    Higher relative humidifies are permitted at lower temperatures, e.g. 90 % at 20 ℃.

    4.4 安裝條件(Conditions of installation)

    a. 直接焊接在PCB上。熔斷器可垂直、水平或傾斜安裝。

    Weld the fuse on PCB directly. The fuse can be installed vertically, horizontally, or gradiently.

    b.工作場(chǎng)所如果存在顯著震動(dòng)和沖擊,請(qǐng)咨詢。

    If the fuse is likely to be exposed in service to abnormal vibrations or shocks, please consult  us.

    c.焊接溫度要求在260℃以下,否則有損壞熔斷電阻器的危險(xiǎn)。

    The temperature of jointing is below 260℃, otherwise, the fuse maybe be damaged.

    d.一般情況下取不大于90%額定電流較為適宜。

    It is convenient that the current is under 90% of the rated current.

    e.熔斷電阻器工作時(shí)不可觸摸,否則有人身傷害的危險(xiǎn)。

    Do not touch the fuse when it is in working condition.

    f.周圍無易燃易爆物體。

    There is no flammability all around.

    5.電壓規(guī)格(Voltage):

    額定電壓:250V AC /65V DC

    Rated Voltage:250V AC /65V DC

    注(Remarks):

    有效長(zhǎng)度會(huì)影響電流特性,絲狀熔斷電阻器有效長(zhǎng)度為16mm,則額定電流為標(biāo)稱值,有效長(zhǎng)度大于16mm,實(shí)際有效額定電流會(huì)變小,反之,實(shí)際額定電流變大。

    不建議有效尺寸小于12 mm情況下使用。

    The fuse rated current is the nominal value if efficient length is 16mm. The reality rated current should be altered if efficient length of the fuse is different from 16mm. The efficient length is beyond 16mm , the rated current is less than the nominal value .If it is less than 16mm, the rating current is greater than the nominal value.

    It is out of place that the efficient length is less than 12mm.
