溫度變化將引起電解電容的到介質(zhì)損耗變化，從而影響其使用壽命。溫度每升高10℃時，電解電容器的壽命就降低50％，同時還引起阻容時間常數(shù)變化，甚至發(fā)生因介質(zhì)損耗過大而熱擊穿的情況。

　　The change of temperature will cause the change of dielectric loss of electrolytic capacitor, which will affect its service life. When the temperature increases by 10 ℃, the life of the electrolytic capacitor decreases by 50%. At the same time, the time constant of resistance and capacitance changes, and even thermal breakdown occurs due to excessive dielectric loss.

　　此外，溫度升高也將使電感線圈、變壓器、扼流圈等的絕緣性能下降。

　　In addition, the insulation performance of inductor coil, transformer and choke coil will decrease with the increase of temperature.

　　濕度導(dǎo)致失效：

　　Failure due to humidity:

　　濕度過高，當(dāng)含有酸堿性的灰塵落到電路板上時，將腐蝕元器件的焊點與接線處，造成焊點脫落，接頭斷裂。

　　When the humidity is too high, when the dust containing acid and alkali falls on the circuit board, it will corrode the solder joints and wiring of the components, causing the solder joints to fall off and the joints to break.

　　濕度過高也是引起漏電耦合的主要原因。

　　High humidity is also the main cause of leakage coupling.

　　而濕度過低又容易產(chǎn)生靜電，所以環(huán)境的濕度應(yīng)控制在合理的水平。

　　And the humidity is too low and easy to produce static electricity, so the humidity of the environment should be controlled at a reasonable level.

　　過高電壓導(dǎo)致器件失效：

　　High voltage leads to device failure

　　施加在元器件上的電壓穩(wěn)定性是保證元器件正常工作的重要條件。過高的電壓會增加元器件的熱損耗，甚至造成電擊穿。對于電容器而言，其失效率正比于電容電壓的5次冪。對于集成電路而言，超過其最大允許電壓值的電壓將造成器件的直接損壞。

　　The voltage stability applied to components is an important condition to ensure the normal operation of components. Too high voltage will increase the thermal loss of components, and even cause electrical breakdown. For capacitors, the failure rate is proportional to the fifth power of capacitor voltage. For integrated circuits, the voltage exceeding the maximum allowable voltage will cause direct damage to the device.

　　機(jī)械振動與沖擊會使電解電容一些內(nèi)部有缺陷的元件加速失效，造成災(zāi)難性故障，機(jī)械振動還會使焊點、壓線點發(fā)生松動，導(dǎo)致接觸不良；若振動導(dǎo)致導(dǎo)線不應(yīng)有的碰連，會產(chǎn)生一些意象不到的后果。

　　Mechanical vibration and impact will accelerate the failure of some internal defective components of electrolytic capacitor, resulting in catastrophic failure. Mechanical vibration will also make solder joints and wire pressing points loose, resulting in poor contact; if the vibration leads to improper contact of wires, it will produce some consequences that cannot be imagined.

　　所以，電解電容在適宜的溫度范圍內(nèi)以及良好的工作環(huán)境中才能發(fā)揮做大的功效，避免因外界因素的干擾導(dǎo)致電容失效，導(dǎo)致整體電路故障。

　　Therefore, the electrolytic capacitor in the appropriate temperature range and good working environment can play a bigger role, avoid the interference of external factors lead to capacitor failure, resulting in the overall circuit failure.
