183F20

Power Transformers Overview

The Hammond Manufacturing 183F20 is a laminated core power transformer with a 5VA maximum power rating. It features dual primary windings for 115V and 230V operation and dual secondary windings providing parallel 10V or series 20V outputs. The maximum output current is 500mA in parallel configuration and 250mA in series configuration. This component utilizes through-hole PC pin termination, measures 41.28mm in length and 36.50mm in width, and has a maximum installed height of 34.93mm. It offers 4000Vrms isolation voltage and operates at a maximum temperature of +155°C.

Power Transformers Feature Summary

• Dual primary winding design supports both 115V and 230V input voltages.
• Flexible secondary output options allow for parallel 10V or series 20V configurations.
• Laminated core construction provides robust electrical isolation.

Power Transformers Applications

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

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm the exact secondary current ratings, as distributor listings may vary between 2A/1A and 500mA/250mA specifications. Ensure the package type matches the PCB layout requirements for through-hole mounting. Confirm RoHS compliance status if required by project regulations.

Power Transformers Selection Notes

Select this model when a 5VA laminated core transformer is needed for universal input voltage applications. Consider the physical dimensions of 41.28mm x 36.50mm for board space constraints. Choose based on the required secondary voltage configuration, either parallel 10V or series 20V, and verify the current demand does not exceed the rated limits.

Power Transformers Part Context

This component belongs to the Hammond Manufacturing 183 Series, which covers a range of low voltage PCB mount power transformers from 2.5VA to 56VA. The series is designed for general-purpose power conversion in electronic assemblies requiring reliable isolation and standard through-hole integration.

Power Transformers Replacement Considerations

Cross-reference with other Hammond 183 series models such as 183F12 or 183F24 for similar power ratings but different voltage outputs. Verify that any substitute part matches the primary voltage, secondary configuration, and physical footprint requirements before implementation.
