183J36

Power Transformers Overview

The Hammond Manufacturing 183J36 is a low voltage power transformer designed for PCB mounting within the 183 Series. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The secondary configuration provides a 36 VAC center-tapped output with a maximum current rating of 820 mA, delivering a total power capacity of 30 VA. Constructed with a laminated core, this component utilizes through-hole solder pin termination for secure board integration. It operates within a temperature range of 0°C to +155°C and offers 4000Vrms isolation voltage between windings.

Power Transformers Feature Summary

• Dual primary winding design supports universal input voltage compatibility for 115V and 230V AC systems.
• Center-tapped secondary architecture enables flexible rectification and bipolar power supply configurations.
• Laminated core construction ensures efficient magnetic flux transfer with minimal energy loss.
• Through-hole solder pin termination provides robust mechanical stability on printed circuit boards.

Power Transformers Applications

• Low voltage electronic equipment requiring isolated AC power sources
• Industrial control panels utilizing standard mains input voltages
• Audio amplifier circuits needing balanced or split-rail power supplies
• Test and measurement instrumentation requiring stable secondary outputs

Power Transformers Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 30 VA power rating and 36V CT secondary configuration. Confirm compliance with RoHS directives if environmental regulations apply to your manufacturing process. Ensure the physical dimensions fit the designated PCB footprint, as the unit requires through-hole mounting with specific pin spacing. Check datasheet details for thermal management requirements given the maximum operating temperature limit.

Power Transformers Selection Notes

Select this transformer when a compact, board-mount solution is needed for converting standard line voltages to lower AC levels. The dual primary feature simplifies global product distribution by accommodating different regional mains standards without changing hardware. Consider the 30 VA capacity against the load requirements to ensure adequate headroom. The center-tapped output is essential for applications requiring symmetrical positive and negative DC rails after rectification.

Power Transformers Part Context

This component belongs to the Hammond Manufacturing 183 Series, which specializes in low voltage power transformers for general-purpose applications. The series offers various power ratings and voltage configurations to suit diverse electronic designs. As a board-mount device, it integrates directly into assemblies where space efficiency and reliable electrical isolation are prioritized over high-power industrial demands.

Power Transformers Replacement Considerations

Direct substitutes within the same series include the 183G36 (10 VA) and 183K36 (56 VA), though these differ significantly in power capacity and physical size. Verify that any replacement maintains the 36V CT secondary specification and compatible primary voltage ratings. Dimensional changes may require PCB redesign or mechanical adaptation when moving between different power tiers in the 183 lineup.
