107V-BULK

Overview

The 107V-BULK is an audio signal transformer manufactured by Hammond Manufacturing, designed for impedance matching and signal isolation in electronic circuits. It features a potted epoxy construction to secure internal windings and protect against environmental factors. The unit provides a primary impedance of 25,000 ohms center-tapped and a secondary impedance of 600 ohms center-tapped. This configuration supports balanced line applications requiring precise voltage transformation ratios.

Feature Summary

• Center-tapped primary winding with 25k ohm impedance
• Center-tapped secondary winding with 600 ohm impedance
• Epoxy-potted housing for mechanical stability

Applications

• Audio signal transmission systems
• Impedance matching between circuit stages
• Balanced line interfacing

Procurement Notes

Verify the specific suffix 'BULK' indicates loose packaging rather than reel or tape configuration when reviewing distributor listings. Confirm that the component matches the standard 107V electrical specifications without deviation. Ensure the supplier source is authorized to guarantee the integrity of the potted assembly and winding continuity.

Selection Notes

Select this model when a fixed 25k-to-600 ohm center-tapped ratio is required for audio frequency operations. Evaluate the physical dimensions and mounting constraints relative to the target enclosure space. Consider the thermal characteristics of the epoxy potting compound if the operating environment involves significant temperature fluctuations.

Part Context

This component belongs to the series of miniature audio transformers produced by Hammond Manufacturing. These units are typically utilized in professional audio equipment and communication devices where reliable signal transfer and galvanic isolation are necessary. The design prioritizes compact form factors suitable for dense circuit board layouts.
