jb Tantalum Capacitors in Different Styles: Axial, Radial and SMD-chip Versions (Size Comparison with a Match)

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.

jb Team Wish You Happy Chinese New Year

jb team would like to wish you a happy new year and share the happiness from our culture with you.
Do you know there is no set date for Chinese New Year, Spring Festival is based on lunar calendar and we have 12 kinds animals in a round to represent every year?
This year is year of pig and it also is the last animals of 12.

We would like to inform you that we will have about 10 days holidays for our Spring festival from the beginning of February. 
But the great sales team will only take days off from Feb. 5th to 7th, if you have any inquiry or request during Spring Festival, please feel free to contact us anytime you need.  We will provide the best service for you as usual.

Small tip for new order at the beginning of this year:
If you have any order plan for next 2 months, please place order with your sales with in these two weeks ( Jan. 28th to Feb. 8th).
