A touching vinyl wire may cause damages to resistor element. Do not place vinyl wires around resist ors and be sure to consider where the resistors will be placed. Safety Precautions The following are precautions for individual products. Please also refer to the common precautions for Fixed Resistors shown on this catalog. 1. Transient voltage If there is a possibility that the transient phenomenon (signifi cantly 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 rath e r t h a n o n l y d e p e n d i n g on the calculated pow e r l i m i t or s t e a d y -s t a t e c on d i t i on s t o c om p l e t e t h e d e s i g n or d e c i d e t o u s e t h e r e s i s t or s . 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-connect ed 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 fi lm may be damaged. Aug. 201201
