Common Mode Chokes Procurement Notes

Verify the exact part number RL-4400-1-0,90 against manufacturer datasheets to confirm specifications such as inductance tolerance and thermal ratings. Ensure compatibility with existing PCB footprint dimensions and lead spacing requirements before procurement. Confirm that the 1A current rating meets the operational demands of the target application to prevent saturation or overheating issues during use.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-frequency noise suppression in power circuits. The 900 mH value at 10 kHz indicates suitability for attenuating lower frequency interference. Consider the 1A current limit and 190 mOhm DCR to ensure minimal voltage drop and power loss in the specific circuit path where it will be installed.

Common Mode Chokes Part Context

This component belongs to the family of common mode chokes produced by Renco Electronics, Inc., specifically utilizing their Mini U-Core construction method. These components are designed to provide effective electromagnetic interference suppression in electronic systems requiring robust filtering capabilities within a standard through-hole form factor.

Common Mode Chokes Replacement Considerations
