226D

Power Transformers Overview

The Hammond Manufacturing 226D is a semi-toroidal audio transformer designed for signal coupling applications. It features a primary voltage rating of 115V and provides an impedance transformation from 20KCT to 20KCT. The unit handles a power capacity of 3.4W and utilizes PC pin termination style for circuit board mounting. The physical dimensions are 43.94mm in length by 34.29mm in width, classifying it as a compact component suitable for integrated audio equipment designs.

Power Transformers Feature Summary

• Semi-toroidal core construction for efficient magnetic coupling
• Specific impedance matching between 20KCT primary and secondary windings
• PC pin termination for direct printed circuit board integration

Power Transformers Applications

• Audio signal coupling circuits
• Impedance matching in audio amplifiers
• Electronic audio equipment internal components

Power Transformers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer specifications may be updated. Confirm that the PC pin pitch matches your PCB footprint requirements. Ensure the 115V primary rating aligns with your system's input voltage standards. Check for any RoHS compliance documentation if required by your manufacturing regulations.

Power Transformers Selection Notes

Select this component when a fixed 20KCT to 20KCT impedance ratio is required for audio stages. The semi-toroidal design offers a balance between performance and size constraints. Consider the 3.4W power handling limit when designing for high-output audio signals. The PC pin format dictates the assembly method, requiring through-hole soldering processes.

Power Transformers Part Context

This component belongs to Hammond Manufacturing's range of electronic transformers. Unlike their industrial enclosures or rack slides, the 226D is an active electronic passive component used within circuit assemblies. It serves a specialized role in audio electronics rather than structural or housing functions.

Power Transformers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing circuit designs before attempting substitution.
