Why You Should De-Rate Capacitors
Tantalum Capacitors. The tantalum capacitors is a special type of electrolytic capacitor. To make a tantalum capacitor, powdered tantalum is formed into a pellet through the sintering process. The pellet is submerged in an acidic solution and a DC voltage is applied, which creates an oxide layer over all the tantalum particles.

They provide higher capacitance in a smaller package than other types of capacitors, and they offer better voltage and temperature characteristics than high-capacitance ceramic capacitors. Setting example of measurement conditions ... Fixed tantalum capacitors with non-solid electrolyte and foil electrode(IEC 60384-15)(JIS C5101-15)
Tantalum Capacitor vs Ceramic
By not being polarized, ceramic capacitors have a better frequency response. Temperature Response: When subjected to changes in temperature, tantalum capacitors usually show linear capacitance change while ceramic capacitors usually have a non-linear response. However, ceramic capacitors can be made to trend linearly by …

The Basics & Benefits of Tantalum & Ceramic Capacitors
Tantalum Capacitors . Tantalum capacitors achieve high capacitance values through a combination of factors, including a tantalum pentoxide (Ta 2 O 5, εr = 27) dielectric, a large plate area (A), and a very thin dielectric thickness (d). The positively charged dielectric plate of a tantalum capacitor is formed from pure elemental grade …
bypass capacitor
I require a 3.3uf capacitor in a 30 VDC environment for three different purposes: decoupling of precision ADC or DAC; input to a regulator (linear, switching, LDO); and; output of any regulator for the purpose of ripple reduction. I can either use an MLCC (Multi-Layer Ceramic Capacitors) or Tantalum capacitor.
The engineer''s guide to tantalum electrolytic capacitors
Tantalum capacitors have thin dielectric layers that result in higher capacitance per unit of volume when compared to aluminum electrolytic capacitors. …
component selection
From the perspective of an electronics designer, but also taking into account price/cost and social considerations (see Coltan mining and ethics link below), I tend to avoid Tantalum capacitors under many circumstances, while favouring Multi-Layer Ceramic Capacitors (MLCCs). My question, bluntly stated is: In which specific cases …
