Capacitor Basics. The basic formula for capacitance is C = εr * ε0 * (A/d), in which. · C = capacitance, in Farads (F) · A = the area of overlap between the two plates in square meters (m2) · εr = relative static permittivity or the dielectric constant. · ε0 = the electric constant (ε0 ≈ 8.854×10−12F/m) · d = the separation

Tantalum capacitors are innately polarized capacitors with positive and negative lead and are appropriate with DC supplies. The polarity and markings on the capacitors make it easy to identify the anode and cathode. Two bands and a positive sign helps in identifying the value of capacitance and maximum working voltage.

THE BASICS OF TANTALUM CAPACITOR TECHNOLOGY. Most metals form crystalline oxides which are non-protecting, such as rust on iron or black oxide on copper. A few metals form dense, stable, tightly adhering, electrically insulating oxides. These are the so-called valve metals and include titanium, zirconium, niobium, tantalum, hafnium, and aluminum.
