PMCU-7039

Overview

The PMCU-7039 is a through-hole common mode filter manufactured by Premier Magnetics. It features an inductance of 900uH measured at 1kHz, with a maximum DC resistance of 120mOhm and insulation resistance of 100MΩ. The component supports a current rating of 2A and operates within a temperature range of -40°C to +80°C. It has a voltage rating of 250V AC and provides 2kV isolation.

Feature Summary

• Provides effective common mode noise suppression for power lines
• Designed for robust performance in industrial environments
• Utilizes through-hole mounting for secure PCB integration

Applications

• Power supply input filtering
• Industrial equipment EMI reduction
• Signal conditioning circuits

Procurement Notes

Verify the specific datasheet version for the PMCU-7039 to confirm exact electrical tolerances and mechanical dimensions before finalizing design integration. Ensure that the through-hole footprint matches the target PCB layout requirements. Cross-reference manufacturer documentation to validate compliance with relevant safety standards applicable to your region.

Selection Notes

Select this component when a 900uH inductance value is required for common mode noise attenuation in low-frequency applications. The 2A current rating suits moderate power line filtering needs. Consider the through-hole package if mechanical stability is prioritized over surface area constraints compared to SMD alternatives.
