The UST 1206, the first SMT chip fuse in the 1206 format, was introduced by SCHURTER in 2008. This especially compact and powerful fuse has been quite popular ever since. SCHURTER is adding even more powerful UST 1206 models with rated currents of up to 35 A to its product line in response to several customer requests.
The SCHURTER UST 1206, a chip fuse with a “slow-blow” function for surface mounting. When the inrush current peaks above the rated current, the fuse does not trip immediately due to its high melting integral I2t. This is essential in many industrial applications, including motors and power converters.
UL 248-14 Characteristic
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.
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 further variants. The rated voltage is 32 VAC and 63 VDC respectively. The fuse can be operated from -55 °C to +90 °C.
Application Areas
The SCHURTER UST 1206 is ideally suited for all applications in secondary overcurrent protection where the current requirement is particularly high even at low voltages.
