145H

Overview

The Hammond Manufacturing 145H is an audio signal transformer designed for impedance matching applications. It features a primary resistance of 148 Ohms and supports a 2K/500CT impedance configuration. This component belongs to the 145 series of audio transformers, intended for use in electronic circuits requiring signal isolation or level adjustment.

Feature Summary

Provides impedance transformation between 2K and 500CT configurations
Designed specifically for audio signal processing applications

Applications

Audio equipment signal conditioning
Impedance matching in audio circuits
Signal isolation in professional audio systems

Procurement Notes

Verify the specific impedance ratio and pinout configuration against your circuit design requirements before procurement. Confirm that the primary resistance value of 148 Ohms aligns with your source impedance needs. Ensure compatibility with your existing audio infrastructure regarding frequency response characteristics not detailed in basic specifications.

Selection Notes

Select this component when a fixed 2K to 500CT impedance transformation is required for audio signals. Consider the physical mounting style and lead configuration if integrating into custom PCBs or chassis assemblies. Evaluate thermal performance if operating in enclosed environments, as datasheet thermal limits are not explicitly provided in available summaries.

Part Context

This transformer is part of Hammond Manufacturing's broader range of audio and signal transformers. The 145 series typically offers standardized impedance ratios for common audio interface requirements. Hammond Manufacturing specializes in enclosures and electrical components, providing reliable passive components for industrial and commercial audio applications.

Replacement Considerations

Consult manufacturer cross-reference lists for direct equivalents. Verify that any substitute maintains the exact 2K/500CT impedance ratio and similar primary resistance to ensure circuit performance integrity without redesign.
