Rockford Fosgate - 2 Farad Hybrid Digital Capacitor

RFC2D
2 Farad Hybrid Digital Capacitor

Low ESR (Equivilent Series Resistance), combination carbon capacitor/electrolytic

capacitor, platinum plated. (2) 1/0 AWG/4AWG power inputs and (2) 1/0 AWG/4 AWG

ground inputs/platinum plated. Digital volt meter (blue).

Improves sound quality - cleaner mids and highs

Louder and harder hitting bass

Platinum plated

Short Description:
Hybrid carbon capacitor/electrolytic capacitor combines best of both

technologies into single design.

Acronym:
Equivalent Series Resistance

Short Description:
Maintains low internal resistance and retains rated capacitance value.

Long Description:
Electrolytic capacitors suffer "aging" effects when compared to all other electronic parts.

Electrolytic capacitors age in several ways: They can become electrically leaky, causing

a DC current through them that can make them blow up. They can shift in capacitance

value. But the most common way they degrade is by a steady increase in their equivalent

series resistance. This is the undesired internal resistance that appears in series

with the wanted capacitance at a given frequency.

The ESR of an electrolytic capacitor is normally just a small fraction of an Ohm for a

high capacitance, low voltage capacitor (such as a 1000µF, 16V cap.) When the capacitor

ages, this resistance increases, and it can completely cease to functio. It's very common

to find capacitors that have degraded to 100 times their normal resistance, while their

capacitance remains fine!

Rockford Fosgate capacitors are low ESR, resulting in long lasting, high performance energy storage.
