164F28

Overview

The Hammond Manufacturing 164F28 is a low voltage power transformer designed for PCB mounting. It features a single primary winding rated at 115 VAC and dual secondary windings providing 28 VAC center-tapped output. The unit has a power rating of 6 VA with a secondary current capacity of 200 mA per leg. Physical dimensions are 1.63 inches in length, 1.31 inches in width, and 1.31 inches in height. It utilizes solder pin termination for through-hole installation and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Low profile design suitable for space-constrained printed circuit board applications
• Dual secondary windings enable flexible center-tapped or split voltage configurations
• Through-hole solder pin termination ensures secure mechanical and electrical connection

Applications

• Low voltage AC power supply circuits
• Industrial control panel instrumentation
• Electronic equipment requiring isolated power conversion

Procurement Notes

Verify the specific secondary configuration requirements against the datasheet before ordering. Confirm that the 115V primary input matches the target application voltage. Ensure the PCB footprint accommodates the specified lead spacing and physical dimensions. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a compact, low-voltage transformer with dual secondary outputs is required. Compare the 6 VA rating against total load consumption to ensure adequate headroom. Consider the through-hole mounting style versus surface mount alternatives based on assembly capabilities. Evaluate thermal performance within the enclosed environment given the 130°C maximum operating limit.

Part Context

This part belongs to the Hammond 164 series of laminated core power transformers. The series offers various voltage and wattage combinations tailored for general-purpose industrial and commercial electronics. These units are characterized by their robust construction and standardized form factors compatible with common PCB layouts.

Replacement Considerations

Direct substitutes include other Hammond 164 series variants with matching 6 VA ratings and 115V primary inputs. Verify that alternative models maintain identical secondary voltage and current specifications. Cross-reference physical dimensions to ensure mechanical fit within the existing enclosure and PCB constraints.
