Overview
The PMCU-6011 is a through-hole common mode choke manufactured by Premier Magnetics, designed for power line filtering applications. It features two lines and supports a maximum current rating of 500mA with a rated voltage of 250VAC at 50/60 Hz. The component exhibits an inductance of 20mH measured at 1kHz and a maximum DC resistance (DCR) of 1.8 Ohms. Its physical dimensions include a maximum height of 18.00mm. This device serves as a replacement for specific Murata part numbers within the same product family.
Feature Summary
- Provides common mode noise suppression for dual-line power circuits
- Engineered for through-hole mounting on printed circuit boards
- Rated for 250VAC operation at standard 50/60 Hz frequencies
Applications
- Power line EMI filtering in electronic equipment
- Noise suppression in AC power input stages
- Replacement for discontinued Murata components in existing designs
Procurement Notes
Verify that the required inductance value of 20mH at 1kHz meets the specific noise attenuation requirements of your circuit design. Confirm that the 500mA current rating is sufficient for the maximum load current to prevent saturation. Ensure the 1.8 Ohm DCR does not cause excessive voltage drop or thermal issues in your application. Check mechanical clearance for the 18.00mm height constraint during PCB layout.
Selection Notes
Select this component when a 20mH inductance is required for common mode noise reduction in low-current power lines up to 500mA. It is suitable for designs needing a direct replacement for specific Murata parts. Consider the through-hole package type if surface mount options are not feasible. Evaluate the 1.8 Ohm resistance impact on power efficiency before finalizing the selection.
Part Context
This component belongs to the Premier Magnetics PMCU series of common mode chokes, which are designed to replace certain Murata products. The series offers various current ratings ranging from 0.3A to 2.0A. The PMCU-6011 specifically targets applications requiring moderate inductance values with through-hole compatibility, fitting into the broader portfolio of power line filters offered by the manufacturer.
Replacement Considerations
The PMCU-6011 is documented as a replacement for Murata part number PMCU-6003. Verify pinout compatibility and mechanical footprint alignment when substituting these components in existing assemblies.
