Cautions for Safety
The following are precautions for individual products. Please also refer to the precautions common to Fixed Resistors shown on page ER3 of this catalog.
1. Checking the fusing conditions
1) Fusing characteristics differ depending on the type, shape, and resistance. Check the fusing conditions
before selecting the type of Metal (Oxide) Film Fusing Resistors (hereafter called the Fusing Resistors) to be
used.
2) Use the Fusing Resistors under the maximum open circuit voltage. Otherwise, arcing may occur when a voltage
much higher than the rated one is applied in the event of an abnormality in the circuit, or when a high voltage
is applied after fusing.
2. Checking for pulse voltage, impact voltage, and transient voltage
Make sure to evaluate and check the Fusing Resistors mounted on your product if they are to be mounted on
a circuit that generates an impact voltage, or if there is a possibility that the transient phenomenon
(significantly high voltage applied in a short time) may occur or that a pulse voltage with a high peak voltage
may be applied. Make sure to consult our sales staff before using the Fusing Resistors under special conditions.
3. Conditions of use in a steady state
Make sure that the load conditions have a sufficient allowance for the power derating curve. The characteristics
of the Fusing Resistors are set by using a constant voltage circuit.

Caution for Safety
(Common precautions for Fixed Resistors)
¥ 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.
¥ 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
(1) Precautions for use
¥ These products are designed and manufactured for general purpose and standard use in general electronic
equip ment (e.g. AV equipment, home electric appliances, office equipment, information and communication
equipment)
¥ 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 NO2
4. In an environment where strong static electricity or electromagnetic waves exist
5. In an environment where these products cause dew condensation
6. 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
perfor mance 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.
(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 %.
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 NO2
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.
