Application Guidelines
Precautions on the whole
• 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. The design and specifications in this catalog are subject to change without
prior notice.
• Do not use the products beyond the specifications described in this catalog.
• This catalog explains the quality and performance of the products as individual components. Before use, check and evaluate
their operations when installed in your products under the actual conditions for use.
• Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment where a
defect in these products may cause the loss of human life or other significant damage, such as damage to vehicles
(automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating appliances,
combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
✽ Systems equipped with a protection circuit and a protection device.
✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault.
✽ Systems equipped with an arresting the spread of fire or preventing glitch.
1. Precautions for use
• These products are designed and manufactured for general and standard use in general elec tron ic equipment.
(e.g. AV equipment, home electric appliances, office equipment, information and communication equipment)
For applications in which special quality and reliability are required, or if the failure or malfunction of the
products may directly jeopardize life or cause threat of personal injury (such as for aircraft and aerospace
equipment, traffic and transport equipment, combustion equipment, medical equipment, accident prevention
and anti-theft devices, and safety equipment), please be sure to consult with our sales representative in
advance and to exchange product specifications which conform to such applications.
• These products are not intended for use in the following special conditions. Before using the products, carefully
check the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent.
2. In direct sunlight, outdoors, or in dust.
3. In salty air or air with a high concentration of corrosive gas, such as Cl2,H2S,NH3,SO2,or NOX .
4. Electric Static Discharge (ESD) Environment.
These components are sensitive to static electricity and can be damaged under static shock (ESD).
Please take measures to avoid any of these environments.
Smaller components are more sensitive to ESD environment.
5. Electromagnetic and Radioactive Environment.
Avoid any environment where strong electromagnetic waves and radiation exist.
6. In an environment where these products cause dew condensation.
7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with
resin or other materials.
• These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.
• Carefully position these products so that their temperatures will not exceed the category temperature range due to
the effects of neighboring heat-generating components. Do not mount or place heat-generating components or
inflammables, such as vinyl-coated wires, near these products.
• Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the performance
or reliability of the products.
• Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the performance or
reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water residues.
Otherwise, the insulation performance may be deteriorated.
• Do not apply flux to these products after soldering. The activity of flux may be a cause of failures in these
products.
• Refer to the recommended soldering conditions and set the soldering condition. High peak temperature or long
heating time may impair the performance or the reliability of these products.
• Recommended soldering condition is for the guideline for ensuring the basic characteristics of the products,
not for the stable soldering conditions. Conditions for proper soldering should be set up according to individual
conditions.
1-Oct-19
Fuses
• Do not reuse any products after removal from mounting boards.
• Do not drop these products. If these products are dropped, do not use them. Such products may have received
mechanical or electrical damage.
• If any doubt or concern to the safety on these products arise, make sure to inform us immediately and conduct
technical examinations at your side.
2. Precautions for storage
The performance of these products, including the solderability, is guaranteed for a year from the date of arrival
at your company, provided that they remain packed as they were when delivered and stored at a temperature
of 5 °C to 35 °C and a relative humidity of 45 % to 85 %.
The performance of Thermal Cutoffs is guaranteed for a year after our delivery, provided that they are stored
at a temperature of -10 °C to +40 °C and a relative humidity of 30 % to 75 %.
Even within the above guarantee periods, do not store these products in the following conditions.
Otherwise, their electrical performance and/or solderability may be deteriorated, and the packaging materials
(e.g. taping materials) may be deformed or deteriorated, resulting in mounting failures.
1. In salty air or in air with a high concentration of corrosive gas, such as Cl2,H2S,NH3,SO2,or NOX .
2. In direct sunlight.
<Package markings>
Package markings include the product number, quantity, and country of origin.
In principle, the country of origin should be indicated in English.
3. Precaution specific to this product
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.
