Unlike the other chip fuses the UST 1206 has the Time-lag characteristic and provides high melting I²t values. The current ratings range from 7A to 25A with voltage ratings up to 63VDC and 32VAC. The device provides a breaking capacity of up to 400A at a defined voltage. The UST 1206 fuse series is a cost-effective solution for applications where high inrush current and on/off cycling is present. It is designed to supply secondary overcurrent protection in products where power consumption is high at a low voltage level such as 5 or 12VDC.
