Chip Fuse Boasts Several Capabilities


SCHURTER’s UAI 1206 chip fuse offers pulse withstand and temperature resistant capabilities, together with time-lag characteristics. The device suits applications where durability and maximum reliability are required in a small footprint. According to the company, conventional fuses have a sort of memory. If they are exposed to pulse-shaped current peaks and high temperature fluctuations, their properties change. Every pulse makes the fuse a little weaker, every temperature fluctuation a little more susceptible.


This is not so with the UAI 1206. Because of the special fuse construction, dubbed by SCHURTER as “trace in air” technology, the UAI’s ability to resist current pulses smaller than the melting integral (I2t) is thereby increased exponentially. The component has practically no de-rating to the usual extent. Additionally, the unique design of the fuse body also dampens temperature fluctuations to a high degree.


Designed to UL 248-14, the UAI 1206 was originally developed specifically for automotive applications. It is offered in two versions with rated currents of 5.3A and 7.5A at 32 Vdc. Rated breaking capacity is 100A. The UAI 1206 meets all requirements according to AEC-Q200. The fuse is also sealed against potting compound for use in intrinsically safe applications, such chemically exposed equipment like those found in the oil and gas, mining, first response, lighting, and medical industries.


Pricing for the UAI 1206 is $.285 each/1,000 piece reels. For more insights, checkout the UAI 1206 datasheet, call 800-848-2600, and/or email [email protected]
