107H

Overview

The Hammond Manufacturing 107H is an audio signal transformer designed for through-hole mounting. It features epoxy potting for environmental protection and durability. The device provides a balanced audio interface with a primary winding impedance of 600 ohms center-tapped and a secondary winding impedance of 600 ohms center-tapped. This configuration supports standard audio line-level applications requiring impedance matching and isolation between circuit stages.

Feature Summary

• Epoxy potted construction for enhanced mechanical stability and environmental resistance
• Center-tapped windings on both primary and secondary sides for balanced signal handling
• Through-hole mounting style suitable for printed circuit board integration

Applications

• Audio signal transmission in professional sound equipment
• Impedance matching between audio source and load circuits
• Balanced line driver and receiver interfaces

Procurement Notes

Verify the specific datasheet version to confirm pinout orientation and exact physical dimensions before PCB layout finalization. Ensure that the through-hole footprint matches the manufacturer's recommended land pattern. Confirm that the epoxy potting material meets the thermal requirements of the intended operating environment.

Selection Notes

Select this component when a balanced 600-ohm audio interface is required with robust physical protection. The center-tapped design facilitates ground referencing in balanced lines. Consider the through-hole form factor if surface-mount alternatives are unsuitable for the assembly process or mechanical stress requirements.

Part Context

This transformer belongs to Hammond Manufacturing's range of audio signal transformers. It serves as a passive component for signal conditioning rather than power conversion. The 600-ohm standard aligns with traditional telephony and professional audio industry norms for consistent signal transfer across various equipment types.
