Product Details
Standard 600Ω:600Ω impedance matching
Professional 1:1 coupling transformer designed for balanced line-level audio signals, microphone preamplifiers, and audio interface isolation applications.
High-performance permalloy core
Utilizes ultra-high-permeability permalloy core material for extended low-frequency response, extremely low core losses, and ultra-low total harmonic distortion (THD), ensuring pristine sound fidelity.
Electrical isolation and noise suppression
Effectively breaks ground loops and suppresses common-mode noise, eliminating the 50/60 Hz AC hum and radio frequency interference commonly found in professional audio chains.
Microphonics-resistant mechanical design
Fitted with soft rubber mounting feet to absorb physical vibration, preventing mechanical noise from coupling into the audio signal — ideal for high-gain preamplifier stages.
Compact EI28 PCB mounting
Standard 2+2 soft-wire DIP through-hole layout for secure, space-saving PCB integration, suitable for both prototyping and volume production.
High-temperature insulation and durability
Wound with heat-resistant yellow insulation tape and encapsulated in a rigid bobbin structure, ensuring excellent dielectric strength, thermal stability, and long-term reliability.
RoHS, REACH, and CE compliant
Manufactured with environmentally safe materials and fully certified to international regulatory standards, facilitating global customs clearance and distribution.

FAQ
1. What is the ZXY-EI28 600:600 audio isolation transformer used for?
Answer: This transformer is specifically designed for professional audio applications requiring electrical isolation, ground loop elimination, and impedance matching. It is commonly used in microphone preamplifiers, broadcast mixing consoles, DI boxes, audio interfaces, and high-fidelity audio systems to ensure clean, noise-free signal transmission while protecting downstream equipment from DC bias and voltage surges.
2. What does the "600Ω:600Ω" impedance ratio mean?
Answer: This is a 1:1 coupling transformer designed for line-level audio signals and telecommunications interfaces. The 600Ω rating indicates that the transformer is designed to be driven by and loaded with 600Ω circuits for optimal frequency response. This matches the standard impedance of professional balanced audio lines, allowing the transformer to transmit audio signals with minimal signal alteration while providing isolation.
3. What makes the permalloy core material special for audio applications?
Answer: Permalloy is a nickel-iron alloy with extremely high magnetic permeability, offering several advantages for audio transformers: superior low-frequency response with higher primary inductance; extremely low core losses and very low distortion; excellent low-level signal performance with extended frequency response. Compared to silicon steel cores, permalloy delivers cleaner, more transparent sound, particularly in critical audio paths where signal purity is paramount.
