EI19 Core 170V Rated Voltage Horizontal Mount Audio Isolation Transformer for Low Frequency Applications

EI19 170V Horizontal Low Frequency Audio Isolation Transformer. This horizontal mount EI19 audio transformer is built for audio signal isolation and impedance matching at 170V rating. It breaks ground loop hum, protects audio circuits and maintains clean sound quality for speaker modules, audio amplifiers, intercom systems and consumer audio devices.

It is a drop-in replacement for famous audio transformer brands like Triad, Signal Transformer and Bourns, with equal or better audio performance. It fits standard PCB footprint for horizontal through-hole mounting. OEM custom winding and parameter tuning are available.

• Matches or outperforms Triad, Signal Transformer, Bourns equivalent EI19 audio transformers, fully pin-to-pin compatible for direct replacement
• Ultra-low distortion and flat frequency response, preserves original audio tone, effectively eliminates ground loop buzzing noise
• High-grade silicon steel EI19 core, low core loss and low temperature rise under continuous 170V working condition
• Horizontal low-profile design, stable pin structure, good vibration resistance for PCB assembly
• Strict parameter consistency across mass production, less unit-to-unit variation than many competing brands
• RoHS, CE & ISO9001 certified, factory direct supply, shorter lead time and competitive pricing. We support custom turns ratio, inductance and insulation specs for your audio projects
