This IEC quick-acting (F) chip fuse series USI 1206, Universal Modular Fuse (UMF) is approved according to IEC 60127-4/2, and bears international approvals by cURus, METI, and CCC. The new fuse series has high melting I2t values, which provides greater withstand against high inrush or pulse currents. Its opening time compares to 1206 time-delay types according to UL in lower overcurrent conditions, but responds very quickly to higher overcurrents in the event of a fault condition. Current ratings range from 0.5 to 6.3 A with voltage ratings of 63 VDC and 32 VAC.
