Wet Tantalum Capacitors with Hermetic Seal

Vishay STA represents a major breakthrough in Wet

Tantalum capacitor technology. Its unique cathode system,

also used in the ST, provides the highest capacitance per

unit volume available. The STA combines the inherent

reliability of wet tantalum with the capacitance stability of

solid tantalum, and there are no circuit impedance

restrictions. The range is exceptionally well suited for low

voltage filtering and energy storage applications.

FEATURES

• All tantalum, hermetically sealed case

• Terminations: axial leaded

• High and stable capacitance

• High reliability, rugged design

• 150 μF to 4700 μF

• -55 °C to +125 °C

APPLICATIONS NOTES

a) No continuous reverse voltage permissible.

b) Transient reverse voltage surges are acceptable under

the following conditions:

The peak reverse voltage does not exceed 1.5 V and the

peak current times the duration of the reverse transient

does not exceed 0.05 As. In addition, the repetition

frequency of the reverse voltage surge is less than 10 Hz.

c) The peak of the applied AC ripple and the applied DC

voltage must not exceed the DC voltage rating of the

capacitor.

d) Ripple current ratings by part number at 85 °C and

40 kHz are included in the table. Ripple current correction

factors for other temperatures and frequencies are given

on the next page.

Notes

• Material at egress is tantalum.

• Insulation sleeving will lap over the ends of the capacitor case.

• Tinned nickel leads, solderable and weldable.

• Approx. weight
