Jantzen Premium ELKO Smooth Cap

Jantzen Premium ELKO Smooth Cap

The Premium ELKOs are made with a smooth foil to allow for less loss and to offer better performance and sound in audio applications.

They are small in size and offer good performance on crossovers, where sizing is an important factor.

These capacitors are especially excellent for the bass section of crossovers, due to their reasonable pricing in high capacitance values, compared to MKT or MKP capacitors.

These German made high-end bi-polar electrolytic capacitors, are made with a thin dielectric insulation (70 VDC) and have a tolerance of only 5% on capacitance values.

The thinner dielectric insulation makes for a capacitor with very low ESR/SEL and low dielectric absorption, making it a fast reacting audio grade capacitor.

Bi-polar electrolytic capacitors such as the Premium ELKOs, feature a secondary aluminium foil, providing sufficient AC voltage resistance, making them highly suitable for audio application.

Currently available in 3.3, 22, 33, 47, 56, 68, 82 an 100μF

They are not available between 3.3 and 22uF because Jantzen say that their range of Cross-Caps would be comparable in size and price.
