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. Before using halogen-based or other high-activity fl ux, check the possible effects of the fl ux residues on the 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. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Oth er wise, the re sis tors'
6. Do not immerse the resistors in solvent for a long time. Before using solvent, carefully check the effects of immersion.
Design and specifi cations are each subject to change without notice. Ask factory for the current technical specifi cations before purchase and/or use.
