Description
The Jantzen Audio Amber Z-Cap 630V is a premium
pure copper foil capacitor designed for high-end audio
applications requiring small capacitance values. Unlike Jantzen’s
metallized polypropylene capacitors, the Amber Z-Cap uses
solid copper foil electrodes, making it particularly
suitable for critical high-frequency signal paths.
The 0.010–0.47 µF / 630 VDC range is especially useful
for tweeter networks, bypass applications, impedance correction
and fine crossover tuning.
🔧 Specifications:
- Capacitance Range: 0.010 – 0.47 µF
- Tolerance: ±5%
- Voltage Rating: 630 VDC
- Conductor: Pure copper foil
- Type: Non-polarized audio capacitor
- Application: High-end loudspeaker crossovers
- Capacitance Range:
Optimized for small-value HF applications - Premium Construction:
Designed for critical audio signal paths
🎧 Sound Characteristics:
- Highly transparent and refined
- Excellent reproduction of fine high-frequency detail
- Natural tonal presentation
- Very good micro-detail and spatial information
- Particularly suited to high-resolution tweeter sections
Sound descriptions are subjective and depend strongly on the crossover
circuit, drivers and complete loudspeaker system.
✅ Recommended For:
- High-end tweeter crossover networks
- Super-tweeter circuits
- Bypass capacitor applications
- Notch and correction networks
- Fine-tuning high-frequency crossover response
- Premium DIY and reference-level loudspeaker projects

Bottom Line:
The Amber Z-Cap 0.010–0.47 µF / 630 VDC is a specialized
Jantzen capacitor for applications where
very small capacitance values and premium copper-foil
construction are required.
Compared with Cross Cap and
Standard Z-Cap, it is aimed at a much higher performance
level. Compared with Superior and
Silver Z-Cap, its main distinction is the
pure copper foil construction.
Compared with Alumen Z-Cap, Amber substitutes
copper foil for aluminum foil, while this particular
Amber series provides a substantially higher
630 VDC voltage rating.
For a high-end tweeter circuit, bypass position, super-tweeter,
or fine HF correction, the small-value Amber Z-Cap is one of
Jantzen Audio’s most specialized capacitor options.
