EI30 Encapsulated PCB Mount Audio Transformers 600:600 Ohm For Audio Equipment

The EI30 Potted Audio Transformer is a high-precision magnetic component engineered for professional audio signal coupling, isolation, and impedance matching. Unlike standard open-frame units, the EI30 series is fully encapsulated in high-grade epoxy resin within a flame-retardant plastic casing. This "potted" design is specifically intended for modern PCB layouts where electronic components must withstand harsh environmental conditions while delivering transparent, high-fidelity audio performance across the entire audible spectrum.

• Fully Sealed Architecture: The windings and the EI30 core are vacuum-impregnated and hermetically sealed in epoxy, providing an IP67-level barrier against moisture, oxidation, and industrial pollutants.
• Integrated PCB Mounting: Equipped with precision-aligned, tinned copper pins for seamless through-hole soldering, ensuring mechanical stability and electrical reliability.
• Linear Frequency Response: Optimized winding techniques ensure a flat response from 20Hz to 20KHz, maintaining the sonic characteristics of the original signal with minimal phase deviation.
• High Dielectric Strength: The potting material significantly enhances the internal insulation, providing isolation voltages typically up to 4.0kV AC.

• Professional Audio Equipment: Essential for mixing consoles, high-end preamplifiers, and signal processors requiring line-level isolation.
• Telecom & Intercom Systems: Provides reliable impedance matching for broadband communication and emergency broadcasting hardware.
• Industrial Control Modules: Used in sensitive analog sensor circuits where ground-loop elimination and surge protection are mandatory.
• Outdoor Audio Electronics: Ideal for public address systems and marine audio modules where humidity and temperature fluctuations are extreme.

• Unrivaled Durability: The solid-state potting makes the transformer virtually immune to physical shocks and high-vibration environments, extending the service life to over 20 years.
• Noise-Free Operation: The encapsulation effectively dampens electromagnetic humming (magnetostriction), making it suitable for silent-operation environments like recording studios and medical labs.
• Ease of Assembly: The standardized PCB footprint and robust casing allow for easy handling by automated pick-and-place equipment and wave-soldering processes.
• Superior Safety Compliance: Built using UL94-V0 flame-retardant materials and meeting international safety standards (CE, RoHS), simplifying the end-product's global certification process.
