■
In case of fl ow soldering, the land width must be small er than the Chip Resistor width to properly control the sol der amount
properly. Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In case of refl ow soldering,
solder amount can be adjusted, there fore the land width should be set to 1.0 to 1.3 times chip resistor width (W).

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 specifi ed derating curve.
2. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the operations
3. Do not use halogen-based or other high-activity fl ux. Otherwise, the residue may impair the resistors' per for mance
4. When soldering with a soldering iron, never touch the resistors' bodies with the tip of the soldering iron. When using a
5. As the amount of applied solder becomes larger, the mechanical stress applied to the resistors increases, causing
6. When the resistors' protective coatings are chipped, fl awed, or removed, the characteristics of the resistors may be
7. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the resistors'
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 im mer sion.
Design and specifi cations are each subject to change without notice. Ask factory for the current technical specifi cations before purchase and/or use.

of the resistors when installed in your products before use.
When applying pulses to the resistors, keep the pulse peak within the rated voltage.
