1.1、 固體電解質鉭電容器

    A   固體電解質極性鉭電容器,一般不允許加反向電壓,并且不可在純交流電路中使用。若在不得已的情況下,允許在短時間內施加小量的反向電壓,其值為:25℃下:≤10%UR或1V(取小者);85℃下:≤5%UR或0.5V(取小者);125℃下:≤1%UR或0.1V(取小者)。

B   如果將電容器長期使用在有反向電壓的電路中時,請選用雙極性鉭電容器,但也只能在極性變換而頻率不太高的直流或脈動電路中使用。

1.3、 原則上禁止使用三用表電阻擋對有鉭電容器的電路或電容器本身進行不分極性的測試(容易施加反向電壓),當電路全部采用了35V以上(含有35V)固體鉭電容器時,應能承受三用表1.5V電源的反向測試,9V電源則應絕對禁止。

2.1、 直流偏壓與交流分壓峰值之和不得超過電容器的額定電壓值。

2.3、 紋波電流通過鉭電容器時產生了有功功率損耗,進而電容器自身溫升導致的熱擊穿失效概率增大,因此有必要對通過電容器的紋波電流或電容量允許的功率損耗進行限制(鉭電容器不應長期使用于交流分量大或純交流電路中)。 功率損耗(P有)與紋波電流(Irms)的關系由下式表 示: P有=V-·I漏+I2rms·R≈I2rms·Rs 其中:V-:直流偏壓(V);I漏:漏電流(A); Rs:等效串聯電阻(Ω);Irms:紋波電流。 由上式可以看出:當Rs增大或當Irms增大時,功率損耗增大。因此,在高頻線路中要求通過鉭電解電容器的紋波電流小和選用等效串聯電阻小的鉭電解 電容器。

2.3.1、各種固體電解質鉭電容器按殼號散熱效率所允許的功率損耗見表1。 表1 固體電解質鉭電容器允許的功率損耗及溫度降額系數

2.3.2、各種非固體鉭電容器按殼號允許最大紋波電流有效值(85℃,40KHz、0.66UR)見表2、表3。 表2:CA31、CA81型非固體電解質鉭電容器的最大紋波電流(有效值) 表3:CA35、CA351型非固體電解質鉭電容器的最大紋波電流(有效值)
