PC-120-35

Power Transformers Overview

The PC-120-35 is a laminated core power transformer from the PC series by Signal Transformer. It features a single primary winding rated for 115 VAC and dual secondary windings providing 60V at 70mA and 120VCT at 35mA. The unit has a power rating of 4.4 VA and operates within a frequency range of 50 Hz to 500 Hz. Designed for through-hole mounting, it measures 34.9 mm in length, 28.6 mm in width, and 30.15 mm in height. The device supports dielectric strength testing up to 1500 Vrms.

Power Transformers Feature Summary

• Operates without voltage degradation across a wide frequency range from 50 Hz to 500 Hz
• Features a laminated core construction for efficient power transformation
• Supports multiple secondary output configurations including parallel and center-tapped connections

Power Transformers Applications

• General purpose AC power supply circuits
• Industrial control systems requiring isolated power
• Electronic equipment needing 50-500 Hz operation

Power Transformers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing details may update. Confirm that the through-hole package dimensions match your PCB layout constraints. Ensure the 4.4 VA power rating meets the load requirements of your application. Check for RoHS compliance status if environmental regulations apply to your production process.

Power Transformers Selection Notes

Choose this component when a wide frequency tolerance between 50 Hz and 500 Hz is required. Select this model if the application demands a laminated core design rather than an epoxy potting style. Consider the physical footprint of 34.9 x 28.6 mm for board space planning. Verify that the 115 VAC primary input matches your source voltage availability.

Power Transformers Part Context

This part belongs to the PC series of printed circuit mount power transformers. The series is characterized by its ability to maintain output stability across varying frequencies. It serves as a standard isolation component in low-power electronic designs where compact size and reliable performance are prioritized over high-frequency switching capabilities.

Power Transformers Replacement Considerations

The PC-120-10 is listed in cross-reference data but offers different current ratings (10 mA vs 70 mA). Verify electrical compatibility before substitution. No other direct substitutes are confirmed in public documentation.
