Please also refer to the common precautions for fuses in this catalog. 1. Set the rated current so that the current passing through the Micro Chip Fuses (hereafter called the fuses) under normal conditions is within 70% of the rated current. 2. Do not continuously pass a current exceeding the rated current through the fuses. 3. If a pulse exceeding the rated current is applied, such as a rush current or surge current at power-on, take care not to cause unwanted fusing. Calculate the I2t value of the pulse and check the tolerance to the number of pulses according to the I2t-t characteristic curve before deciding to use the fuses. Before checking the tolerance, consult our sales staff in advance. 4. The fuses are designed to be blown out by a current that is double or greater than the rated current. Ensure that the abnormal current generated when a circuit abnormality occurs in your product is at least double or greater than the rated current of the fuses. In addition, ensure that the abnormal current of your product does not exceed the maximum interrupting current of the fuses. 5. The fuses are designed to be used on the secondary side of a power supply. Do not use them on the primary side. 6. Ensure that the voltage applied to the fuses are within their rated voltage. 7. The fusing characteristics of the fuses are affected by the ambient temperature. Before use, mount the fuses on your products and carefully check and evaluate their category temperature range. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 06 Jan. 2019 Safety Precautions (Common precautions for Fuses) * When using our products, no matter what sort of equipment they might be used for, be sure to make a written agreement on the specifications with us in advance.
