164F20

Overview

The Hammond Manufacturing 164F20 is a low voltage PCB mount power transformer featuring a laminated core and low profile design. It operates with a single primary winding rated at 115 VAC. The dual secondary windings provide a center-tapped output of 20 VAC, supporting a total power rating of 6 VA. The component delivers a maximum secondary current of 300 mA in series configuration or 600 mA in parallel. Designed for through-hole installation, it utilizes solder pin termination. The unit measures 1.63 inches in length, 1.31 inches in width, and 1.31 inches in height.

Feature Summary

• Low profile construction suitable for space-constrained printed circuit board applications
• Dual secondary winding architecture enabling flexible series or parallel connection options
• Laminated core design providing efficient magnetic coupling for power conversion

Applications

• Low voltage power supply circuits requiring isolated AC-to-AC transformation
• Electronic equipment utilizing center-tapped rectifier configurations
• Industrial control systems needing compact board-mount isolation transformers

Procurement Notes

Verify the specific secondary current requirement against the datasheet before ordering. Confirm whether the application requires series (300 mA) or parallel (600 mA) secondary operation to ensure adequate capacity. Check mechanical dimensions against the PCB layout to ensure the 1.63 x 1.31 x 1.31 inch footprint fits within the designated area. Ensure the mounting holes align with the through-hole specification.

Selection Notes

Select this model when a 6 VA rating is sufficient for the load. Choose the 164F20 over other variants if the 20 VAC center-tapped output matches the system voltage requirements. Consider the physical size constraints as the low profile design may limit thermal dissipation compared to larger transformers. Verify that the 115 VAC primary input is compatible with the available line voltage.

Part Context

This component belongs to the Hammond 164 series of low voltage PCB mount transformers. The series offers various voltage and power ratings to suit different electronic designs. The 164F20 specifically addresses applications requiring moderate power isolation with a center-tapped secondary. It shares the same physical envelope and mounting style as other models in the family, such as the 164F120 and 164F48, differing primarily in electrical specifications.

Replacement Considerations

The 164F20 can be replaced by other Hammond 164 series transformers if voltage or current requirements differ. Ensure any substitute maintains the 115 VAC primary rating and through-hole mounting style. Verify that the replacement part provides equal or greater VA rating and compatible secondary voltage configurations.
