Safety Precautions

The following are precautions for individual products. Please also refer to the precautions common to Fixed Resistors

shown on page ER2 of this catalog.

1. Keep the rated power and ambient temperature within the speciﬁed derating curve.

* When positioning and mounting Metal Film Thermosensitive Chip Resistors (hereafter called the resistors), make

allowance for the effect of heat generated through close contact between the resistors and neighboring components

and for the temperature rise of adjacent heat-generating components.

2. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the operations

of the resistors when installed in your products before use.

When applying pulses to the resistors, keep the pulse peak within the rated voltage.

3. Do not use halogen-based or other high-activity ﬂux. Otherwise, the residue may impair the resistors' performance

and/or reliability.

4. When soldering with a soldering iron, never touch the resistors' bodies with the tip of the soldering iron. When using a

soldering iron with a high temperature tip, ﬁnish soldering as quickly as possible (within three seconds at 350 °C max.).

5. As the amount of applied solder becomes larger, the mechanical stress applied to the resistors increases, causing

problems such as cracks and faulty characteristics. Avoid applying an excessive amount of solder.

6. When the resistors' protective coatings are chipped, ﬂawed, or removed, the characteristics of the resistors may be

impaired. Take special care not to apply mechanical shock during automatic mounting or cause damage during

handling of the boards with the resistors mounted.

7. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the resistors'

protective coatings and bodies may be chipped, affecting their performance.

8. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress.

9. Do not immerse the resistors in solvent for a long time. Before using solvent, carefully check the effects of immersion.

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.

Safety Precautions (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 and standard use in general electronic equipment

(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 Cl

, H

S, NH

, SO

, or NO

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 Environment

Avoid any environment where strong electromagnetic waves 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.

(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 Cl

, H

S, NH

, SO

, or NO

2. In direct sunlight

Package markings include the product number, quantity, and country of origin.

In principle, the country of origin should be indicated in English.
