Product Description

ZXY DU19 Permalloy Signal Isolation Transformer

The ZXY DU19 is a high-fidelity permalloy signal isolation transformer designed for professional analog audio equipment. Featuring a high-permeability permalloy core and oxygen-free pure copper winding with 1:1+1+1 multi-winding structure, it delivers ultra-wide flat frequency response, low signal distortion, and excellent electrical isolation. This transformer effectively eliminates ground-loop hum, common-mode noise, and crosstalk while preserving original audio signal integrity. As a direct manufacturer, we support custom winding ratios, pin-out configurations, and encapsulation for your audio hardware projects.

Key Features

Premium permalloy nickel-iron core with high permeability and low hysteresis loss for minimal audio distortion
1:1+1+1 multi-winding configuration for flexible balanced-unbalanced conversion and multi-channel signal isolation
Wide flat frequency response maintains natural sound performance across the full audio band
Superior ground-loop noise suppression eliminates hum and buzz in audio signal chains
Oxygen-free pure copper winding ensures stable signal transmission with low insertion loss
PCB through-hole mounting with compact DU19 form factor for easy audio device integration
RoHS & CE compliant with industrial insulation grade
OEM customization support for turns ratio, pin assignment, and insulation requirements
Factory direct supply with standard MOQ 1000pcs; samples available for validation
