PMCU-0056

Overview

The PMCU-0056 is a two-line common mode choke manufactured by Premier Magnetics, designed for through-hole mounting. It features a maximum DC resistance of 400mOhm and supports a current rating of 1A. The component operates within an AC voltage rating of 250V and functions reliably across a temperature range of -40°C to 80°C.

Feature Summary

• Provides common mode noise suppression for dual-line applications
• Designed for reliable through-hole PCB integration
• Engineered for stable operation in varying thermal environments

Applications

• AC power line filtering
• EMI suppression in electronic equipment
• Signal integrity protection in data lines

Procurement Notes

Verify the specific datasheet version for the PMCU-0056 to confirm exact impedance characteristics at target frequencies. Ensure that the through-hole footprint dimensions align with your PCB layout requirements. Confirm that the 1A current rating meets the operational demands of your circuit under all expected load conditions.

Selection Notes

Select this component when a low-profile, through-hole solution is required for common mode interference reduction. Consider the 400mOhm DCR limit to ensure minimal voltage drop in your design. Verify that the 250V AC rating is sufficient for your specific line voltage application before finalizing the schematic.

Part Context

This part belongs to the PMCU series of EMI/RFI common mode line filters from Premier Magnetics. These components are typically utilized in general-purpose electronic devices where compact magnetic filtering is necessary. The series offers standardized mounting options suitable for automated assembly processes.

Replacement Considerations

Cross-reference with other Premier Magnetics CMC parts such as PMCU-4009 if different current ratings are needed. Ensure any substitute maintains the same through-hole package and similar electrical parameters to avoid redesigning the PCB footprint.
