WCM5555FASV-101-LM

Overview

The WCM5555FASV-101-LM is a surface-mount common mode choke from the WCM5555FASV-LM series, manufactured by TAI-TECH Advanced Electronics Co., Ltd. It is designed for power line EMI suppression in two-line configurations. Key electrical parameters include an impedance of 100 Ohms at 100 MHz, a maximum DC resistance (DCR) of 6 mOhm, and a rated current of 8.5 A. The component operates within a temperature range of -40°C to 125°C and carries AEC-Q200 automotive ratings.

Feature Summary

• Provides effective electromagnetic interference suppression for dual-line power circuits
• Complies with AEC-Q200 automotive qualification standards for reliability
• Utilizes surface mount technology for automated assembly integration

Applications

• Automotive electronic power supply filtering
• EMI suppression in vehicle infotainment systems
• Noise reduction in automotive sensor interfaces

Procurement Notes

Verify the complete part number including suffixes to ensure correct impedance and current ratings. Confirm AEC-Q200 compliance requirements match your specific automotive application standards. Check datasheet specifications for thermal management needs during operation. Ensure surface mount footprint compatibility with your PCB design constraints before ordering.

Selection Notes

Select this component when high current handling up to 8.5 A is required alongside low DC resistance. The 100 Ohm impedance at 100 MHz suits specific frequency noise profiles. Consider the -40°C to 125°C operating range for harsh automotive environments. Compare against other series members if different impedance or current values are needed.

Part Context

This component belongs to the WCM5555FASV-LM series of wire-wound power common mode filters. The series offers various impedance options while maintaining consistent physical dimensions and mounting characteristics. These chokes are engineered for robust performance in demanding electronic applications requiring reliable noise attenuation.

Replacement Considerations

Check equivalent parts from TAI-TECH within the same series for alternative impedance values. Verify that any substitute maintains the 8.5A current rating and 6mOhm DCR limits. Ensure the replacement supports the same surface mount package and AEC-Q200 certification.
