I²t value is an indispensable technical index for aR semiconductor fuses, which is used to evaluate the energy bearing capacity of fuses in short-circuit protection.
In actual testing, different rated current multiples correspond to different test environments. Low multiple current is used for temperature rise inspection, and high multiple short-circuit current is used for I²t value detection.
Standard test wires shall be matched according to fuse current level to ensure accurate test data. Excessively thick or thin wires will cause deviation of arc time and I²t data.
All EssFuse semiconductor fuses are tested in strict accordance with industry standards, with complete official I²t parameter sheets, suitable for new energy vehicles, photovoltaic energy storage and industrial frequency conversion equipment.
