The following are precautions for individual products. Please also refer to the precautions common to Fixed Resistors
shown on page ER3 of this catalog.
1. Take measures against mechanical stress during and after mounting of Chip Attenuator (hereafter called the re sis tors)
2. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and eval u ate the op er a tions
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. 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'
7. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress.
Design and specifi cations are each subject to change without notice. Ask factory for the current technical specifi cations before purchase and/or use.
