Jantzen Audio Silver Z-Cap MKP 0,10 – 22,00 µF +/- 2% 800 – 1200 VDC Metalized Polypropylene Foil Super-capacitor

Description

The Silver Z-Cap MKP line from Jantzen Audio is a premium series of metallized polypropylene foil capacitors, engineered for high-performance audio crossover networks. These capacitors deliver exceptional sonic clarity, low ESR, and minimal dielectric absorption, making them ideal for high-end loudspeaker applications.

Key Features:

• Capacitance Range: 0.10 µF to 22.00 µF

• Tolerance: ±2% for precise frequency response

• Voltage Rating: 800 VDC (standard) / 1200 VDC (selected values)

• Construction: Metallized polypropylene foil for long-term stability and low losses

• Terminals: Tinned, solid wire leads for secure soldering

• Applications: High-end speaker crossovers, especially in tweeter and midrange paths

• Performance: Transparent, open sound with fast transient response

Why It Matters:
The Silver Z-Cap MKP is designed for audiophiles who demand exacting quality. With its tight tolerance and high-voltage capability, it ensures detail and consistency in signal handling, even at dynamic peaks.

PRODUCT FEATURE
Where the Superior Z-Cap is made with pure copper lead-wires, the Silver Z-Cap is made with pure silver lead-wires, changing the sound characteristics of the capacitor slightly.
Highly recommended for tweeters and mid-range application for high-end passive speakers and as coupling capacitors in tube and power amplifiers.
The Silver Z-Cap is a metalized polypropylene foil capacitor but made as special construction we call a “Super MPK Capacitor”.
Super MKP capacitors are made with a double lane of metalized polypropylene foil, hence a double foil construction.
By using special winding machines and winding techniques, two capacitors are connected in series within one capacitor housing,
When making this type of capacitor you therefore need 4 times the foil used in standard type metalized polypropylene foil capacitors.
Compared to standard type metalized polypropylene foil capacitors, the Superior Z-Cap is on a higher audiophile level, where even finest nuance improvements can be heard.
An extremely well made and precise MKP capacitor with a tolerance on capacitance of only +/- 2%.
We do not fill our capacitors with any dielectric fluid, which eliminates all risks of evaporation or leakage that can shorten longevity and quality of the capacitor.
