LP-120-50

Power Transformers Overview

The LP-120-50 is a board-mount power transformer from the LP series by Signal Transformer. It features a semi-toroidal hum-bucking construction for reduced electromagnetic interference. The unit supports dual primary voltages of 115 VAC and 230 VAC with parallel winding configuration. Secondary outputs include 120 VCT at 50 mA and 60 V at 100 mA. Rated at 6 VA, it operates at 50 Hz/60 Hz frequencies. Dimensions are 47.5 mm in length, 28.6 mm in width, and 21.6 mm in height. It utilizes through-hole solder pin termination for PCB integration.

Power Transformers Feature Summary

• Semi-toroidal hum-bucking construction minimizes magnetic field leakage
• Dual primary winding allows flexible voltage input selection
• Through-hole solder pin termination ensures secure PCB mounting

Power Transformers Applications

• Industrial control equipment requiring low-noise power conversion
• Electronic instrumentation utilizing split secondary voltage rails
• Consumer electronics assemblies needing compact board-mount transformers

Power Transformers Procurement Notes

Verify that the specific order matches the LP-120-50 designation to ensure correct secondary current ratings. Confirm that the application environment remains within the specified operating temperature range. Ensure PCB layout accommodates the physical dimensions and solder pin spacing. Check for updated RoHS compliance documentation if required by regional regulations before finalizing procurement.

Power Transformers Selection Notes

Select this component when a compact, low-profile transformer with reduced hum is necessary. The dual primary design offers versatility for different input regions. The split secondary output is suitable for circuits requiring balanced or dual-polarity supplies. Consider the 6 VA power limit to ensure adequate capacity for the load. Verify that the through-hole mounting style aligns with the manufacturing process.

Power Transformers Part Context

The LP series represents Signal Transformer's line of laminated power transformers designed for board mount applications. These units utilize a semi-toroidal core geometry to improve efficiency and reduce acoustic noise compared to standard EI cores. The series provides various power ratings and voltage configurations to support diverse electronic design requirements while maintaining a small footprint.

Power Transformers Replacement Considerations

Direct substitutes must match the 6 VA rating, 115/230 VAC primary, and 120VCT/60V secondary specifications. Verify that alternative components maintain the same semi-toroidal construction and through-hole pin configuration. Ensure dimensional compatibility with the existing PCB footprint to avoid mechanical interference during assembly.
