PMCU-0330

Overview

The PMCU-0330 is a two-line common mode choke manufactured by Premier Magnetics, designed for through-hole mounting. It features an inductance of 33 mH measured at 1 kHz and supports a maximum current rating of 400 mA. The component has a DC resistance (DCR) of 2 Ohms. It serves as an EMI/RFI line filter within the PMCU-XXXX series, providing noise suppression for power lines.

Feature Summary

• Provides common mode noise attenuation for two-line circuits
• Designed for through-hole PCB integration
• Functions as an EMI/RFI line filter

Applications

• Power supply input filtering
• EMI suppression in electronic equipment
• RFI noise reduction in AC/DC conversion stages

Procurement Notes

Verify the specific datasheet version for the PMCU-0330 to confirm mechanical dimensions and thermal ratings. Ensure the selected variant matches the required 400 mA current handling and 33 mH inductance specifications. Cross-reference with official Premier Magnetics documentation to validate compliance with intended electromagnetic interference standards.

Selection Notes

Select this component when a 33 mH common mode inductance is required for two-line applications. The 400 mA rating determines the maximum operational current capacity. Consider the through-hole package type for board layout compatibility. Verify that the 2 Ohm DCR aligns with system voltage drop requirements.

Part Context

This part belongs to the PMCU-XXXX series of EMI/RFI common mode line filters from Premier Magnetics. The series includes various inductance values tailored for different noise suppression needs. The PMCU-0330 specifically addresses scenarios requiring moderate inductance for standard power line filtering applications.

Replacement Considerations

Check for direct substitutes within the PMCU series or equivalent components from other manufacturers offering 33 mH @ 1 kHz and 400 mA ratings. Ensure pinout and physical dimensions match if space constraints exist.
