PMCU-5056

Overview

The Premier Magnetics PMCU-5056 is a two-line through-hole common mode choke designed for electromagnetic interference suppression. It features an inductance of 5.6 mH measured at 1 kHz and supports a maximum current rating of 450 mA. The component has a maximum DC resistance of 1 Ohm and an AC voltage rating of 250 V. Its low-profile construction facilitates integration into space-constrained circuit boards while maintaining specified isolation voltage and insulation resistance standards.

Feature Summary

• Low-profile construction for compact board integration
• Defined isolation voltage and insulation resistance specifications
• Controlled temperature rise limits under rated current conditions

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply input stages requiring common mode noise reduction
• Signal line protection against high-frequency disturbances

Procurement Notes

Verify the specific package type and lead configuration against your PCB footprint requirements before ordering. Confirm that the 450 mA current rating and 1 Ohm DC resistance meet your circuit's electrical constraints. Ensure the 250 V AC voltage rating is sufficient for your operating environment. Check for any specific mounting orientation requirements due to the low-profile design.

Selection Notes

Select this component when a 5.6 mH inductance at 1 kHz is required for common mode noise suppression. Ensure the application can accommodate the 450 mA maximum current rating without exceeding thermal limits. Verify that the through-hole mounting style aligns with your manufacturing process. Consider the 1 Ohm DC resistance impact on signal integrity or power loss in your specific circuit design.

Part Context

This component belongs to the Premier Magnetics PMCU series of common mode chokes. The series offers various inductance and current ratings to suit different filtering needs. The PMCU-5056 specifically targets applications requiring moderate inductance with a compact form factor. It is part of a broader range of passive components designed for EMI mitigation in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes with identical 5.6 mH inductance, 450 mA rating, and 1 Ohm DCR. Verify pin compatibility and physical dimensions for drop-in replacement. Ensure equivalent AC voltage ratings and thermal performance characteristics match the original specification.
