Please also refer to the common precautions for Fixed Resistors in this catalog. 1. 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 Metal(Oxide) Film Resistors (hereafter called the resistors) mounted on your product rathe r than only depending on the calculated powe r limit or steady-state conditions to complete the design or decide to use the resistors. 2. The resistors are covered with a special coating. Do not apply shock or vibration to them, or pinch them with long-nose pliers. Otherwise, the resistors may be damaged. 3. Do not apply excessive tension to the lead-connecte d sections. When bending the lead wire, do not apply excessive stress to the resistors and provide the wire with a natural curvature. 4. Do not brush the resistors during or after the cleaning process, which may be conducted after soldering. Otherwise, the coating film may be damaged. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
