company is expanding its product portfolio with even more powerful versions of the UST 1206 with rated currents of up to 35A.

The new device is a surface-mounted chip fuse with a 'slow-blow' characteristic. This means it has a high melting integral I2t, which means the fuse does not trip immediately at inrush current peaks higher than the rated current. This is very important in many industrial applications (e.g. motors and power converters).

The chip fuse 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 approximately 70% of the rated current.

Previous versions of the chip fuse had a maximum rated current of 25A. This range will be increased to 30A and 35A with two further variants. The rated voltage is 32VAC and 63VDC, respectively. The fuse can be operated from -55C to +90C.

The SCHURTER UST 1206 is ideal for all applications in secondary overcurrent protection where the current requirement is especially high, even at low voltages.
