Common Mode Chokes Feature Summary

• Utilizes amorphous core technology for high-performance common mode noise suppression.
• Designed for radial leaded PCB mounting to facilitate automated assembly processes.
• Capable of handling high DC currents up to 19 A while maintaining low insertion loss.

Common Mode Chokes Applications

• Data line filtering in industrial communication systems
• Noise suppression in power supply input stages
• EMI reduction in consumer electronics signal lines

Common Mode Chokes Procurement Notes

Verify the specific inductance tolerance requirements against the -30% to +50% specification provided by Pulse Electronics. Confirm that the 19 A current rating aligns with the operational load of the target circuit. Ensure the through-hole package dimensions fit the designated PCB footprint without mechanical interference. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Common Mode Chokes Selection Notes

Select this component when high current capacity is required alongside effective common mode noise attenuation. The 1.62 mH inductance value is suitable for filtering lower frequency interference compared to standard signal chokes. Consider the physical size constraints as the radial leaded package occupies significant board area. Evaluate the thermal performance at +125°C maximum operating temperature to ensure reliability under sustained load conditions.

Common Mode Chokes Part Context

This part belongs to the PH9455 series of common mode chokes manufactured by Pulse Electronics. The series utilizes amorphous core materials to achieve superior magnetic properties compared to traditional ferrite cores. These components are engineered for robust performance in demanding environments where high saturation current and stable inductance are critical for system integrity.

Common Mode Chokes Replacement Considerations

Cross-reference with other PH9455 series variants such as PH9455.150NL or PH9455.151NL if different inductance values are acceptable. Verify that substitute parts maintain the same 19 A current rating and radial leaded package style to ensure mechanical compatibility.
