PTH零件識別(PTH Components Distinguish)

    一 電阻(Resistor)

    PTH電阻之色碼代表意義如下:

    The meaning of color bar in PTH resistor is as below:

    (1)一般電阻:其阻值以4條色碼表示, 前2碼表示底數(shù), 第3碼為乘數(shù), 第4碼為此電阻之最大誤差值,。 Ordinary resistor: Using 4 color bars to represent resistor value, the first 2 bars refer to base, the 3rd bar is times, the 4th bar is error value.

    其阻值為: 10*105 = 1000000 ohm = 1M ohm, 誤差值為±5% = ±50K ohm

    The resistor value is: 10*105 = 1000000 ohm = 1M ohm, Error is ±5% = ±50K ohm.

    其阻值為: 60*100 = 60 ohm, 誤差值為±10% = ±6 ohm

    The resistor value is: 60*100 = 60 ohm, Error is ±10% = ±6 ohm. (

    2) 精密電阻:其阻值以5條色碼表示, 前3碼表示底數(shù), 第4碼為乘數(shù), 第5碼為此電阻之最大誤差值,。 Precise resistor: Using 5 color bars to represent resistor value, the first 3 bars refer to base, the 4th bar is times, the 5th bar is error value.

    其阻值為: 100*104 = 1000000 ohm = 1M ohm, 誤差值為±1% = ±10K ohm.

    The resistor value is: 100*104 = 1000000 ohm = 1M ohm, Error is ±1% = ±10 K ohm.

    其阻值為: 620*102 = 62000 ohm = 62K ohm, 誤差值為±1% = ±620 ohm.

    The resistor value is: 620*102 = 62000 ohm = 62K ohm, Error is ±1% = ±620 ohm.

    (3) 0 奧姆電阻, 其色碼之標示為:
