The rated ambient temperature refers to the temperature around the resistor mounted inside the equipment, not to the air temperature outside the equipment。 5-3.額定功率：在 70℃環境溫度下進行耐久性試驗，而且阻值變化不超過該試驗的允許值時所允許的最大功率。 Rated power：At 70 ℃ ambient temperature durability test, and the change in resistance does not exceed the value of the test allows the maximum power allowed。 5-4.降功率曲線：額定功率系適應在周圍溫度 70℃可以連續負載的最大功率,但額定環境溫度如超過 70℃時之額定 電力則依圖的降功率曲線實施。 Rated power is maximum power which can be continuously loaded at specified ambient temperature 70 ℃, however when Rated Ambient Temperature exceeds 70℃,rated power should be determined form the derating curve。 5-5.額定電壓：額定環境溫度或端子部溫度下可連續施加的最大直流電壓或交流電壓（商用頻率實效值），用額 定功率和公稱電阻值，按以下公式計算。但額定電壓不可超過最大工作電壓。 Rated Voltage：Maximum allowable D.C. or A.C. voltage(rms), capable to be continuously applied to a resistor or a resistor element under the rated ambient temperature or terminal part temperature. It shall be calculated from the rated power and nominal resistance using the following formula. The rated voltage shall not exceed the max. working voltage。 U：電壓 I：電流 P：功率 R：阻值 5-6. 臨界阻值：在不超過最高使用電壓的情況下可施加額定功率的最大公稱電阻值。在臨界電阻值下，額定電壓 等於最大工作電壓。 Critical Resistance：The maximum nominal resistance value at which the rated power can be applied without exceeding the maximum working voltage. The rated voltage is equal to the max. working voltage at the critical resistance value。 5-7.最高使用電壓：電阻器或電阻元件上可連續施加的最大直流電壓或交流電壓（商用頻率實效值）。但在臨界電 阻值以下，可以施加的最大電壓為額定電壓。 Maximum Working Voltage：Maximum D.C. or A.C. voltage(rms) that can be continuously applied to the terminations of a resistor. However, the maximum value of the applicable voltage is the rated voltage at the critical resistance value or lower。 5-8.過負荷電壓：在短時間過載試驗中可連續施加5秒鐘的電壓，一般為額定電壓的2.5倍，但不可超過最大過載電壓。 Allowable voltage：which is applied in 5 sec. under short time overload test. Overload voltage shall be 2.5 times of rated voltage or max. overload voltage, whichever is lower。 3 CARBON FILM FIXED RESISTOR 碳膜固定電阻器 6. 尺寸 Dimension Unit: mm Size L±1 D±1 H±3 d±0.06 Resistance range 1/6W 1/8W 1/4WS 3.5* 1.7* 27 0.45 0Ω& 0.1Ω~15MΩ 1/4W 1/2WS 6.5* 2.4* 27 0.50 0Ω& 0.1Ω~22MΩ 1/2W 1WS 9.2 3.3 26 0.60 0Ω& 0.1Ω~22MΩ 1W 2WS 11 4.5 28 0.70 0.1Ω~22MΩ 2W 3WS 15 5.0 32 0.78 0.1Ω~22MΩ 3W 5WS 18 6.0 33 0.78 0.1Ω~22MΩ Type Tolerance ±5% ±2% 注：①0Ω阻值範圍為
