WCM5555FASV-102-LM

Overview

The WCM5555FASV-102-LM is a surface mount common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features a two-line configuration designed for noise suppression in electronic circuits. The component exhibits an impedance of 1 kOhms at 100 MHz and supports a current rating of 3 Amperes. Its direct current resistance (DCR) is specified at 20 mOhm. The device is packaged in a horizontal SMD form factor with four PCB pads, suitable for automated assembly processes.

Feature Summary

• Surface mount construction for automated placement
• Two-line common mode filtering capability
• AEC-Q200 qualified reliability standard

Applications

• Embedded systems noise suppression
• Industrial automation signal integrity
• General electronics EMI filtering

Procurement Notes

Verify the exact part number suffix to confirm impedance and current ratings, as variations exist within the series. Confirm AEC-Q200 compliance requirements if automotive standards are mandatory. Ensure the horizontal package footprint matches the design board layout before procurement.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for common mode noise reduction. The 3A current rating suits moderate power applications. Verify that the 20 mOhm DCR meets voltage drop constraints. Ensure the horizontal SMD package fits the available PCB real estate.

Part Context

This model belongs to the WCM5555FASV-SERIES-LM line of wire wound power common mode filters. The series includes variants with different impedance values such as 700 Ohms and 500 Ohms, supporting currents up to 4.5A. All units share similar horizontal surface mount packaging characteristics.

Replacement Considerations

Cross-reference with other 1 kOhm @ 100 MHz, 3A common mode chokes in horizontal SMD packages. Verify pin compatibility and thermal performance before substitution.
