Current ratings range from 0.5A to 6.3A with voltage ratings of 63VDC and 32VAC. The devices have a breaking capacity of 63A at rated voltages and an operating temperature range of -55°C to +90°C.
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 (3.2mm x 1.6mm 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 IEC 60286-3.
