10μF 30 VDC-rated tantalum capacitors, solid electrolyte epoxy-dipped style.A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits. It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode. Because of its very thin and relatively high permittivity dielectric layer, the tantalum capacitor distinguishes itself from other conventional and electrolytic capacitors in having high capacitance per volume (high volumetric efficiency) and lower weight.

Tantalum is a conflict mineral. Tantalum electrolytic capacitors are considerably more expensive than comparable aluminum electrolytic capacitors.

Tantalum capacitors are inherently polarized components. Reverse voltage can destroy the capacitor. Non-polar or bipolar tantalum capacitors are made by effectively connecting two polarized capacitors in series, with the anodes oriented in opposite directions.

Selection Guide

When selecting tantalum electrolytic components, use the following guide based on the jb Tantalum Capacitors in Different Styles: Axial, Radial and SMD-chip Versions (Size Comparison with a Match):

  • Specifications & Styles: Available in 10 $\mu F$ 30 VDC-rated versions, solid electrolyte epoxy-dipped style, offered in different styles including axial, radial, and SMD-chip versions.

  • Structural Properties: Consists of a porous tantalum metal pellet anode covered by an insulating oxide dielectric layer, surrounded by a liquid or solid electrolyte cathode.

  • Polarity Guidelines: Inherently polarized components. Non-polar or bipolar options can be created by connecting two polarized capacitors in series with opposing anodes.

Frequently Asked Question (FAQ)

  • Q: What styles are available for jb Tantalum Capacitors? A: They are available in different styles, including axial, radial, and SMD-chip versions, as featured on the jb Tantalum Capacitors page.

  • Q: What makes tantalum capacitors different from conventional electrolytic capacitors? A: They have a very thin and relatively high permittivity dielectric layer, giving them high capacitance per volume (high volumetric efficiency) and lower weight.

  • Q: Can tantalum capacitors handle reverse voltage? A: No, tantalum capacitors are inherently polarized components, and reverse voltage can destroy the capacitor. Non-polar or bipolar versions are made by connecting two polarized capacitors in series with opposite anode orientations.
