Maximum protection from a minimalist
fuse
Fuses provide secondary overcurrent protection in power inverters and low-voltage power supplies in an extremely small 1206 package.
Now available from Arrow, the Schurter USI 1206 is the industry's first IEC-approved Universal Modular Fuse (UMF) in a 1206 footprint In addition to conformance to IEC60127-4/2, the device bears international approvals by cURus, METI and CCC

Single-chip control of PC Card interfaces
Arrow Electronics has a family of compact, highly integrated and power-efficient PC Card controllers that will help designers to lower component count, save space and reduce power consumption.
The new fuse series has high melting I2t values, which provides greater withstand against inrush or pulse currents.
In lower overcurrent conditions its opening time is comparable with 1206 time-delay types according to UL; but it also responds very quickly to higher overcurrents in the event of a fault condition.
Current ratings range from 0.5 to 6.3A with voltage ratings of 63V DC and 32V AC.
The devices have a breaking capacity of 63A at rated voltages and an operating temperature range of -55 to +90C.
The USI series is designed to provide secondary overcurrent protection (OCP) in power inverters and low-voltage power supplies in an extremely small 1206 package (3.2 x 1.6 x 0.6mm).
It is also suitable for protection of integrated display and storage subsystems, portable medical devices and sensor-rich in-car electronics, where reliability of performance is critical.
The thin film technology process used to produce the fuse yields very predictable and stable performance results, as each fuse passes through a testing procedure in order to qualify for use in the most sensitive electronic systems.
The device supports lead (Pb)-free reflow soldering or vapour phase processes and is RoHS compliant according to EU Directive 2002/95/EG.
It is supplied taped and reeled according to IEC60286-3.
