Common Mode Chokes Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal ratings. Ensure the mounting hole pattern matches the PCB layout, as the vertical package requires specific clearance. Confirm that the 1.4 A current rating aligns with the maximum load requirements of the target circuit to prevent saturation or overheating during operation.

Common Mode Chokes Selection Notes

Select this component when both common and differential mode attenuation is required on AC lines. The 1.4 A rating suits moderate power applications. Verify that the 300 V rated voltage exceeds the peak line voltage. Consider the physical size constraints due to the 17.5 mm height and 18 mm length of the vertical housing.

Common Mode Chokes Part Context

This part belongs to the Murata PLY10 series of hybrid choke coils. These components are engineered for AC line filtering applications where space efficiency and high performance are necessary. The series typically offers robust construction for industrial and consumer electronics environments requiring reliable noise suppression on power inputs.

Common Mode Chokes FAQ

What is the difference between the common mode and differential mode inductance values?

The common mode inductance is 1.4 mH, which suppresses noise appearing in phase on both lines. The differential mode inductance is 110 uH, which attenuates noise appearing out of phase between the lines.

Is this component radiation hardened?

No, the specifications indicate that the PLY10AN1421R4D2B is not radiation hardened.
