Description
The Jantzen Cross Cap (low-value range) is a budget-friendly film capacitor designed for crossover networks where small capacitance values are required — particularly in high-pass filters for tweeters or trap notch filters.
Though entry-level, the Cross Cap delivers clear performance and stability far beyond electrolytic caps in terms of sound quality and lifespan.
🔧 Key Specs:
-
Capacitance Range: 0.10 – 1.80 µF
-
Tolerance: ±5%
-
Voltage Rating: 400 VDC
-
Dielectric: Metallized polypropylene foil
-
Type: Non-polarized, axial leads
-
Loss Factor (ESR): Moderate — better than electrolytics, higher than Z-Caps
🎧 Sound Characteristics:
-
Clearer and more accurate than budget bipolar electrolytics
-
Slightly soft top-end compared to higher-tier Z-Caps
-
Stable tone, decent transient handling, low distortion at this price point
✅ Recommended For:
-
Tweeter crossovers in budget or DIY 2-way speakers
-
Notch filters for resonance control
-
Replacement for small-value electrolytics in older speaker designs
PRODUCT FEATURE
The Cross Cap is offering a high-level of performance and quality at a very reasonable price point.
A great multipurpose entry-level audiophile capacitor.
A single foil (standard type MKP/PP foil) construction that uses a good quality aluminum and zinc based metalized polypropylene foil.
Available in a very wide range of capacitance values.
Virtually free of distortion and delivers a pleasant and rather neutral sonic profile.

⚖️ Compared to Higher-End Jantzen Models:
| Feature | Cross Cap (0.10–1.80 µF) | Superior Z-Cap | Silver Z-Cap |
|---|---|---|---|
| Sound Quality | Basic, clear enough | Open, detailed | Ultra-transparent, fast |
| Clarity & Depth | Acceptable | High | Exceptional |
| Price | $ | $$$ | $$$$ |
| Application | Budget tweeters/notches | High-end tweeters/mids | Reference-grade tweeter use |
💡 Bottom Line:
For cost-sensitive designs needing small capacitance values in high-frequency sections, the Cross Cap 0.10–1.80 µF offers a solid step up from electrolytics without the premium price of audiophile-grade caps.
