<Repair with hand soldering>
● Preheat with a blast of hot air or similar method. Use a soldering iron with a tip temperature of 350 °C or less. Solder
● Never touch this product with the tip of a soldering iron.
The following are precautions for individual products. Please also refer to the precautions common to EMI Filters,
Fuses, and Sensors(MR Elements) shown on page EX2 of this catalog.
1. Set the rated current so that the current passing through the Micro Chip Fuses (hereafter called the fuses)
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
4. The fuses are designed to be blown out by a current that is double or greater than the rated current. Ensure
5. The fuses are designed to be used on the secondary side of a power supply. Do not use them on the primary
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
Design and specifi cations are each subject to change without notice. Ask factory for the current technical specifi cations before purchase and/or use.
