WCM2012F2SV-221T03

Overview

The WCM2012F2SV-221T03 is a surface-mount common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features a 2012 (0805) metric package with dimensions of 2.00mm length, 1.20mm width, and 1.20mm height. The component provides an impedance of 220 Ohms at 100 MHz with a tolerance of ±25%. It has a maximum DC resistance (DCR) of 400mOhm and a rated current of 300mA. The device supports a DC voltage rating of 50V and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Dual-line construction for common mode noise suppression in signal and power lines
• Surface mount design compatible with automated assembly processes
• Robust thermal performance supporting operation up to 125°C

Applications

• Common mode filtering in high-speed data interfaces
• RF choke applications requiring compact form factors
• Noise suppression in portable electronic devices

Procurement Notes

Verify the complete part number including suffixes such as 'T03' which indicates packaging specifications. Confirm that the required impedance tolerance and current ratings align with circuit design constraints. Ensure compatibility with surface mount reflow soldering profiles specified by the manufacturer. Cross-reference the AEC-Q200 qualification status if automotive reliability standards are mandatory for the target application.

Selection Notes

Select this component when space constraints require a 0805 footprint for common mode chokes. Consider the 300mA current rating and 400mOhm DCR for low-power signal lines. Evaluate the 220 Ohm impedance at 100 MHz against the specific frequency spectrum of interference to be suppressed. Ensure the 50V DC rating exceeds the maximum operating voltage of the protected circuit.

Part Context

This component belongs to the WCM_V series of wire wound common mode chokes from TAI-TECH. The series offers various impedance values and current ratings within standardized 0603 and 0805 packages. These components are designed for general-purpose EMI suppression in consumer electronics and industrial equipment where small size and reliable performance are prioritized.

Replacement Considerations

Check for direct substitutes within the same WCM2012F2SV series with different impedance values if electrical characteristics differ. Verify mechanical compatibility with existing PCB footprints before considering alternative manufacturers. Ensure any replacement meets the same AEC-Q200 qualification if used in automotive contexts.
