Product Description
Customized Signal Isolation Silicon Steel ZXY2622 Audio Transformer
This customized ZXY2622 audio isolation transformer features a high-performance silicon steel core and multifunctional impedance ratio design of 75Ω:75/300/600Ω. It provides efficient electrical isolation, balanced/unbalanced conversion, and precise impedance matching in signal transmission. The customized silicon steel material ensures high magnetic permeability and low loss characteristics, delivering flat frequency response and low distortion performance across the audio frequency band.
Key Functions
- Signal Electrical Isolation: Transmits signals through magnetic coupling, completely cutting off DC electrical paths between input and output terminals. Eliminates ground loop issues caused by potential differences between devices, effectively filtering out hum, buzzing, and common mode interference.
- Balanced/Unbalanced Conversion: Built-in natural 'Balun' function efficiently converts single-ended (unbalanced, 75Ω coaxial) signals into balanced (300Ω or 600Ω dual line) signals suitable for long-distance, anti-interference transmission, and vice versa.
- Multi-Impedance Matching: Unique tap design enables precise impedance matching for three professional scenarios:
- Isolation transmission: 75Ω to 75Ω for direct isolation
- Upgrade to standard balanced circuit: Convert 75Ω to standard 300Ω or 600Ω balanced input/output to ensure maximum signal power transmission and reduce reflection loss
Performance Characteristics
| Feature | Description |
|---|---|
| Core Feature & Impedance Ratio | 75Ω : 75Ω / 300Ω / 600Ω - A single component provides three standard impedance matching options: 1:1 isolation, 1:2 step-up (to 300Ω), and ~1:2.83 step-up (to 600Ω) |
| Core Material | Customized Silicon Steel Laminate offering high magnetic permeability and low core loss for excellent magnetic linearity and low distortion |
| Primary Function | Signal Isolation & Balun (Balance/Unbalance) - Galvanic isolation eliminates ground loop noise; inherent balun function converts between unbalanced and balanced lines |
| Key Performance | High Efficiency & Low Distortion - Optimized core and winding design ensures high power transfer efficiency and minimal harmonic distortion within the target audio band |
| Frequency Response | Optimized for Audio Band - Typically delivers flat frequency response tailored for voice/communication bands (300Hz - 3.4kHz) or wider audio ranges |
| Application | Versatile Interface Solution ideal for broadcast, professional audio, telecom, and measurement systems where impedance matching, isolation, and noise rejection are critical |
| Construction | Robust & Reliable design for professional/industrial use, typically featuring shielded case and solder lug or PCB pin terminations |
