101H

Overview

The Hammond Manufacturing 101H is an audio transformer featuring a 1.2kCT primary winding and a 600CT secondary winding, designed for balanced audio signal transmission. Constructed with a steel core and epoxy encapsulation, it provides electrical isolation between circuits while maintaining signal integrity in low-voltage applications. The component utilizes through-hole mounting technology for secure PCB integration. It operates within standard industrial temperature ranges and meets UL safety standards for electronic components. This transformer supports impedance matching between source and load circuits without introducing significant harmonic distortion or phase shift during operation.

Feature Summary

• Provides galvanic isolation between input and output circuits to prevent ground loops
• Maintains signal balance in differential audio transmission paths
• Epoxy encapsulation protects internal windings from environmental factors

Applications

• Balanced line-level audio signal interfacing
• Impedance matching between audio stages
• Ground loop noise elimination in recording systems

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing revisions may alter pinout configurations or mechanical dimensions. Confirm that the supplier provides original manufacturer packaging to ensure component authenticity. Request batch traceability documentation if the application requires strict quality control records. Ensure the receiving facility has appropriate ESD protection protocols during handling.

Selection Notes

Select this model when a 1.2kCT to 600CT impedance transformation ratio is required for balanced audio interfaces. Consider the physical footprint constraints of the target PCB layout before finalizing the design. Evaluate thermal dissipation requirements if the transformer will operate near maximum rated current levels continuously.
