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.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
Recommended Soldering Conditions
Recommendations and precautions are described below.
* 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 neigh bor ing components
and for the temperature rise of adjacent heat-generating components.

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