A chip fuse for the highest demands

20 September 2019


The UAI 1206 from SCHURTER is a pulse & temperature resistant chip fuse with slow release characteristics.

SCHURTER Electronics specifically designs chip fuses for low-loss overcurrent protection in secondary circuits. In a range of six different chip sizes from 0402 to 1206, SCHURTER’s chip fuses guarantee compact and effective protection in the event of a fault.

When regular fuses are exposed to pulse-shaped current peaks and high temperature fluctuations, their properties change. Every pulse makes it a little weaker, every temperature fluctuation a little more susceptible. This is not the case with the SCHURTER UAI 1206.

Pulse and temperature resistant
Thanks to the special fuse construction, the resistance to current pulses smaller than the melting integral (I2t) could be massively increased. The UAI 1206 has practically no derating compared to other products of this type. The ingenious design of the fuse body also dampens temperature fluctuations to a high degree. The SCHURTER UAI 1206 is also hermetically sealed against potting compound.

Areas of application
The new chip fuse, which is offered in two versions with rated currents of 5.3 A and 7.5 A, has been specificially developed for automotive applications. The SCHURTER UAI 1206 meets all requirements according to AEC-Q200 regarding Mechanical Shock and Terminal Strength.

However, it is also suitable wherever maximum pulse resistance, thermal resistance and high mechanical loads meet.

Chipfuse range
SCHURTER's range of chipfuses have a cURus approval. The range is halogen-free and RoHS-compliant, therefore they can be used for lead-free soldering processes. The solid constrution of the chipfuses reinforces the resistiveness to vibrations and pulse loads.
