LP-34-340

Power Transformers Overview

The LP-34-340 is a board-mount power transformer from the LP series, designed for 50/60 Hz operation. It features a hum-bucking semi-toroidal construction to minimize electromagnetic interference. The unit has a power rating of 12 VA with primary voltage ratings of 115 VAC and 230 VAC. Secondary options include 34 VCT at 340 mA or 17 V at 680 mA. Physical dimensions are 63.5 mm in length and 27.1 mm in height, utilizing through-hole mounting.

Power Transformers Feature Summary

• Semi-toroidal hum-bucking construction reduces magnetic noise
• Dual primary voltage capability for global compatibility
• Through-hole PCB mounting for secure installation

Power Transformers Applications

• General purpose AC power supply circuits
• Industrial control equipment
• Consumer electronics requiring isolated power

Power Transformers Procurement Notes

Verify the specific secondary configuration required, as the part number denotes the 34 VCT variant. Confirm that the 12 VA power rating meets the load requirements of the target application. Ensure the through-hole footprint matches the printed circuit board design. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Power Transformers Selection Notes

Select this component when low magnetic noise is critical due to its semi-toroidal design. Choose based on the need for dual primary voltage support without switching components. Consider the physical size constraints, as the through-hole package requires specific board space. Validate that the 340 mA secondary current capacity aligns with the system's power consumption needs.

Power Transformers Part Context

This transformer belongs to the LP series, which utilizes semi-toroidal cores for improved performance over standard laminated designs. The series offers various voltage configurations tailored for different power requirements. The LP-34-340 specifically addresses applications needing moderate power isolation with reduced electromagnetic interference characteristics compared to conventional transformers.

Power Transformers Replacement Considerations

Direct substitutes must match the 12 VA rating, 34 VCT secondary, and semi-toroidal construction. Verify pinout compatibility and physical dimensions before swapping. Alternative parts may require re-evaluation of thermal management and mounting hole spacing.
