●
Recommended soldering conditions for reflow
· Reflow soldering shall be performed a maximum of
two times.
· Please contact us for additional information when
used in conditions other than those specified.
· Please measure the temperature of the terminals
and study every kind of solder and printed circuit
board for solderability before actual use.

<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 each electrode for 3 seconds or less.
● Never touch this product with the tip of a soldering iron.
Safety Precautions
The following are precautions for individual products. 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.
