104B

Overview

The Hammond Manufacturing 104B is a miniature audio transformer featuring epoxy potting for enhanced durability and environmental resistance. Designed for signal coupling applications, this component provides electrical isolation between circuits while maintaining audio fidelity. The unit utilizes a compact form factor suitable for space-constrained installations in consumer electronics and industrial control systems requiring reliable analog signal transmission.

Feature Summary

• Epoxy potted construction ensures protection against moisture and mechanical vibration
• Miniature design facilitates integration into compact electronic assemblies
• Provides galvanic isolation for audio signal paths

Applications

• Audio signal coupling in consumer electronics
• Interstage coupling in amplifier circuits
• Impedance matching in low-power audio systems

Procurement Notes

Verify the specific winding configuration and impedance ratio required for your circuit design before ordering. Confirm that the epoxy potting meets the thermal and chemical resistance standards of your operating environment. Ensure compatibility with existing PCB layouts or mounting hardware to avoid integration issues during assembly.

Selection Notes

Select the 104B when miniature size and robust environmental sealing are prioritized over high-power handling capabilities. This model is appropriate for low-voltage audio signals rather than power distribution. Evaluate the frequency response requirements against standard audio bandwidths to ensure performance suitability for the intended application.

Part Context

This component belongs to Hammond Manufacturing's line of miniature audio transformers. It is distinct from their enclosure products and general-purpose power transformers. The 104B serves as a specialized passive component for analog signal processing within larger electronic systems.
