scope:

This standard applies to polar and bipolar tantalum electrolyte capacitors with solid and non-solid electrolyte for use in electronic equipment.

It comprises capacitors for long-life applications and capacitors for general-purpose applications. Capacitors for special purpose application may need additional requirements.

This standard covers three basic sub-families, namely:

Sub-family 1: Fixed non-solid electrolyte tantalum capacitors with foil electrode.

1A: Plain foil electrode.

1B: Etched foil electrode.

Sub-family 2: Fixed non-solid electrolyte tantalum capacitors with porous anode.

Sub-family 3: Fixed solid electrolyte tantalum capacitors with porous anode.

Object

The object of this standard is to prescribe preferred ratings and characteristics and to select from I E C Publication 384-1 (1982), the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted.
