Hot-spot Temperature (for Reference)

The temperature of the resistor body increases with the curve below. A touching vinyl wire may cause damages

to resistor element. Do not place vinyl wires around resistors 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 (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 rather than only depending

on the calculated power 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-connected 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.
