2-1.種類 T*e
不燃性塗裝型繞線有感電阻器以KNP表示之。
Wire Wound Resistor is called “KNP”
2-2.額定電力 Rated Wattage
額定電力(W)以數字表示,如1/2W、1W、2W、﹍﹍10W。
Shown by “W”﹑such as 1/2W 、1W、2W、﹍﹍10W。
2-3.端子形狀Terminal Form
視端子區分為P形、M形、F形。
Upon the shape of terminal, it has P Form and M form , F form
2-4.特性 Characteristic
溫度系數以“T”表示之,如:
Temperature Coefficient is its character represented by “T”, such as:
±350PPM/℃
2-5.公稱電阻值Nominal Resistance:
Ω,KΩ為單位,依據JIS-C6402為適用原則(E-24 Series)。
Ω,KΩ are its unit which is in accordance with JIS-C6402(E-24)series.
2-6.電阻值及容許誤差 Tolerance
在室溫中依檢測器測量,應在指定電阻值之容許誤差以內。
It is measured by Bridge-method at room temperature and expressed by a capital letter.
F ± 1% G ±2% J ±5% K ±10%

3,額定功率Rated power
額定電力是周圍溫度70℃以下可連續使用之負載電力*大值數,且應使機械性能與電氣性能滿
足。又周圍溫度*上記溫度時,依造圖一之電力輕減曲線而定。
Rated power is the value of Max load voltage specified at the ambient temperature of 70℃ and shall
meet the functions of electrical and mechanical performance. When the ambient temp.surp*es above
Mentioned temperature. The value declines as following
DERATING CURVE:
-30

3-1.額定電壓 Rated Voltage
依公式E=√PR求出連續使用額定電壓,如額定電壓*出*高使用電壓,
則以*高使用電壓為連續使用額定電壓
It is calculated as the following formula E=√PR
However, in case the voltage calculated exceeds the maximum load voltage, such the maximum load.
Voltage shall be regarded as its rated voltage, means whichever less.
E=連續使用額定電壓 E=Rated Continuous Working Voltage(V)
P=額定功率 P=Rated Power(W)
R=公稱電阻值 R=Nominal Resistance Value(Ω)
