Overview
The PMCU-0220 is a common mode choke from Premier Magnetics designed for power line filtering. It features a two-line through-hole construction with an inductance of 22 mH at 1 kHz. The component supports a maximum current rating of 500 mA and has a maximum DC resistance of 1.2 Ohms. It operates within an AC voltage rating of 250 V and functions reliably across a temperature range of -40°C to 80°C.
Feature Summary
- Provides EMI/RFI suppression for power lines via common mode filtering
- Utilizes through-hole mounting for secure PCB integration
- Engineered for high inductance performance at standard test frequencies
Applications
- Power supply input filtering
- AC line noise reduction
- Electronic equipment EMI suppression
Procurement Notes
Verify the specific package dimensions and lead configuration against your PCB footprint requirements before ordering. Confirm that the 500 mA current rating meets your circuit's peak load demands. Ensure the operating temperature range aligns with your environmental conditions. Cross-reference the datasheet specifications to guarantee compatibility with your system's voltage ratings.
Selection Notes
Select this component when a 22 mH inductance value is required for common mode noise attenuation. Consider the 1.2 Ohm DCR limit if voltage drop across the choke is a critical design parameter. The through-hole format is suitable for applications requiring robust mechanical stability. Evaluate the 250 V AC rating to ensure safety compliance for your specific line voltage application.
Part Context
This part belongs to the PMCU series of EMI/RFI common mode line filters manufactured by Premier Magnetics. The series is designed for general-purpose power line filtering applications. The PMCU-0220 specifically denotes the 22 mH inductance variant within this product family, offering standardized performance characteristics for industrial and commercial electronics.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify pinout and electrical parameters carefully when considering alternative components from other manufacturers.
