jb Active and Passive Electronic Components

One key factor that differentiates types of electronic components is they are passive or active.

Active electronic components are those that can control the flow of electricity. For examples: transistor, vacuum tubes, silicon-controlled rectifiers (SCRs).
Passive electronic components are those that don’t have the ability to control electric current by means of another electrical signal. For examples: capacitors, resistors, inductors, transformers, and some diodes.

Jb is specialized in production of all kinds of capacitors, with 40 years production experience. It is our commitment to offer our customers the best quality products with fast delivery and the best after sales services.

jb Difference between Aluminum Electrolytic & Aluminum Polymer

Do you understand the difference between Aluminum Electrolytic and polymer electrolytic capacitors?

The biggest difference is that in polymer e-caps, a conductive polymer is used instead of a liquid electrolyte.
Aluminum electrolytic and aluminum polymer capacitors have very good behavior against bias effects of voltage and temperature. Furthermore, aluminum polymer capacitors have very good ageing characteristics. In comparison polymer e-caps offer significant advantages, especially their DC bias performance.

In order to make it easier for you to decide whicj type is better for you, below are the pros for these two types of capacitors:

Pros of Aluminum electrolytic capacitors:
-Higher voltage ratings available (jb Capacitors provide up to 600 Voltage)
-Better leakage current behavior

Pros of Polymer electrolytic capacitors:
-Lower ESR/higher allowable ripple current
-No dry-out behavior (As aluminum e-cap is with liquid electrolyte inside)
-Higher expected lifetime/loadlife

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.
