本规范涵盖了固定、电解（固体电解质）、钽、模制、保形涂层和金属外壳的一般要求，带有塑料端部填充非气密密封电容器，主要用于滤波器、旁路、耦合和交流（ac）组件比直流（dc）额定电压小的其他应用。这些电容器仅用于提供补充防潮保护的场合，或不需要密封防潮保护的非关键应用场合。

This specification covers the general requirements for fixed, electrolytic (solid electrolyte), tantalum, molded, conformal coated and metal cased with plastic end-fill nonhermetically sealed capacitors, primarily intended for filter, bypass, coupling, and other applications where the alternating current (ac) component is small compared to the direct current (dc) rated voltage. These capacitors are intended to be used only where supplemental moisture protection is provided or for noncritical applications where hermetic moisture protection is not required.
