Surface Mount Resistors Safety precautions

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

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

performance and reliability of the resistors.

5. 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.).

6. 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 amounts of solder.

7. 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.

8. 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.

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

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

11. 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

Fixed Metal (Oxide) Film Resistors mounted on your product rather than only depending on the calculated

power limit or steady-state conditions to complete the design or decide to use the resistors.

12. Do not apply excessive tension to the terminals.

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.
