UST 1206 SMD Fuses

The SCHURTER UST 1206 is a slow blow, surface mount chip fuse with a high melting integral I²t, so the fuse does not trip immediately at inrush current peaks higher than the rated current. This feature is important in many industrial applications, e.g., motors and 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 V_AC and 63 V_DC. The fuse can be operated from -55°C to +90 °C.

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.
