Overview
The WCM3216F2SF-222T02 is a two-line common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features a surface mount design with dimensions of 3.20 x 1.60 mm and a height of 2.00 mm. The component provides a common mode impedance of 2.2 kΩ at a test frequency of 100 MHz. It has a maximum DC resistance (DCR) of 1.2 Ω and a rated current of 200 mA. The device operates within a temperature range of -40°C to +125°C and belongs to the WCM series.
Feature Summary
- Provides effective common mode noise suppression for high-frequency signals
- Compact surface mount footprint suitable for space-constrained designs
- Low DC resistance minimizes signal loss in power or data lines
Applications
- High-speed data line filtering
- USB interface noise suppression
- HDMI signal integrity protection
Procurement Notes
Verify the exact part number suffix against official manufacturer documentation to ensure correct impedance and tolerance specifications. Confirm package dimensions and reel packaging details prior to ordering. Cross-reference datasheets for thermal performance limits under specific load conditions to avoid operational discrepancies.
Selection Notes
Select this component when low profile SMT packaging is required for two-line circuits. Ensure the operating current does not exceed 200 mA to maintain performance. Verify that the 2.2 kΩ impedance at 100 MHz aligns with the target noise frequency spectrum. Check compatibility with automated placement equipment due to the small 3216 case size.
Part Context
This component is part of the WCM series from TAI-TECH, designed for surface mount applications. It serves as a passive filter element in electronic assemblies requiring EMI reduction. The product remains active in the manufacturer's portfolio, indicating ongoing availability for new production designs.
Replacement Considerations
Consult official substitution lists for equivalent impedance and current ratings. Verify pin configuration and physical dimensions match the existing PCB layout before replacing.
