Consider to use within the sufficient allowance under the power derating curve. 2. Confirm if overload condition at abnormal usage is within the fusing sphere. 3. In case of application of pulse waveform voltage, confirm if it is within the limit of the fuse type resistor. 4. Confirm the cautions described in each fuse type resistor. As we produce fuse type resistors of different rated powers, appearances and resistance ranges, select them for the purpose of your use. If you use fuse type resistor in special conditions or do not understand to select it, ask us before use. 00 Sep. 2010 – 67 –
