106EE

Overview

The Hammond Manufacturing 106EE is a miniature epoxy-encapsulated audio transformer designed for through-hole mounting. It features a primary impedance of 600CT ohms and a secondary impedance of 600 ohms, with a DC resistance of 65 ohms on the primary side. The unit supports a power level of 500mW and operates within a frequency range starting at 150Hz. Electrical isolation is rated at 200V, while insertion loss is specified at 1dB. The component measures 1.080 inches in length, 0.880 inches in width, and has a maximum installation height of 0.950 inches.

Feature Summary

• Miniature epoxy encapsulation provides physical protection and environmental sealing for the internal windings.
• Center-tapped primary winding configuration enables balanced signal transmission and impedance matching applications.
• Through-hole PC pin termination ensures secure mechanical attachment to printed circuit boards.

Applications

• Audio signal coupling in communication equipment
• Impedance matching between audio stages
• Balanced line interfacing in professional audio systems

Procurement Notes

Verify that the specific order matches the 106EE part number rather than similar variants like 106E or 106Q, as impedance and power ratings differ significantly across the series. Confirm RoHS3 compliance status if environmental regulations apply to the assembly. Ensure PCB layout accommodates the specified through-hole dimensions and height constraints during final integration.

Selection Notes

Select this component when a 600CT to 600 ohm audio transformer is required for low-power applications up to 500mW. The 150Hz lower frequency limit dictates suitability for voice-band or specific audio frequencies rather than full-range high-fidelity reproduction. Consider the physical size and mounting style against available board space and mechanical stress requirements.

Part Context

This component belongs to the Hammond Manufacturing 106 series of miniature audio transformers. The series utilizes a consistent form factor with varying electrical specifications to suit different impedance networks. The 106EE variant specifically addresses standard telephone-line or broadcast audio impedances requiring center-tapped primary configurations.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with existing circuit designs before considering alternative manufacturers or models.
