Applicable Scope: This KNP t*e standard specification is for use in consumer electronics

computer, telecommunication equipments﹍﹍etc

2.形名　　Part Number

　依據其種類、額定電力、端子型狀、特性、公稱電阻及容許誤差等分別注明。

　It is composed by T*e, Rated Wattage, Terminal Form, Characteristic, and Nominal Resistance

  and Tolerance.e.g.

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%

2-7.使用合金线

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:

     圖1: 負載減輕曲線

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)

3-2備注

1.  K N P阻*範圍0.01Ω-1KΩ(N K N P則為0.01Ω-100Ω).

2.  無感繞線電阻(N K N P)的特性說明:

本項產品可減少各种電子回路的雜訊或瞬間*,如用在交換式電源供應器或不斷電設備之電

*應器(Current Sensory)或*吸收部分(Snubbed)時, 可將雜訊干擾降至限度,*振頻率或縮小前產品的體積,節省材料費用,並可*振蕩,且*降低自然可減少電磁波之干擾。
