229A34

Power Transformers Overview

The Hammond Manufacturing 229A34 is a low-profile, semi-toroidal power transformer designed for PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz/60 Hz frequencies. The secondary output provides 34 VAC center-tapped configuration, delivering 170 mA at the full 34 V rating and 340 mA at the half-winding 17 V rating. With a 6 VA power rating, it utilizes through-hole solder pin termination. The unit measures 47.75 mm in length, 39.62 mm in width, and 21.59 mm in height, operating within a temperature range of 0°C to +130°C.

• Center-tapped secondary winding for versatile rectification configurations
• Through-hole solder pin termination for direct PCB integration

Power Transformers Applications

• Low voltage AC power supply circuits
• Industrial control panel transformers
• Audio equipment power stages
• Consumer electronics internal power conversion

Power Transformers Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm electrical tolerances and insulation class. Ensure the ordering part number matches the required secondary current ratings for your circuit design. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Cross-reference the physical dimensions with your PCB footprint requirements before finalizing procurement orders.

Power Transformers Selection Notes

Select this component when a compact form factor is critical for board space constraints. The dual primary winding allows compatibility with both 115V and 230V mains inputs without rewiring. Choose this model if the application requires a center-tapped secondary output for bridge or full-wave rectifier circuits. Verify that the 6 VA power rating meets the maximum load requirements of the downstream electronic components.

Power Transformers Part Context

This transformer belongs to the Hammond 229 Series, which specializes in low-voltage, low-profile power solutions. The series is characterized by semi-toroidal geometry, offering higher efficiency and lower magnetic interference compared to standard laminated cores. These units are engineered specifically for surface-mounted or through-hole PCB applications where spatial limitations restrict the use of larger chassis-mounted alternatives.

Power Transformers Replacement Considerations

Direct substitutes include other Hammond 229 series variants with matching 6 VA ratings and similar secondary voltage outputs, such as the 229A20 or 229A56, provided the voltage specifications align with the system requirements. Ensure any replacement maintains the same physical envelope dimensions and pinout configuration to fit existing PCB layouts.
