164J16

Overview

The Hammond Manufacturing 164J16 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 16 VAC center-tapped output. The unit delivers a total power rating of 36 VA, with secondary current capabilities of 2.25 A per leg or 4.5 A in parallel configuration. Constructed with a laminated core, it utilizes solder pin termination for through-hole installation. The physical dimensions are 2.63 inches in length, 2.19 inches in width, and 1.56 inches in height. It operates within a temperature range of 0°C to +130°C.

Feature Summary

• Low profile design optimized for printed circuit board mounting applications
• Dual secondary winding architecture supporting series or parallel connection modes
• Laminated core construction ensuring efficient power transformation

Applications

• General purpose electronic equipment requiring isolated AC power
• Industrial control systems utilizing low voltage DC rectification
• Consumer electronics assemblies needing compact power sources

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm electrical tolerances and insulation ratings. Ensure that the intended operating environment remains within the specified thermal limits of plus one hundred thirty degrees Celsius. Confirm that the PCB layout accommodates the through-hole solder pin termination style and the physical footprint dimensions provided in the dimensional drawings. Check for compliance requirements such as RoHS status relevant to the target market regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact, board-mount solution is required for 115 VAC input conversion. The 16 VAC center-tapped output suits bridge rectifier circuits generating positive and negative DC rails. Consider the 36 VA power limit to ensure adequate headroom for peak loads. The through-hole mounting method provides mechanical stability compared to surface mount alternatives. Evaluate the physical size constraints against available PCB real estate before integration into the final assembly design.

Part Context

This transformer belongs to the Hammond 162/164 Series, which focuses on low-profile power solutions for space-constrained designs. The series offers various voltage and wattage combinations tailored for industrial and commercial applications. The 164J16 specifically addresses needs for moderate power levels where direct PCB mounting simplifies assembly processes. It represents a standard offering within Hammond's portfolio of laminated core transformers designed for reliability and consistent performance in regulated environments.

Replacement Considerations

Cross-reference part numbers such as 162J16 or other variants within the 164 series for alternative voltage configurations. Verify that any substitute maintains identical mounting hole patterns and terminal spacing to ensure mechanical compatibility. Electrical parameters including VA rating and isolation voltage must meet or exceed original specifications. Consult official replacement guides from Hammond Manufacturing to confirm functional equivalence without redesigning the PCB layout.
