Technical Paper: Determining Ripple Current Capability In Tantalum Hybrid Capacitors

Because of its high specific power, the tantalum Hybrid capacitor fits where other capacitors do not, but its small size is sometimes a disadvantage with respect to heat dissipation. Electrolytic capacitors with similar electrical characteristics compared to Hybrid capacitors have several times the physical size and therefore have much larger surface areas from which to radiate heat. This paper evaluates the relationship between ripple current and temperature rise in tantalum Hybrid capacitors.
