PC-120-10

Power Transformers Overview

The PC-120-10 is a laminated core power transformer from the PC series by Signal Transformer, designed for board mount applications. It features a single primary winding rated at 115 VAC and dual secondary windings providing 120 VCT/60 V outputs. The unit has a power rating of 1.2 VA with secondary current ratings of 10 mA and 20 mA respectively. It utilizes through-hole mounting and measures 34.9 mm in length, 28.6 mm in width, and 30.15 mm in height.

Power Transformers Feature Summary

• Dual secondary winding configuration supporting center-tapped or parallel output connections
• Laminated core construction optimized for standard operating frequencies
• Through-hole mounting style for secure PCB integration

Power Transformers Applications

• Power supply circuits requiring isolated AC voltage transformation
• Audio equipment signal conditioning stages
• Industrial control systems utilizing low-power AC sources

Power Transformers Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributors, as documentation indicates details are available but not explicitly confirmed in all summaries. Ensure the specific ordering suffix matches the required voltage and current specifications. Confirm that the through-hole pin spacing aligns with your PCB footprint design before finalizing procurement orders to avoid mechanical integration issues.

Power Transformers Selection Notes

Select this component when a 1.2 VA capacity is sufficient for the load requirements. The dual secondary option allows flexibility for creating split-rail supplies or higher current parallel configurations. Consider the physical dimensions of 34.9 x 28.6 x 30.15 mm to ensure adequate clearance within the enclosure. Verify that the 115 VAC primary input matches the available line voltage in the target application environment.

Power Transformers Part Context

This transformer belongs to the PC series, which offers various power ratings and winding configurations for general-purpose power conversion. The PC-120-10 specifically addresses needs for moderate isolation and voltage step-up or step-down functions in compact electronic assemblies. It serves as a fundamental building block for AC-powered devices requiring galvanic isolation between primary mains and secondary circuitry.

Power Transformers Replacement Considerations

Direct substitutes must match the 1.2 VA rating, 115 VAC primary, and 120 VCT/60 V secondary specifications. Check for identical mounting hole patterns and overall envelope dimensions to ensure compatibility with existing PCB layouts. Verify that alternative components maintain similar thermal performance and insulation class ratings for safe operation.
