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 NO_X.

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.

Surface Mount Resistors

Safety Precautions (Common precautions for Surface Mount Resistors)

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

Resistors in this catalog.

1. Take measures against mechanical stress during and after mounting of Surface Mount Resistors

(hereafter called the resistors) so as not to damage their electrodes and protective coatings.

Be careful not to misplace the resistors on the land patterns. Otherwise, solder bridging may occur.

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

Some circuit boards, wiring patterns, temperatures of heat generated by adjacent components, or

ambient temper a tures can become factors in the rise of the temperature of the resistors, regardless of

the level of power applied. Therefore, check the conditions before use and op timize them so as not to

damage the boards and peripheral components.

Make sure to contact us before using the resistors under special conditions.

3. 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. Never exceed the rated power.

Otherwise, the performance and/or reliability of the resistors may be impaired.

4. Transient voltage

If there is a possibility that the transient phenomenon (significantly high voltage applied in a short time)

may occur or that a high voltage pulse may be applied, make sure to evaluate and check the

characteristics of resistors mounted on your product rather than only depending on the calculated power

limit or steady-state conditions.

5. If the resistors are to be used in high frequency circuits, carefully check the operation before use.

Such circuits change the electrical characteristics of the resistors.

Before using halogen-based or other high-activity flux, check the possible effects of the flux residues on the

6.

performance and reliability of the resistors.

7. 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.).

8. Mounting of the resistors with excessive or insufficient wetting amount of solder may affect the

connection reliability or the performance of the resistors. Carefully check the effects and apply a proper

amount of solder for use.

9. 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.

10. 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.

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

12. Do not immerse the resistors in solvent for a long time.

Before using solvent, carefully check the effects of immersion.

13. Do not apply excessive tension to the terminals.
