WCM 1211FASV-701-LM

Overview

The WCM 1211FASV-701-LM is a two-line common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. It is designed for surface mount applications and features a horizontal package with four pad contacts. The component provides an impedance of 700 Ohms at 100 MHz and supports a current rating of 9 Amperes. Its direct current resistance (DCR) is specified as 5 milliohms. This wire-wound power filter is constructed to handle high-current requirements while effectively suppressing electromagnetic interference in power line circuits.

Feature Summary

• Surface mount construction for automated assembly
• High current handling capability for power lines
• Wire-wound design for effective noise suppression

Applications

• Power line filtering in high-current applications
• Electromagnetic interference suppression in electronic devices
• Common mode noise reduction in power supplies

Procurement Notes

Verify the exact part number including suffixes against official manufacturer documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference datasheet specifications for thermal performance and mounting orientation to prevent installation errors. Ensure compatibility with your PCB footprint design before ordering.

Selection Notes

Select this component when high current capacity is required alongside common mode noise filtering. The low DCR minimizes power loss in high-current paths. Verify that the surface mount package fits your board layout constraints. Consider the impedance frequency characteristics to ensure effective filtering at your target noise frequencies.
